        How to match subwoofers and amplifiers

        Find the right amp for your sub or sub for your amp

        How to match subs and amps

        The secret to great bass is making sure your subwoofers and amp are evenly matched and will properly work together. And this article will help you figure out how to do just that — match amplifiers and subwoofers.

        Getting the right sub for an amp, or the right amp for a sub, is like solving a puzzle. A subwoofer has impedance (measured in ohms) which represents the "load" an amplifier will sense on its output. An amplifier will put out different amounts of power (watts RMS) based on the impedance load it "sees."

        Solving the puzzle

        The amplifier's capabilities (X watts RMS into Y ohms) needs to match the subwoofer's specifications (Y ohms and can handle X watts RMS). Your goal is to get those two variables to match for both the amplifier and the subwoofer.

        Below, we cover the important basics of power-matching, impedance, and planning for the number of subs you want, and we approach the situation from both sides of the system:

        • Part A: You have the subs, which amp should you get?
        • Part B: You have the amp, which subs should you get?
        • And also, Part C: You have neither amp nor sub, and want help deciding how to begin.

        Start with either part you want, but A and B are both worth a read.


        Part A — You have the subs, which amplifier should you get?

        The subwoofers need to be the same

        Multiple subs wired together must be the same coil type and impedance. If they’re not, the power won’t divide evenly between them, and some subs would probably be over-powered while others get under-powered. If you want to run different types of subs in a system, each type needs to have its own separate amp.

        Step 1: How much power? Find out the “watts RMS” rating of the sub

        Then, multiply the number of subs you have by the RMS rating of each, to get their total RMS rating. You want to make sure the amp you choose will supply no more than the sub system’s total RMS rating.

        Step 2: What impedance? The results of combining coils and subs

        Figure out the possible total impedance(s) that the subs can be wired together to form.
        (SVC = single voice coil, 1 pair of terminals; DVC = dual voice coil, 2 pairs of terminals.)

        • 1 SVC 2-ohms can only have 2 ohms of impedance
        • 1 SVC 4-ohms can only have 4 ohms of impedance
        • 1 DVC 2-ohms can have 1 ohm or 4 ohms of impedance
        • 1 DVC 4-ohms can have 2 ohms or 8 ohms of impedance
        • 2 SVC 2-ohms can have 1 ohm or 4 ohms of impedance
        • 2 SVC 4-ohms can have 2 ohms or 8 ohms of impedance
        • 2 DVC 2-ohms can have 2 ohms or 8 ohms of impedance
        • 2 DVC 4-ohms can have 1 ohm or 4 ohms of impedance
        • 3 SVC 2-ohms can have 6 ohms of impedance
        • 3 SVC 4-ohms can have 1.3 ohms of impedance
        • 3 DVC 2-ohms can have 1.3 ohms or 3 ohms of impedance
        • 3 DVC 4-ohms can have 2.7 ohms or 6 ohms of impedance
        • 4 SVC 2-ohms can have 2 ohms or 8 ohms of impedance
        • 4 SVC 4-ohms can have 1 ohm or 4 ohms of impedance
        • 4 DVC 2-ohms can have 1 ohm or 4 ohms of impedance
        • 4 DVC 4-ohms can have 2 ohms or 8 ohms of impedance

        For more combinations of subs and their impedances, see Subwoofer Wiring Diagrams.

        Step 3: Pick an amp that can do both — X watts at Y ohms

        Look for an amplifier that can put out power up to the RMS wattage  you’ve figured in Step 1, at an impedance load the subs can be wired to form, from Step 2.

        Estimating amp power at the odd impedance values:

        • 8 ohms — figure on the amp putting out half the power it would at 4 ohms
        • 6 ohms — figure on the amp putting out three-quarters of the power it would at 4 ohms
        • 3 ohms — figure on the amp putting out the average of what it would at 2 ohms and at 4 ohms
        • 2.7 ohms — figure the same as for 3 ohms, and add a few watts
        • 1.3 ohms — use the 1-ohm spec and take away a few watts
        Alpine Type R SWR-843D

        Example:
        You have two Alpine Type R SWR-8D4 8" subwoofers and you want the right amp for them.

        They are DVC 4-ohm subs rated at 350 watts RMS each.

        Two 350 watts RMS subs together need a total of 700 watts RMS.

        Using the chart in Step 2, 2 DVC 4-ohm subs can be wired together to form a 1-ohm, a 4-ohm, or a 16-ohm load.

        The last is too high a load to be practical, so you’ll look for an amp that can put out up to 700 watts RMS into either a 4-ohm load, or a 1-ohm impedance load:

        • up to 700 watts RMS x 1 at 4 ohms, or
        • up to 700 watts RMS x 1 at 1 ohm

        Among Crutchfield’s selection of amplifiers you’ll find:

        Any one of these high-quality amplifiers would work well with those subs. It doesn’t matter which impedance an amp plays through — 600 watts RMS through a 4-ohm load produces the same volume as 600 watts RMS through a 1-ohm load.

        JL Audio Slash 600/1v3 subwoofer amplifier

        Part B — You have the amplfier, which subs should you get?

        Step 1: What can the amp do? Find the RMS ratings of the amp at different loads

        Find the amp’s power, expressed in “watts RMS”, at 4 ohms, at 2 ohms, and, if it can, at 1 ohm. Pick the power you’d like to achieve. The load impedance (ohms) of that rating will be what you want your subs’ total impedance to be.

        Step 2: How many subs do you want?

        Divide the power you picked in Step 1 by the number of subs you want. This number is the target RMS rating for each of the subs you’ll choose. 

        Step 3: What impedance does each sub need to be and how many voice coils?

        Using the impedance you picked in Step 1 and the number of subs from Step 2, cross-reference the possible coil configurations that you can use: 

        1-ohm 2-ohms 4-ohms
        1 sub DVC 2-ohms SVC 2-ohms
        DVC 4 ohms
        SVC 4-ohms
        DVC 2-ohms
        2 subs SVC 2-ohms
        DVC 4-ohms
        SVC 4-ohms
        DVC 2-ohms
        SVC 2-ohms
        DVC 4-ohms
        3 subs (1.3 ohms)*
        SVC 4-ohms
        DVC 2-ohms
        (3 or 2.7 ohms)*
        DVC 2-ohms
        DVC 4-ohms
        (6 ohms)*
        SVC 2-ohms
        DVC 4-ohms
        4 subs SVC 4-ohms
        DVC 2-ohms
        SVC 2-ohms
        DVC 4 ohms
        SVC 4-ohms
        DVC 2-ohms
        * Estimate amp power at the odd impedance values like in Part A, Step 3, above.

        Step 4: Pick a sub that works for both — (SVC or DVC) X-ohms, Y watts RMS)

        Look for subs that are rated at the wattage you figured in Step 2, and are configured as you found in Step 3. This might sound confusing, so let's walk through an example and it'll make sense.

        Memphis Audio 16-SRX500D.1

        Example:
        You have a Memphis Audio SRX500D.1 amplifier and you want it to drive two subwoofers

        The amp is capable of 350 watts RMS x 1 at 4 ohms and 500 watts RMS x 1 at 2 ohms.

        Let’s say you choose to maximize the amp’s potential and want the system to put out 500 watts RMS. This means your subs have to be wired to form a total impedance of 2 ohms.

        Two subs on a 500 watts RMS amp will want about 250 watts RMS each.
        So you’ll look for subs each rated for 250 watts RMS or more.

        Using the chart in Step 3, for two subwoofers, a final 2-ohm load can be achieved with either two SVC 4-ohm subs or two DVC 2-ohm subs.

        So, you’ll look for two subs that are either SVC 4-ohms or DVC 2-ohms, rated for at least 250 watts RMS each:

        • 2 SVC 4-ohms, at least 250 watts RMS, or
        • 2 DVC 2-ohms, at least 250 watts RMS

        Among Crutchfield’s selection of subwoofers you’ll find:

        Kicker CompC 10"

        Kicker CompC 10" component subwoofer

        All these subwoofers will sound their best when amplified with the proper amount of power. Differences in size have more to do with tonal qualities and frequency response than with power performance. And optimizing performance is the point of matching subs and amps together.


        Part C — You have neither amp nor sub, and want help deciding how to begin

          Hello. I have a 2016 Camaro SS with the factory head unit. I just purchased a Alpine X-A90V 5-Channel amp along with two 12" SVC Rockford Fosgate Prime R/1 (R1S4-12) subwoofers. Each sub is capable of running at either a 100w RMS x4 + 500w x1 @ 2 OHM load or 75w RMS x4 + 300w x1 @ 4 OHM load. Mounting both subs in a Dual Dual 12" Rear Fire Subwoofer Box manufactured by Subthumps specifically designed for my car. What is the best wiring configuration, at a 2 or 4 OHM load as well as the recommended size gauged wires would work best so that I can maximize the subs performance?

          Aures, Whether they're the DVC 2-ohm or 4-ohm versions of that sub, without knowing precisely which ones you're referring to, we can't help you with advice. If you want a question answered about a system, you must identify the gear by brand names and model numbers so we can get the right information to you.

This worked fine but now the Subwoofer has gone bust and the same model is no longer available. Could you pls suggest a suitable subwoofer brand for home use compatible with this Amp or what specs i should look for in the SubWoof. Specs for the Amp -- [link removed]

          Hello, I currently have a JL Audio JD1000/1 Amplifier. The specs are as follows: Rated Continuous (RMS) Power @ 14.4 V @ 4 O 600 W RMS x 1 @ 3 O 800 W RMS x 1 @ 2 O 1000 W RMS x 1 @ 1.5 O N/A Rated Continuous (RMS) Power @ 12.5 V @ 4 O 500 W RMS x 1 @ 3 O 650 W RMS x 1 @ 2 O 800 W RMS x 1 @ 1.5 O N/A How do I know if I am using 14.4V or 12.5V? Also, I am trying to pair it with a Kicker CompQ 12" which comes in a 2ohm and 4ohm option and they are both rated for 850 watts RMS. Both have dual voice coils. What would be the best router to go in order to get the most power out of my amp and sub without overpowering or underpowering it too much? Thank you for your help.

          Fernando, I'm not familiar with that sub, but if your specs are correct, your two DVC 4-ohm subs rated for 1500 watts RMS each will work great with an amp that can put out up to 3000 watts RMS at 1- or 4-ohms, like a Rockford Fosgate T2500-1bdCP.

          Jesse, That amp will probably blow that sub. A DVC 4-ohm sub rated for 600 watts RMS will work best with an amp that can put out up to 600 watts RMS at 2 ohms, like an Alpine S-A60M.

          Buck Pomerantz from Crutchfield

          on 12/7/2020

          Randy, The reason your amp shuts off is because it can't drive that low of an impedance load from bridged channels.

          on 11/11/2020

          Paul, I don't how that gear can be hooked up together. That sub wants an amplifier that can put out up to 1200 watts RMS at 2 ohms. The amp you mention can't come close to that, mismatching both impedance and power.

          on 11/5/2020

          MJ, You should never use max or peak specs when deigning a system. Use that "nominal" rating, also known as RMS rating, in your planning. Two SVC 4-ohm subs rated for 300 watts RMS each will work well with an amplifier that can put out up to 600 watts RMS at 2 ohms, like an Alpine S-A60M.

          Buck Pomerantz from Crutchfield

          on 11/3/2020

          Lupe, You can power a SVC 4-ohm sub, or a DVC 2-ohm sub wired at 4 ohms, with up to 150 watts RMS from a pair of bridged channels of that amp.

          I have 2 Punch P2 15inch old school subs in a ported box. Can't find the details on them to figure out if my amp is enough. They are not hitting very hard even after tuning. I have a Planet Audio Anarchy 1500 watt amp. Any help sure appreciated.

          Buck Pomerantz from Crutchfield

          on 11/2/2020

          Gerie, Those subs come in two models: DVC 2-ohm and DVC 4-ohm. Let's presume your subs are wired correctly to the amp, two DVC 2-ohm subs wired to 2 ohms, two DVC 4-ohm subs wired to 4 ohms. Each sub carries a 400 watts RMS power rating, 800 watts RMS together. Now that Class AB amplifier carries a 30A fuse, so it won't be able to put out more than about 210 watts RMS, a lot less than the subs can handle. Give us a call so an Advisor can set you up with an amp that can get those subs hitting hard.

          Arturo, You should not set your subwoofers on a back seat - that's very dangerous, boxes will fly and hurt someone in the event of an accident. Give us a call, so an Advisor can help you pick out the subs and amp that'll fit properly in your vehicle and sound great.

          I'm looking at getting two Kicker CompRT DVC 2ohm subs with 600watt max each and 300watts RMS. The amp I'm looking at is the Kicker CX400.1. It says 400 watt class. Am I reading the article correctly on how to pair speakers and amps?

          Buck Pomerantz from Crutchfield

          on 10/26/2020

          Chris, You can wire those subs to that amp like this, and the amp will send the two 300 watts RMS rated subs, 600 watts together, 400 watts RMS, which may sound fine to you. But there is room for improvement.

          on 10/23/2020

          Ernest, A single DVC 4-ohm sub rated for 400 watts RMS will work best with an amplifier that can put out up to 400 watts RMS at 2 ohms, like a Sound Ordnance M350.

          I have a Picasso Soundstream Nano P640d with a dedicated sub-channel pushing 350W @ 2ohms. I know a lot of folks like to overpower subs, but my question is: if I'm looking for a healthy mix of pressure & quality, should I look for a sub that is rated for close to 350W, or should I go for something rated lower and overpower it slightly? Is a lower-rated (RMS wise) sub going to be louder with 350W than a sub rated for 350? I'm also wary to buy a sub that is rated for more power than my amp puts out, as I know I'll want more power and end up driving it too hard/dirtying up the signal and probably clip it. Any advice? Thank you!

          Buck Pomerantz from Crutchfield

          Sean, If you want a warranty honored on a new sub, do not give it more power than its top RMS wattage rating.

          Buck Pomerantz from Crutchfield

          on 9/23/2020

          Kevin, It sounds like you have two 2-ohm subs wired together in parallel and presenting a 1-ohm load to the amp, which can't handle it. If you have the switchable impedance subs, switch them both to 4-ohms.

          Hello, I have an Audison SR5 amp, 2 front two way speakers (Audison Prima APK 165P, 115W RMS). I am planning to get a 4ohm Sub from Pioneer TS-WX306B (350W RMS). Will it be OK to drive it at 4 Ohms and 185W RMS of power? The 115W speakers are given 55W RMS at 4Ohms Are they considered underpowered? take a look at my amps specs please [link removed], P.S. my desire is to have the best audio quality available, that is why I am only going to run the speakers and sub at 4 Ohms only. In the future I am planning to install a rear identical set of speakers. So that is why I have a 5 channel amp.

          on 9/21/2020

          Tassos, The final impedance of a speaker or sub has absolutely no bearing over the quality of the sound. Also, there's no such thing as under-powering a speaker - it'll just play quieter.

          Buck Pomerantz from Crutchfield

          on 9/16/2020

          Andres, If your subs are the DVC 2-ohm models, it's a good match. If they're the DVC 4-ohm subs, then not so good. That amp takes 4-gauge power and ground wire. Subs can take 16-, 14-, or 12-gauge wiring.

          on 9/13/2020

          Blake, That's a great amplifier, and may produce a satisfying amount of bass for you, but those two 750 watts RMS rated subs would sound better powered with an amp about three times more powerful than the one you have.

I can only wire my subs down to a 2 ohm total impedance. So I'm going to be safely sending 1200watts under a 2 ohm load. Nothing has been installed yet. I'm wondering if I am going to have a good quality sound, or if I'm falling short of full potential. I'm not looking to be as loud as I can get just clean powerful sound. This is my first upgrade and have questions before I do the install. Thank you for your help.

My goal is to get laud as much as i can with what i have.So , not interested in very low bass. The thing is, those subs looks the same and they are same watts. My multymeter shows 0.5 ohms. That would actually be 1ohm,right? Dual 2ohms connected into 1ohm and than connected the second sub which is 1x4ohm. They are both joined in a single wire which than goes into amp. Am i safe with that ? Or should i leave them as 2ohms? Please help

          Buck Pomerantz from Crutchfield

          on 8/7/2020

          Dragunov, It is possible to wire these two subs together with that amp. First, wire the DVC 2-ohm sub as a 4-ohm load, like this. Then, wire the two subs together to the amplifier like this.

          on 5/18/2020

          Kenner, Those 4-ohm 600 watts RMS rated subs, wired together as a 2-ohm load, will work great with an amplifier that can put out up to 1200 watts RMS at 2 ohms, like a Kicker KXA1200.1.

          I have Rochford t2d2 the okder one with aluminum bullet proof dust cover powered by the jl hd600/1 the impedence is 1.5 ohms I assuming some how it's a dual 3ohm woofer. But the? Is can the jl hang because it's the best bass you will ever hear I made the box to specs. I'm a 30 yr car audio installer. That's not my age either. This little jl I picked up for 25$ at a junkyard. Picked up W6 same day for 25$ also. But the T2 makes the W6 want to hide in shame.

          on 4/27/2020

          Gary, If the sub you're referring to is a Rockford Fosgate T2D2 sub, it's DVC 2-ohm and can only be wired as a one-ohm or a 4-ohm load. That amp can put out 600 watts RMS at 1.5 to 4 ohms. You should wire yours like the diagram in the link.

          on 4/24/2020

          Grant, A DVC 4-ohm sub rated for 300 watts RMS will work best with an amplifier that can put out up to 300 watts RMS at 2 ohms, like a Rockford Fosgate P300X1.

          Buck Pomerantz from Crutchfield

          on 4/21/2020

          Vincent, Those subs are each rated for 450 watts RMS and wired together in parallel will present a 1-ohm load to the amp. So look for an amplifier that can put out up to 900 watts RMS at 1 ohm, like a Kicker KXA800.1.

          Buck Pomerantz from Crutchfield

          on 5/4/2020

          Levi, A 1000 watt amp will probably destroy a 300 watts rated sub.

          Buck Pomerantz from Crutchfield

          on 4/16/2020

          Kenner, Power comes from the amplifier. Generally speaking, an amplifier will put out more power through a 2-ohm sub than it would through a 4-ohm sub.

          Buck Pomerantz from Crutchfield

          on 4/14/2020

          Andrey, That sub is rated for 400 watts RMS. It'll work best with an amp that can put out no more than 400 watts RMS at 2 ohms, like a Sound Ordnance M350-1.
        • Andrew from Massapequa

          Posted on 4/11/2020

          So to make sure I'm not confused with my first DVC sub experience. I have two 4ohm DVC subs, 500w max RMS. The amp I have is 350x1 @4ohm, and 1000x1 @1ohm. Wiring it as 1ohm is ok, adding each sub is 500w each? With the ratings you add the subs RMS together, even though they're wired to 1 channel? Thanks (again)

          Buck Pomerantz from Crutchfield

          on 4/13/2020

          Andrew, You should never use max power ratings when planning out a system. Use RMS ratings only. If you have two identical subs wired correctly to a 1000 watts RMS amplifier, each sub will receive 500 watts RMS.

I have the amp's gain turned down significantly but when I turn the sound up on certain basslines one of the speakers will make a popping noise. I'm trying to figure out if it's too much power causing it or not enough airspace in the box. The box is a front facing subs under the seat in a truck with the port facing the back passenger side door. The sub closest to the port is the one making the popping noise so I figured it might be the airspace but not sure

If they are compatible what is your suggestion for wiring the subwoofer. Do you have a better match suggestion (I need it for a compact enclosure, nothing to fancy just something that punches and works)

          Buck Pomerantz from Crutchfield

          on 4/7/2020

          Oscar, That amp is too powerful for that sub. That dual voice coil (DVC) 4-ohm sub can only be wired as an 8-ohm or a 2-ohm load. To be safe, you'll want an amplifier that can put out no more than 200 watts RMS at 2 ohms. Or you could pick out a stronger sub for that amp.

          Marshall, That amp and sub will work together, but not very well. The DVC 2-ohm sub can only be wired as a 1-ohm or a 4-ohm load. The amp can't handle the 1-ohm load, and would only be able to send 350 watts RMS to the 1000 watts RMS rated sub.

          G, Alpine makes six versions of their S Series subwoofers. The amplifier that'll work best for yours will depend of which model sub you have - whether it's DVC 2- or 4-ohm..

          I have two ddx 12 dual 4ohm 1000 rms/1500peak on a skar to.1500. Nice boom and I love the set up. But I know the subs can take more. My problem is which amp I need to be looking into for more bass without haveing too much of a pull on my electric

          Demarcus, Two DVC 4-ohm subs rated for 1000 watts RMS each will work well with an amp that can put out up to 2000 watts RMS at 1 ohm, like a Kicker CXA1800.1T.

          Buck, I hope you can help me soon. I currently have this sub: MTX Square TS8512-44 12" Dual Subwoofer 4 Ohm (Peak-1500 watts, RMS-750 watts). I had this sub connected to it: MTX JackHammer JH600 Class D Mono amp (350 watts RMS x 1 at 4 ohms (600 watts RMS x 1 at 2 ohms)) but it died last year. It was replaced with: hX-400.2 2-channel Full Range Class D Amplifier (I am not at home so I don't actually know the brand; this is all the info I have), but it is not as powerful as my jackhammer. What is the best amp to look for to power my sub?

          on 11/30/2019

          Faye, Your DVC 4-ohm sub rated for 750 watts RMS will sound best with an amp that can put out up to 750 watts RMS at 2 ohms, like a Memphis Audio SRX750D.1.

          Buck Pomerantz from Crutchfield

          on 11/30/2019

          Benjamin, That amp can send two subs a total of 1200 watts RMS, 600 to each sub. The subs you mention are rated for twice that, so may sound under-powered with that amp.

          Hi, I have a 12W1v3-2 by JL AUDIO fitted into the FJ Cruiser Stealthbox housing. According to JL Audio it pushes 300 watts wired 2 ohm mono. I currently have a RD500/1 by FL Audio accompanying the sub. My sub blew out recently, and it's been replaced as of 5 days ago. I had the sub-woofer serviced prior to it blowing out since it was cutting "in and out" of sound. My local audio place assured me it was the gain coming out of the amplifier so they turned it up on their own terms. I believe the sub blew because they started to clip once the audio place turned the gain up. I got the new sub-woofer placed in the box and I'm getting the same cutting when I experience road turbulence or making a turn. Power seems to phase in and out of strength as well without completely shutting down as a turn/turbulence would. Am I receiving too little power? Is a fuse blown? Ground connection? Wire connection? Voltage? Not too sure, hate to present such a complex issue but I wish that your solution helps.

          Buck Pomerantz from Crutchfield

          on 11/5/2019

          Dillon, The main issue I see here is that the amp is powering a 300 watts RMS rated sub with 500 watts RMS. Over-powering, really - there should be no surprise that it blew.

          Buck Pomerantz from Crutchfield

          on 10/29/2019

My initial plan was to use the gain to keep from overpowering the sub but the more I read I think that is the wrong way to do it and should have went with a p3d4-10 wired at 2 ohm. What would you recommend?

          Buck Pomerantz from Crutchfield

          on 10/14/2019

          Joe, You're correct about that gear - the amp is too powerful for that sub. Either get a smaller amp, or a higher-rated sub.

          on 10/4/2019

          Joel, That sub comes in 2-ohm and 4-ohm versions. Maybe you've got a 4-ohm sub and it's receiving 225 watts RMS from that amp, which isn't enough for you or the 500 watts rated sub. If you want it louder you can get the 2-ohm version of that sub, or get a bigger sub amp that can put out 500 watts RMS at 4 ohms.

          Would a JX500/1D monoblock amp and an Alpine SWT-10S2 10" Subwoofer wired at 2 OHMS be a good combination? The sub is rated at 350 RMS, so would 500 W from the amp be too much?

          Buck Pomerantz from Crutchfield

          on 9/20/2019

          Matt, We recommend using an amplifier with output power equal to or less than the subwoofer's top RMS power rating, so that amp is a bit too powerful to safely power that sub.

          on 8/13/2019

          Brett, I can't tell you if that gear will work together without knowing precisely what subs you have. Dual makes two or more models with different coil configurations and impedances. I can tell you that that amplifier can put out 80 watts RMS x 2 at 4 ohms, 120 watts RMS x 2 at 2 ohms, and 240 watts RMS x 1 bridged at 4 ohms.

          I recently purchased two ts-swx2002 8in subs. If I've read the specs correctly they should both be DVC 2ohm a piece (though one site rated impedance at 4ohm) as well as 150w RMS a piece. Going off the examples given above, I would want to look in the 240 - 360 watt range correct? Also if I'm pairing them with a set of Kappa62ix speakers, which based on reviews on Crutchfield I'll get the best out of them when paired with an amp. Do I need to accommodate the size of my amp or would the above range of amp still be appropriate?

          Buck Pomerantz from Crutchfield

          on 8/7/2019

          Sarriola, Two DVC 2-ohm subs rated for 150 watts RMS each will work best with an amp that can put out between 225 and 450 watts RMS at 2 ohms. You subs have been pre-wired internally to effectively each be 4-ohm subs. Wired together in parallel, positive to positive and negative to negative, together they'll present the amp a 2-ohm load. A good rule of thumb for speaker/sub power is that a sub amp's power will match well with a full-range amp that has 10% of its power per channel. So, for example, a 500-watt sub amp will work well with a 50 watts per channel speaker amp.

          Six, Two DVC 8-ohm subs rated for 400 watts RMS each will work well with an amp that can put out between 600 and 1200 watts RMS at 2 ohms. The only practical way to wire those subs together is like this diagram, replacing the 4s in the diagram with 8s and the 1 with a 2. Either one of the amps you mention will work fine.

          Patrick, The only safe way to wire that gear together is like this, substituting your 1-channel amp for the 2-channel amp in the diagram. Otherwise that amp has enough power to blow that sub to pieces.

          Hey Buck, I have 3 of the Rockford Fosgate P2D2-8 wired up for 3 ohm and i know that i need an amp that can equal the 3 subs need rms but do i need an amp that can equal the max power to. The peak for the subs are 500 watts each. Do I need an amp that can push 1500 watts or just 500? know what i mean?

          Buck Pomerantz from Crutchfield

          on 7/25/2019

          Dakin, Never use peak specs. Always use RMS specs only. Your three DVC 2-ohm subs are rated for 250 watts RMS each, or 750 watts RMS for all three. They'd work best with an amplifier that can put out between 550 and 1100 watts RMS at 3 ohms, like JL Audio's JX1000/1, which should put out 750 watts RMS at 3 ohms.

          Buck Pomerantz from Crutchfield

          on 6/18/2019

          Juan, An internet search for that amp came up empty, but if it really can do 375 watts RMS, a couple of subs rated between 125 and250 watts RMS each will work well. Two JBL Stage 810 subs will work.

          I have 2 JL Audio 12TW3-D8 wired for a 2 Ohm Final Impedance @ 800W RMS in a JL Audio Stealthbox. I have a Rockford Fosgate Prime 1200.1D that does 800W RMS @ 2 Ohm ( though it's closer to 880W on a dyno). Is this enough wattage for this setup or should I look for something larger? The bass sounds amazing in my 2010 GMC Sierra 1500 Crew Cab but outside the vehicle the bass doesn't seem that loud at all. So just wondering if I need to step up the size of the amp or am I just being picky?

          Buck Pomerantz from Crutchfield

          on 6/17/2019

          Shane, That sub and amp have the same ratings - 2-ohms, 800 watts RMS. If you want more, I'd say don't go over 1200 watts RMS at 2 ohms, like with a Kicker CXA1200.1.

          I am thinking about buying Kicker's CompRT 12" Dual-Voice-Coil 2-Ohm Loaded Subwoofer Enclosure. I am not sure about what amp I should run along with it. I read this guide however this sub is rated as DVC and 2ohm. The specific sub in this is the kicker RT.

          Buck Pomerantz from Crutchfield

          on 6/7/2019

          James, If you're talking about Kicker's TCWRT122, it's a 2-ohm sub rated for 500 watts RMS. A good amp for it would be an amp that can put out between 375 and 750 watts RMS at 2 ohms, like a Kicker DXA500.1.

          I have two 15 inch SHOK industries subs that are 4ohms a piece. I never heard of this brand but with a little research lol I think they're pretty powerful@ 500 watts rms, not sure if that's true but I have an ARC AUDIO FD2200 AMP pushing them, and they hit! But my amp gets hot sort of quick which prevents me from turning the gain up high. I have the speakers wired in parallel to one channel. Curious...is this the right set up with what I have. I don't understand why the speakers cut out after a like 15 mins of playing

          Buck Pomerantz from Crutchfield

          on 6/5/2019

          Travis, Sounds like you have some wiring issues. If you have the Shok Triton subs, they're dual voice coil (DVC) 4-ohm subs, and they should get wired to that 2-channel amp like this.

          on 6/3/2019

          Miah, To optimize that amp's output to 500 watts RMS will take a DVC 4-ohjm sub, wired to 2 ohms, rated for between 330 and 660 watts RMS. like an Alpine S-W10D4.

          I just purchased a truck 2 days ago with a Pyle power pla4478 4 Ch 4000 Watts Bridgeable Mosfet Amplifier. It has two Kicker CompD 8 Inch 4 Ohm Subwoofers in a box under the seat, it was utilizing. I noticed a weird smell when I purchased the truck, but got side tracked with the excitement and additional features I was shown. Just today ((within 48 hours, and not messing with any of the radio settings)) the sub suddenly went silent. Later in the day I picked up a co worker who has done some light car audio and as soon as he got in my truck he said he could smell a speaker blown somewhere. We investigated and found only one to have the smell and some resistance when we gently pushed on it. When I got home I busted out my finances old ken wood sub just to see if it would power on. Nada. My friend says the owner of the truck, had way to much power for those little guys. I was wondering if this were accurate, and I'd also like to ask you Buck, what speakers would work/you'd recommend with this 4 Ch 4000 Watt Pyle. Thanks for doing this for all of us!

          on 5/20/2019

          Devon, That amplifier is probably capable of putting out four channels of 220 watts RMS or two channels of 600 watts RMS, which is more than twice the rating of those subwoofers. A better fit would be Hertz's ML 2000.3 subwoofers.

          Jordan, If you are referring to Sony's XS-L124P5B SVC 4-ohm subs, then two of them will sound great with an amp that can put out between 570 and 1140 watts RMS at 2 ohms, like a Kenwood KAC-9106D.

          on 4/13/2019

          Rocky, The best way to wire that gear together is like this. In this configuration, the amp can put out 800 watts RMS, 400 to each sub. If that's not loud enough, you could then get a bigger amp.

          Buck Pomerantz from Crutchfield

          on 2/12/2019

          James, The most that amplifier can put out is 500 watts RMS bridged through a 4-ohm load. And those two SVC 4-ohm 400 watts RMS rated subs can only get wired together as a 2-ohm or an 8-ohm load. You could power each of those subs with a single amp channel, like this, but then the power wouldn't match very well.

          Hey Buck, Thanks for the Great article. I'm curious though, in "Part A - Example", you are multiplying the RMS value by 0.75 & 1.5 to get the minimum and maximum RMS values. 700 watts RMS 75%: 525 150%: 1050 But in "Part B - Example" you are dividing the RMS value by 0.75 & 1.5 to get the minimum and maximum RMS values. 250 watts RMS 75%: 167 150%: 333 The correct way to find the percent of a number would be to "multiply" the RMS value by the Percentage. Is there some specific reason why you chose to "divide" in Part B rather than "multiply"?

          Buck Pomerantz from Crutchfield

          on 1/29/2019

          Ray, Because you are performing an inverse operation, matching subs to amp versus amp to subs, you need to use inverse functions, dividing instead of multiplying.

          Buck Pomerantz from Crutchfield

          on 1/24/2019

          Emma, 4-channel amplifiers are rarely suitable for subwoofers, but using this diagram as a guide, you could use two bridged channels of that amp to power a single sub like a JBL Stage 1010. Ohms are the measurement units of a device's resistance to the electrical pressure (volts) exerted through its input, resulting in output power measured in watts.

          on 10/22/2018

          Josh, You should not connect subs of different impedances together to the same amplifier - the lower impedance sub will get more power than the higher impedance sub, resulting in unbalanced sound levels and potentially blown subs. It may be best for that gear, to just run the one 2-ohm sub with that amplifier.

          I have been doing as much research as I can about subs and amps. I have 2 Audiopipe TXXBD412 , 4 ohm DVC. I am going to be wiring them parallel to 1 ohm. The total watt per sub is 2200 W and 1100W RMS. According to what I learned from your article, I will need an amp that can produce a total of 1650 rms (75% for both subs) to 3300rms (150% for both subs). I was debating on getting the Audiopipe APMI-2000 but after doing the math I don't fell it'll be powerful enough to push them. any advice or recommendations?

          Buck Pomerantz from Crutchfield

          on 10/10/2018

          Garry, Type R subs sound different than Type S subs, so changing subs will change the sound. Type Rs are less sensitive and rated higher than the Type Ss, so they'll play a bit quieter as well. They would absolutely benefit from getting more power - maybe four times the power of your present amp (which I assume is an Alpine MRX-M55).

          Tyler, A Kicker Comp 12" SVC 4-ohm sub is rated for 150 watts RMS. It will work well with an amplifier that can put out between 110 and 220 watts RMS at 4 ohms, like a JL Audio JX250/1D.

          I have 3 type r's black. In a ported box. I was running a soundstream mono block 3500 watt amp (a older one with the 2 120amp fuses in it. And some how the negative port melted down on it. What went wrong. I have a 2nd battery in the back and had the amp and batt grounded to the same spot in the back of my truck. Also what amp should I be using to push the 3 subs

          Will, Terminals and connectors get hot when the resistance to the current flow increases because of a loose connection or corrosion on the conductors. You have to constantly make sure that all connections are tight and clean, to maintain a working system.

          Good evening. I have a question. I was thinking about purchasing 4 Pioneer Ds-d12d2 subwoofers to run on 2 Rockford fosgate t10001bd. Or should 1 amp be enough. The rms on the subwoofers are 600 a piece and each amp is 1000. Im running a pioneer equalizer the 6500 series 9 band, audio control epicenter, and audio control crossover along with pioneer head unit.

          George, You could wire two of those subs to each amp like this, and each 600 watts RMS rated sub would get 375 watts RMS. A better deal for those amps would be if you got the DVC 4-ohm model subs (TS-D12D4). Wired like this, each sub would get 500 watts RMS.

          Matt, the sub you mention presents a 4-ohm load to the amp, so that won't maximize the amp's power. A better match would be a 2-ohm sub rated for between 300 and 500 watts RMS, like a Rockford Fosgate Prime R1-2X12.

          Posted on 5/23/2018

          Harry, Those subs are DVC 4-ohms and rated for 2500 watts RMS each. For a single amp to power them would take about 10,000 watts. A better way might be to use four 2500-watt amps, like Rockford Fosgate T2500bdCPs.

          Alexander, A single DVC 4-ohm sub can only be wired as an 8-ohm or a 2-ohm load, so the best way to wire one to one of those amplifiers is like this diagram. The 400 watts RMS rated sub will handle 500 watts RMS just fine. Just make sure you set the amp gain so that no distortion plays.

          I guess I am making this comment/question to pre-visualize what I will be encountering when I get my new subwoofers installed on the 21st of this month. I have purchased two JL Audio 10Tw3-4's each with an RMS rating of between up to 400w and are both 4 ohm dual V coils. The "optimal" green zone on JL's website is showing the 250watt area. .. and anything over 500watt is in the black zone symbolizing being not recommended. ..... I own two Alpine MRV 500/1 amps.. one for each JL sub...... To simplify though let's pretend at this point I have just one sub and one amp....... The amp will be providing 500w RMS at 2 ohm.. *OR* 300w RMS at 4 ohm. - The JL website "danger scale" is seemingly going against the overall agreement that having more power *available* is better for subs than under powered.... ... so would I be better giving the sub its native 4 ohm parameter and output at a 300w RMS level (which would be 100w under the subs top spec of a 400w RMS rating.) or am I going to be taking a risk dropping to 2 ohm and throwing the full 500w RMS at it? (which would be 100w OVER the subs top spec of a 400w RMS rating.) side note of interest: Nowadays I go for an all-around full concert sound versus my "Basshead" days of simply trying to anger people hundreds of feet away with constant low end, so what matters to me now is giving my system the BEST arrangements for the best and safest dynamics. Thanks for providing any advice you have. =) Alexander

          Bryan, Two DVC 4-ohm subs get wired to an amp that can handle a 1-ohm load like this diagram. That 1200 watts RMS amp may be a bit much for those 420 watts rated subs, but they should be alright as long as you don't play distorted bass.

          Philip, Although some amplifiers can be "strapped" together in pairs to double the power, you should never connect amplifier outputs together, it could cause damage to both amps. Not knowing exactly what amplifier or subwoofer you have make it impossible to give advice on how to wire them together. If you want a question answered about a system, you must identify the gear by brand names and model numbers.

          Mark, 600 watts RMS is 240% of the RMS rating of your subs, so that amp will be a bit too much for them. You could probably use it, as long as you set the gain low enough to never play distortion.

          I have an older pair of JL Audio 12w0 version 1 8-ohm and according to the owners manual they are rated at 125 watts rms but it also show a range of 60 to 250 watts with 125 watts being the optimum level. Would a 600 watt rms amp be too much power for a pair of these subs? Can the 75 to 150 percent method be used from the 250 max rms rating?

          Posted on 11/30/2017

          Tony, A subwoofer acts like a passive inductive load with its impedance value measured in ohms. An amplifier will react differently to different loads - an amp that can put out 125 watts RMS through a 4-ohm load will often be able to put out twice that, 250 watts RMS, through a 2-ohm load. It's like lifting weights: your arms (the amplifier) don't change when you change weights (the load/ohms), but your effort and work output (the power/watts) do.

        • Tony from Bowling Green

          Posted on 11/30/2017

          Thanks, Buck. Another quick question. When the amp says it can do either 125watts rms x 2 @ 4ohms or can do 250watts rms x 2 @ 2 ohms. How do you select for it to be the 2 ohms for both of the channels instead of the 4 ohms on each channel? Or is there no selection and it just automatically puts out a 2ohm load and a 4 ohm load per channel?

        • Buck Pomerantz from Crutchfield

          Posted on 11/30/2017

          Tony, That gear will work well together. Wired like this diagram, the amp will put out 250 watts RMS to the 300 watts RMS rated sub. Then later, you can add a second sub wired like this, and have a 500 watts RMS subwoofer system.

          Corey, Two DVC 4-ohm subs will work best with an amplifier that can put out between 900 and 1800 watts RMS through either a 1-ohm or a 4-ohm load, like a Pioneer GM-D9601. The amplifiers you mention can't do that.

          Arjun, A SVC (single voice coil) 8-ohm subwoofer rated for 300 watts RMS will work best with an amplifier that can put out between 225 and 450 watts RMS at 8-ohms. Look for an amp with an output spec of between 450 and 900 watts RMS at 4-ohms.

          Hi, I am curious to which Amplifier to buy for my TWO new Pioneer TS-W3003D4 12" 2 DVC 4 Ohm @ 2 O or 8 O Impedance. Each Subwoofer is 2000 Watts Max/600 Watts RMS EACH(All together I have 1200 Watts RMS power). I don't know much about Amplifiers but, I get an idea on what kind of amp to run off of the article. I need your approval. From the setup of subs I run, I have two amps I have in mind. Which one you prefer that will work the best? The Rockville dB13 3000 Watt/1500 Watt RMS Mono D 2 Ohm, OR, the Boss Phantom. PT 2600 Watt class A|B 4 Channel 2 or 4O 1300 Watt RMS? Also, if neither are suitable, can you tell me what kind of other amp is better? Means and helps a lot if I get feed back. Please and thanks. ,Corey F.

          Marca, The lengthy description you've given contains no useful information on which to base any advice on what amp would work for your sub. If you want a question answered about a system, you must identify the equipment by brand names and model numbers, not advertising copy.

          Sikholiwe, Not knowing exactly what amplifier or subwoofers you have make it impossible to give advice on how they were matched or mismatched in your system. If you want a question answered about a system, you must identify the equipment by brand names and model numbers.

          I had a sound system installed in my car with the following sound system parts: - AMP rated at 6900 Watts RMS, I don't know the impendence. - Two Subs each rated at 2000 Watts RMS, I don't know the impendence. Four days after installation the subs blew up. Using your guidelines for matching Subs and AMP, my calculation results reveal that an AMP rated between 3000 to 6000 Watts RMS would have been suitable for the 2000 Watts RMS Subs which I have. Similarly, Subs rated between 2300 to 4600 Watts RMS would have been suitable for the 6900 Watts RMS AMP that I have. I would like to know if the mismatch between the AMP and the Subs could have been the reasons for the Subs to blow up. Thanks

          Ajith, That amplifier will require a power supply with a 12 to 14 volt DC, 60-ampere output. Then, it would require 4-gauge (6 mm) power and ground wires. A subwoofer rated between 400 and 800 watts RMS, either SVC 2-ohms or DVC 4-ohms will work best. Then, you'll need an enclosure for the sub to work properly. Seems like a lot of trouble and expense, instead of getting a home theater subwoofer designed to work in the home.

          Thomason, I don't know anything about that amplifier, or even what audio gear is available in your country. It appears that two of your subs are DVC 2-ohm models and the other four are DVC 4-ohms. You should never connect subs of different impedances together to the same amplifier - the lower impedance subs will get more power than the higher impedance subs, resulting in unbalanced sound levels and potentially blown subs. Get two amplifiers for your two different types of subs.

          Will, Two SVC 8-ohm subs get wired to a bridged 2-channel amp like this. That amplifier can then send out a total of 1100 watts RMS, 550 watts RMS to each 1000-watt rated sub. It'll work, but the subs would work better with an amplifier about twice as powerful.

          Kyle, If your two DVC 4-ohm subs are wired correctly to a 1-ohm stable amplifier, like this, when the amp puts out 2400 watts RMS, each sub will receive 1200 watts RMS.

          Adrian, An 08DS12L72 is a single loaded enclosure with two 12-inch component subs with a total impedance of 2 ohms and a power rating of 1500 watts RMS. Changing from a 1500-watt amplifier to a 1000-watt amp will not improve the sound. I suggest re-tuning the gain, bass boost, low-pass filter, and subsonic filter on your existing amp will improve things better than adding new gear. Check out this article for help tuning your sub.

          James, The safest way to connect that gear together is to set the amp in High-Current mode (1-ohm capable) and wire it like this. That way the amp will put out 450 watts RMS, just what that sub needs to shine.

          Kon, That 300 watts RMS rated 4-ohm sub will work best with an amplifier that can put out between 225 and 450 watts RMS at 4 ohms. Unfortunately, the amplifier you mentioned, in spite of its specifications, will not be able to produce even that much power. A Class AB amp with a 30-amp fuse will not produce more than about 210 watts RMS. A better choice would be a JBL GTX500.

          I have a Pioneer (TSSWX2502) 10-Inch shallow-mount subwoofer and a pair of Kicker CS654 speakers in the front. Amazon recommends BOSS AUDIO R1100M Riot 1100-Watt Monoblock amplifier for the sub I have. Trying to decide on an amp. I'm new to car audio scene (not well knowledged on impedance either). What do you suggest?

          Posted on 4/27/2017

          Michael, Your mono, 1-channel amplifier has 2 speaker output terminals that are wired together inside the amp. The second speaker output terminal is there for convenience and if you hook a sub to each terminal it would result in the two subs being wired in parallel, cutting the total impedance in half. If you wire a 2-ohm sub to each terminal, that amp would go into protect mode to prevent burning up. I suggest getting a second amp to drive your second sub.

          I Have a MTX thunder 1000xd amp its a mono block and has 2 sets of +,- terminals. Specs say RMS Power Rating: 4 ohms: 500 watts x 1 chan. 2 ohms: 1000 watts x 1 chan. I currently have a DVC 1ohm Kicker 12''comprt that is wired at 2ohms plugged into the amp using The + on one set of terminals and the negative on the other. (+-)(+-). Slightly over powered i know. Id like to add another sub using the same amp. My question is if I get another identical sub and connect them independently one on each terminal at 2ohms is that what the separate terminals are for on this monoblock amp? Can I even ad another sub while retaining my current sub? looking for peak performance don't want to have power that's not being utilized. Thanks!

          Mike, If you have DVC 4-ohm subs, either wiring scheme results in the same thing - the amp sees the same load per channel and the subs receive the same amount of power.

          Nikki, A power supply designed for a camera or lighting system will not work with those amplifiers, it's way too small. If you are determined to use that car audio gear in a home system, you'll need a power supply capable of putting out DC12V 92A 1105W. [If you're interested, here's the math: For the 4-channel amp to put out its full 60 watts RMS per channel, 240 total at 50% Class AB efficiency will require a 480 watts RMS supply. For the mono amp to achieve its 500 watts RMS output using 80% efficient Class D technology will require 625 watts RMS. 480 + 625 = 1105. 1105 watts divided by 12 volts equals 92 amperes.]

          Nikki, Not knowing exactly what amplifier or subwoofer you have make it impossible to give advice on how to power them. If you want a question answered about a system, you must identify the gear by model numbers as well as brand names. I can tell you that a 12-volt 20-amp power supply can support a 120 watts RMS Class AB amplifier or a 190 watts RMS Class D amplifier. If you want to add massive bass to your home system and a home theater subwoofer isn't loud enough for you, I suggest looking at a professional PA subwoofer. You can probably check one out at your local music store.

          Alex, A subwoofer's power rating is the manufacturer's recommendation of how strong an amplifier to use to safely drive it, and has nothing to do with the sub's output, which is heat and noise. That amp will work with that sub
