How to match subwoofers and amplifiers

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

In the 1950's, I'd take the family television's vacuum tubes down to Willow Grove Radio and TV Repair, check them with the giant tester machine, buy new replacement tubes, and reassemble the repaired television, so my mom and dad could enjoy their precious, respectively, Dean Martin and Red Skelton shows. In the 1960's, I studied radio and electronics at the Franklin Institute in Philadelphia. After college, in the early 70's, I joined a rock 'n roll band as the soundman, learning how to operate the electronics that make music sound good. Then, I worked in a music store in Austin manufacturing, installing, repairing, and operating sound systems and components for recording studios, nightclubs, and touring bands. I moved back to Charlottesville permanently in 1984 and opened a little demo recording studio. I also attempted to put to practical use the creative writing degree I had picked up along the way. In 2006, I finally came to my senses and got this job at Crutchfield where they actually pay me to ramble on, rant, and explain the things I love about music, electronics, and getting good sound.

How to match subs and amps

In a Nutshell

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."

Getting the right sub for an amp, or the right amp for a sub, is like solving a puzzle where 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.

Full Story

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. 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?

Start with either part you want, but they're both worth a read.


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

The subs 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 is capable of supplying from 75% to 150% of 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 within the RMS wattage range 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, but an amp putting out from 525 to 1050 watts RMS will do. (75% of 700 is 525; 150% of 700 is 1050.)

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 from 525 to 1050 watts RMS into either a 4-ohm load, or a 1-ohm impedance load:

  • 525-1050 watts RMS x 1 at 4 ohms, or
  • 525-1050 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.  Notice that the Rockford Fosgate Power T1000-1bdCP can play that pair of subs at 700 watts RMS or 1,000 watts RMS, if you want it louder, just by wiring them together differently.

Rockford Fosgate T1000-1bdCP

Rockford Fosgate T1000-1bdCP subwoofer amplifier

The last amp listed above, the Rockford Fosgate Power P1000X2, is a 2-channel amp that happen to work with these two subs when bridged into 1-channel mode. But multi-channel amps are typically lower-powered than mono subwoofer amps, and usually can’t drive loads lower than 4 ohms when bridged.


Kicker 43CXA1200.1

Kicker CXA1200.1 subwoofer amplifier

Part B
You have the amp, 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.

  • Divide that target number by 1.5. This is the lowest RMS rating per sub that will work.
  • Divide that target number by 0.75 for the highest RMS rating per sub.

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 within the wattage range 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.
250 divided by 1.5 is 167; 250 divided by 0.75 is 333. So you’ll look for subs each rated between 167 and 333 watts RMS.

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 between 167 and 333 watts RMS each:

  • 2 SVC 4-ohms, 167-333 watts RMS, or
  • 2 DVC 2-ohms, 167-333 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.

    i have recently bought a subwoofer 200 watt at 4 ohm , 19 cm . I have made by myself subwoofer box capable of adding at least 3 more subwoofers in it . My question is that is it possible to add other subwoofers at 2 ohm in case if i dont find 4 ohm . And if the total watt is around 800 watt , which amplifier is good ?

  • Buck Pomerantz from Crutchfield

    Posted on 4/27/2015

    Samy, 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. If you do get four SVC 4-ohm subwoofers with the same 200-watt power rating, you can wire them together like this diagram. Look for a mono subwoofer amplifier that can put out from 600 to 1200 watts RMS at 4 ohms.

  • Buck Pomerantz from Crutchfield

    Posted on 5/4/2015

    Robin, Not knowing exactly what subwoofers you have (number of voice coils and impedance) make it impossible to give advice on how to wire them together. Also, I am not familiar with any Alpine subwoofer rated for 750 watts RMS, and suspect you've quoted a peak rating, which is useless for matching subs and amps together. There are no benefits in getting a 2-channel amp to drive a subwoofer system. Most 2-channel amps can't drive loads lower than 4 ohms when bridged, and don't have enough power to drive 2 subs. Mono, 1-channel amps are designed to work with a wider range of impedances, and have tone controls and filters specifically made to help reproduce bass.

    9000watts pmpo equal to how many ohms

  • Buck Pomerantz from Crutchfield

    Posted on 5/11/2015

    Gopinath, A watt is a measurement of an amplifier's output power; an ohm is a measure of a subwoofer's impedance; a number of one can't equal a number of the other - they're different things. They do have a mathematical relationship when the sub is hooked up to the amp. An amplifier's output power in watts will equal its output voltage squared then divided by the subwoofer's impedance in ohms. Also, you should never use peak ratings when matching amps and subs (PMPO stands for Peak Momentary Power Output, a worthless rating), always use RMS ratings.

    I am looking at buying ONE sub which will best suite my amp. The amp I got is a Phoenix Gold Ti21600.5 (five channel amp) which can supply 500rms at 4 ohm or 800rms at 2 ohm to the sub line. The sub I am looking at buying is rated at 600rms and I have the option of taking it as a 2 ohm dual voice coil or a 4 ohm dual voice coil. Should I opt for the 2 ohm DVC or the 4 ohm DVC version of the sub?

  • Buck Pomerantz from Crutchfield

    Posted on 5/12/2015

    Dylan, If you want 500 watts of bass, get the DVC 2-ohm model and wire it like this diagram. If you want 800 watts of bass, get the DVC 4-ohm model and wire it like this. That sub should have no problems with that much power.

  • Buck Pomerantz from Crutchfield

    Posted on 5/12/2015

    Rajeev, Car subwoofers are inappropriate in a home stereo system for a number of reasons. If you wanted to power your sub with just 500 watts RMS, the 12-volt power wires would need to be able to pass about 55.6 amperes of current. That large a power supply is rare and expensive. If a home theater subwoofer is not large enough for your planned system, try looking at a pro audio PA subwoofer. I don't know what pro audio equipment is available in your country, but an online search ought to bring up at least one pro audio dealership somewhere near you.

    I have 3 DVC 2 ohm 300 watt RMS each. I am looking to wire them to 3 ohm. Now here is my question...I am looking a amplifier to push these subs at its peak power. ( E8V3D2 Sundown Audio) Should i be looking for a 2 ohm stable amp with 600-1200 Watt RMS ? 1200 RMS being its peak?

  • Buck Pomerantz from Crutchfield

    Posted on 5/15/2015

    David, Three DVC 2-ohm subwoofers can indeed present an amplifier with a 3-ohm load, wired like this diagram. The math for figuring what an amp will do with that impedance is a bit complicated and I won't go into it here. I will tell you that you should look for a mono subwoofer amp (2-ohm stable) capable of putting out from 1000 to 1500 watts RMS at 2 ohms. This should result in between 750 and 1125 watts RMS for the 3-ohm system - right on target. Avoid amps with regulated output power that is the same at all impedances - that won't work the same way.

    Posted on 5/17/2015

    I have a Rockford Fosgate Punch 400.4, 4 channel amp that's about 14 years old, and it was only used for less than a year. I was wanting to use it again, and was wanting to buy 2 subs. I know 4 channel amps are not ideal for subs, but it worked great for my last system years back. I guess bridging it to a 2 channel is what the installers did with it. On the amp, it says "50 X 4 Watts RMS into 4 Ohms with less than 0.05% THD from 20-20 KHz." It also states "100 X 4 Watts RMS into 2 Ohms with less than 0.10% THD from 20-20 KHz." What kind of subs would work with this amp? Or should I just not use this amp and buy a newer monoblock or 2 channel and wire that to 2 new subs? Thank you for any help!

    Hi i have picked up some kicker CVR12 subs and they are wired at 1ohm so i have been told i have an RF P8002 amp can i use this amp they way they are wired if not how do i wire them? Yes old amp but never used.

  • Buck Pomerantz from Crutchfield

    Posted on 5/18/2015

    Matt, If your amplifier is the old Punch 400.4, then here's a link to the Owner's Manual. To run two subs, you hook it up in 2-channel mono mode as shown on page 23. That way you can drive two subs with up to 200 watts each. Make sure the subs you get are each rated for between 150 and 300 watts RMS, and are either SVC 4-ohm or DVC 2-ohm models, so you can wire them to each bridged channel at 4 ohms.

  • Buck Pomerantz from Crutchfield

    Posted on 5/18/2015

    Damian, Kicker CVR subwoofers come in DVC 2-ohm and DVC 4-ohm models. If by "some" subs you mean two, and they really are wired together to form a one-ohm load, then they're the DVC 4-ohm subs. For that amplifier, you need to re-wire them like this diagram.

    I am looking at buying two 12" subwoofers that are 1150 RMS, 4 ohm impedance, and DVC. I would like an amp to match. I am using your walkthrough to try and figure out which amp to buy but I am just getting confused with the last step. So if you could tell me which type of amp I should get for my subs, it would be greatly appreciated.

  • Buck Pomerantz from Crutchfield

    Posted on 6/1/2015

    Ben, Do you mean you want to run two DVC 4-ohm subs each rated for 1150 watts RMS, 2300 together? Then you'd look for a mono subwoofer amplifier that can put out between 1800 and 3500 watts RMS at 1 ohm or at 4 ohms.

  • Tom from Chicago

    Posted on 6/4/2015

    In the example, with the Kenwood Excelon X500-1 amplifier "Two subs on a 500 watts RMS amp will want about 250 watts RMS each. 250 divided by 1.5 is 167; 250 divided by 0.75 is 333. So you'll look for subs each rated between 167 and 333 watts RMS." Why are you dividing by 150% and 75%. It should be a multiplication, resulting in 250*.75=187.5 250*1.5=375

  • Buck Pomerantz from Crutchfield

    Posted on 6/5/2015

    Tom, When you try to find an amplifier to match known subwoofers, you multiply the sub's rating by 150% and 75% to get the power range of the amp needed. When you do the inverse, try to find matching subs to a known amplifier, you must also invert the mathematical operation. Using your math, you'll find that two 375-watt rated subs would hardly work with a 500-watt amplifier, which would only supply 67% of the subs' power rating.

    I have a kicker amp with a 600 watt max and a 300 watt rms @ 2 ohms. I have one cerwin vega 8'' sub 250 watt rms dual voice coil with 2 ohms. Would my amp be powerful enough to power 2 of those subs?

  • Richard from CA

    Posted on 6/7/2015

    I don't see why you would bother to bridge a two channel amp to drive a dual voice coil speaker. You would simply be driving the impedance of the individual voice coils by each channel of the amp. Somebody needs to review dual voice coil technology.

  • Buck Pomerantz from Crutchfield

    Posted on 6/8/2015

    Greg, The short answer is no, your amp doesn't put out enough power for two of those subwoofers. In fact, it barely has enough power for one.

  • Buck Pomerantz from Crutchfield

    Posted on 6/8/2015

    Richard, You are correct, Sir. DVC technology is difficult and confusing to understand. It was put in place to expand the wiring options for subwoofer systems, but made the actual wiring and impedance-matching more of a challenge.

  • Greg from phoenix, az

  • Buck Pomerantz from Crutchfield

    Posted on 6/17/2015

    Greg, If that amplifier is the Cadence DAKOTA then it can put out 400 watts RMS to your 250-watt RMS rated sub, which should be just fine. Wire them together this way.

    Posted on 6/22/2015

    Ben, You don't bridge subwoofers, you bridge amplifier channels together. But yes, you can connect your gear together like this diagram. Don't expect 500 watts of power for each sub however. Those specs are "Max Power" ratings, which are exaggerated, misleading, and only used by manufactures for advertising.

  • Buck Pomerantz from Crutchfield

    Posted on 6/23/2015

    Jake, Alpine Type S subs come in two models: DVC 4-ohm and DVC 2-ohm. If yours are the DVC 4-ohm subs, then you should look for an amp that can put out between 750 and 1500 watts RMS at 1 ohm or 4 ohms. If you have the DVC 2-ohm subs, then you should look for an amp that can put out between 750 and 1500 watts RMS at 2 ohms. The size power and ground cables you'll need depend on which specific amplifier you choose and will be specified in the amplifier's owner's manual and specs.

    Posted on 6/24/2015

    Doyle, Both those amps will send the same amount of power, 400 watts RMS, to those two subs wired together like this. "Peak," "Max," and "Dynamic" ratings are exaggerated, misleading, and only used by manufactures for advertising their gear as being louder than the next guy's. Only use RMS specs.

  • Buck Pomerantz from Crutchfield

    Posted on 6/24/2015

    Anthony, For your subs, look for a mono subwoofer amplifier that can put out between 600 and 1200 watts RMS into a 2-ohm load. As for your full-range speakers, look for a 4-channel amp that can put out 75 to 100 watts RMS per channel at 4 ohms.

    Justin, That amplifier's specs say that it can put out 150 watts RMS when bridged to a 4-ohm load. Not knowing exactly which sub you have makes it impossible for me to give wiring advice. I can tell you that you need to set your amp's low-pass filter and gain correctly. Check out this article for help doing that.

Will my amp be good for these subs? It is also available in a 4 ohm option, should I look at that over a 2 ohm option? Or should I look at different subs altogether? Thanks

    Bobby, The subwoofer channel of the Alpine PDX-V9 will put out 500 watts whether to a 2-ohm or a 4-ohm load, so it really doesn't matter which of those subs you get. If you get the 2-ohm models, wire them together like this. If you get the 4-ohm models, wire them like this.

  • Buck Pomerantz from Crutchfield

    Posted on 7/8/2015

    Jarrod, Look for a 2-channel amplifier that can put out between 75 and 150 watts RMS at 4 ohms.

    I got done installing two 12in Rockford Fosgate Series One subwoofers to a Pioneer GM-A5602, but unfortunately the subs were old and couldent handle the newer technology and blew out... so im now looking to but two new subs. The power rating for my amp is [150x2@4ohms / 225x2@2ohms] What power rating subwoofer should i be looking at?

  • Buck Pomerantz from Crutchfield

    Posted on 7/9/2015

    Eric, You have a lot of options, but you'll get the best bang out of that amp if you get subs rated for between 150 and 300 watts RMS. They can be either DVC 4-ohm subs, or SVC 2-ohm subs.

I don't know if it's because I'm used to a sealed box enclosure but the subs do not sound too great. Should I buy a different amp? Or do you have any suggestions on a sub, enclosure, amp combo to install in a 2012 Toyota Sienna SE.

    I have (2) SVC 12" subwoofer 875W max power 175W continuous power if the amp I want has these specs will it be good enough for lots of bass at high volume Maximum power output: 1200 watts Max power @ 2 Ohms: 600 Watts x 2 RMS power @ 4 Ohms: 200 Watts x 2 Frequency response: 9 to 50,000 Hz 200W RMS output

  • Buck Pomerantz from Crutchfield

    Posted on 7/10/2015

    Erick, That amplifier will put out about 250 to 300 watts RMS to that subwoofer, which should be fine. Perhaps your system just needs a little tune-up. Check out this article for help with that.

  • Buck Pomerantz from Crutchfield

    Posted on 7/10/2015

    Mike, First of all, you need to ignore max ratings, they are meaningless. Secondly, you didn't say what impedance your subs are, so it'll be a challenge to figure out which amp will be best for them. If they're SVC 4-ohm subs, look for an amp that can put out between 300 and 500 watts RMS at 2 ohms. If they're SVC 2-ohm subs, 300 to 500 watts RMS at 4 ohms.

  • Buck Pomerantz from Crutchfield

    Posted on 7/14/2015

    Derek, If you're referring to the MTX TNP212D2 Dual Loaded Subwoofer Enclosure then you should first know that it's rated for 400 watts RMS. (You should never use peak specs.) In order to drive this sub, look for an amplifier that can put out between 300 and 600 watts RMS at 2 ohms.

  • Buck Pomerantz from Crutchfield

    Posted on 7/15/2015

    Stacey, I suspect that the specs you quote are peak ratings that have no real use in matching your amp and subs together safely. But not knowing exactly what amplifier or subwoofers you have make it impossible to give advice on how to wire them together. If you want a question answered about your system, you must identify your equipment by brand names and model numbers.

  • Buck Pomerantz from Crutchfield

    Posted on 7/17/2015

    Thegan, You might be able to bridge a couple channels of your 4-channel amplifier together to drive your subwoofer, if it's 4-ohms, but generally speaking, it's better to use a mono subwoofer amp to run a subwoofer.

  • Buck Pomerantz from Crutchfield

    Posted on 7/20/2015

    Eriz, The Boss Audio R1100M amp will put out close to 400 watts RMS into 4 ohms, which should be enough power to run two 300 watts RMS subs. Of course, they will sound better with a more powerful amp, all subs do.

  • Buck Pomerantz from Crutchfield

    Posted on 7/21/2015

    Ricardo, I'm not sure what you want to accomplish with two full-range 2- way coaxial speakers plus two tweeters in a system, but you can certainly run them with those amps. As to whether it'll sound awesome or not will be up to you. I'd expect it to sound a bit heavy on the high frequencies, but you may like it like that.

  • Buck Pomerantz from Crutchfield

    Posted on 7/21/2015

    Nelson, One of those subwoofers wired to that amplifier like this would perfectly match the 750-watt amp with the 750-watt sub. You could wire three of those subs wired together to that amp like this, but then the amp would only be able to put out about 500 watts and those would be divided between the three subs. In order to maximize the potential of those subs you'd need a much more powerful amp, like the Kicker 40KX2400.1 for instance.

I would like to get the alpine MRV-F300 4 channel amp (50 watts rms x4 @ 4ohms, 75 watts rmsx4 @2 ohms). it is bridgeable in the rear channel for a 2.1 channel (dual with sub) setup.

  • Buck Pomerantz from Crutchfield

    Posted on 7/23/2015

    Malaquiaz, I don't know what a Rockford Fosgate P2S2 is - Googling it comes up empty. However, that amplifier will power two P2D4-8s just fine, wired together like this.

  • Buck Pomerantz from Crutchfield

    Posted on 7/23/2015

    Jake, That amplifier should work fine with your speakers and sub. Figure 12 in the owner's manual shows how to hook it all up, with a speaker connected to channel 1 and one to channel 2 and a subwoofer connected to channels 3 and 4 bridged together. You'll need to wire the sub like this.

    I have 4 15 inch subwoofers American bass XO 1000 watts max peak. 500 watt RMS I have connected to two Jensen power 760 amplifiers bridged my amps keep overheating and going into protection mode why is that?

  • Buck Pomerantz from Crutchfield

    Posted on 7/27/2015

    Andrew, If your subs are Bass XO1544s, the reason your amplifiers are going into protect mode is that you probably have each sub wired as a 2-ohm load and your amps are only stable down to 4 ohms when bridged. The only way to wire your equipment together safely is like this. Unfortunately you won't get much bass out of it, seeing as each 500-watt sub will only be getting about 80 watts RMS.

My concern is is the subs going to be to much power for my amp and eventually blow my amp up ? Some buddies of mine said i will need a new alternator or an extra battery along with a new amp to power subs like those. I already have a Cap but im still new at this and just need some advice.

  • Buck Pomerantz from Crutchfield

    Posted on 7/28/2015

    Ryan, Trying to run two 1500-watt subs with a 400-watt amp won't blow the amp, but wiring them together incorrectly might. Seeing as SoundQubed HDC 12" subs come in DVC 1-ohm and DVC 2-ohm models it is crucial that you know which model you have in order to wire them safely to an amplifier. That 400-watt amplifier shouldn't stress the electrical system of whatever vehicle you have. But if you do put in a stronger amp and then your vehicle's lights dim when the music plays, then you might need to upgrade your electrical system.

    I have a Rockford Fosgate Punch 400 x 4 Amp (200w x 2 @ 4 Ohms Bridged) and a JL Audio 10TW3-D4 (200-400w Dual 4 Ohm). Can I use this amp to power this sub? If so, how should I wire it? I'd like to Bridge the amp and run two channels, one to each VC. Concerned about the dvc ohm rating. Or should I get a new amp?

  • Buck Pomerantz from Crutchfield

    Posted on 7/29/2015

    Jason, It's not the best of practices, but your scheme will work. Wire each voice coil to a pair of bridged amp channels. Use this diagram as a general guide, but pretend that instead of two subs, they're two voice coils on one subwoofer. That sub can easily handle the amount of power that amp puts out. The tricky part is that each channel must send the identical signal to its coil or the discrepancies will create distortion and may even damage the sub. You solve this issue by using a Y-cord to send the same signal to each amp channel.

  • Buck Pomerantz from Crutchfield

    Posted on 7/31/2015

    CJ, You didn't say how many subs you have, but I'm going to guess two. The best you can do with that gear is to wire it all together like this diagram. At a total potential output of 500 watts RMS, I see no need for a second battery in your system.

  • Buck Pomerantz from Crutchfield

    Posted on 8/5/2015

    Alex, It might not be such a good idea to run those subs with that amp - at the 2 ohms they can get wired at, each 400-watt rated sub could get up to 700 watts RMS, which is enough to blow it apart. You could get it to work successfully if you set the amp's gain down low enough so that it won't put out a dangerous level of power.

  • Buck Pomerantz from Crutchfield

    Posted on 8/5/2015

    John, It sure will - set the sub's impedance to 2 ohms and rock on.

  • Buck Pomerantz from Crutchfield

    Posted on 8/6/2015

    Donnell, Many people use a multimeter to set their amplifier gains, but it's not absolutely necessary. Setting gain using a AC volt meter to attain the RMS voltage for a targeted wattage depends on the meter's accuracy at the frequency played. And setting by number doesn't tell you if the signal's clipped or not. Check out this article, where I discuss a few ways to set amplifier gain properly.

  • Buck Pomerantz from Crutchfield

    Posted on 8/11/2015

    Joel, Part of the complexity of matching subs and amps is that not only do you need to match sub impedance with amp capability, but you have to consider both of their RMS power ratings as well. Not knowing exactly what amplifiers or subwoofer you have make it impossible to give advice on how to wire them together. If you want a question answered about your system, you must identify your equipment by brand names and model numbers.

    Hi Buck, Thanks for the great article. I have a just purchased a Hertz DS 30.3 Subwoofer which will be delivered to me this week. I got it for a steal, which is why I started my build with the subwoofer. It has a continuous program rating of 250 watts, and a peak of 500 W. Is the Blaupunkt EMA 455 a suitable amplifier (4 channel, 55 RMS)? It is available for under 70 USD here. I am looking at a 4 channel amp with a bridge so that I can power my front components (Blaupunkts, OE of the Skoda Octavia Mk1) through the amp as well. In the rear, I have a set of 4.25 inch coaxials (Stock location, Hertz, don't know the model) which I plan on running through the headunit directly. Which other amplifiers should I consider? Does the set-up seem okay? What kind of wiring do I have to do for this? These seem to be very naive or amateurish questions, but this is my first proper car audio system! Please help!

  • Buck Pomerantz from Crutchfield

    Posted on 8/13/2015

    Viraat, Many people use a 4-channel amp the way you describe: front channels running front speakers and the rear channels bridged to run a subwoofer. The owner's manual for your new amplifier will include wiring diagrams to help you hook it up.

  • Buck Pomerantz from Crutchfield

    Posted on 8/17/2015

    Mark, I don't know anything about that interface harness, but judging by its customer reviews it ought to work fine with your factory receiver, that equalizer and amp. I do see that you chose two 200 watts RMS rated DVC 4-ohm subs. Seeing as they can only get wired together to form a 16-, a 4-, or a 1-ohm load, you won't be getting the amp's full subwoofer output, because the amp can't do 1-ohm and will only be able to put out 200 watts RMS at 4 ohms. You'd do better with two DVC 2-ohm subs wired like this.

  • Buck Pomerantz from Crutchfield

    Posted on 8/17/2015

    Kendall, Pioneer TS-TRX60s are full-range speakers, not subs, and they have a 50 watts RMS rating, so any 2-channel amp that can put out around 50 watts RMS a channel will work fine for your pair.

  • Buck Pomerantz from Crutchfield

    Posted on 8/20/2015

    Robert, Pyle Audio makes two kinds of 600-watt 4 ohm subs: dual voice coil (DVC) and single voice coil (SVC). If yours are the DCV 4-ohm versions, then you'd look for a mono subwoofer amp that can put out between 800 and 1500 watts RMS at 1 ohm or 4 ohms. If you have the SVC versions, then the amp should be able to put out 800 to 1500 watts RMS at 2 ohms.

  • Buck Pomerantz from Crutchfield

    Posted on 8/20/2015

    Marc, I'm not familiar with that brand of sub and amp, nor what's available Down Under, but that Rockford Fosgate amp is a great amplifier and would provide those subs with enough power to sound great too.

    Hey Buck. I've got a 12" DVC 4ohm sub that I want to buy. Its advertised as 650x2 RMS with 5000W max output. Will a 4 channel 6000W with RMS of 80x4ohm be suitable?

  • Buck Pomerantz from Crutchfield

    Posted on 8/26/2015

    Brandyn, If you have a DVC 4-ohm sub rated for 1300 watts RMS, a 4-channel amp capable of putting out 80 watts a channel won't do it much good. For that sub, a mono, 1-channel subwoofer amplifier that can put out between 1000 and 2000 watts RMS at 2 ohms will work much better.

    James, Just because you have a 1000-watt amplifier doesn't mean you have to send all 1000 watts to your subwoofer. You can limit the level your subs see by setting the amp gains low enough to never allow them to be overdriven.

    Jaeden, That DVC 4-ohm sub can only get wired as a 2-ohm or an 8-ohm load, so using bridged amp channels won't do much good - low power on the 8-ohm load and the amp can't handle a 2-ohm load when bridged. Maybe the DVC 2-ohm model wired to 4 ohms will work, but I don't know exactly what amp you have so I can't suggest which sub would work better.

    I have a 10" Kicker 40CWRT101 1-ohm DVC and a JVC KS-AX3205D, both of which were put together by a crutchfield specialist. A friend and I DIY and hooked up only one side of the sub to the amp. We might have fried something because the sub won't work and it makes a pop sound and then nothing. What did we do wrong?

    Posted on 9/3/2015

    Rico, I can't imagine what you intended to accomplish by connecting a single voice coil of a dual voice coil sub to an amp. The amp, not stable for a 1-ohm load, tried to output over 300 watts RMS into a 1-ohm coil rated for 250 watts. Because you bought your gear from Crutchfield, you could call Tech Support for more free help troubleshooting your system. Their toll-free number is on your invoice.

    If I buy 1000w Rockford fosgate, will I be fine if I connect them to an 1100 watt boss amp?

  • Buck Pomerantz from Crutchfield

    Posted on 9/3/2015

    Daniel, Not knowing exactly what subwoofers you have make it impossible to give advice on how to wire them together. If you want a question answered about your system, you must identify your equipment by brand names and model numbers.

    Sorry sir, I have two Rockford fosgate 12's 500 watts each, and I'm wondering if an 1100 watt boss amp will be ok with them. If not, what should go to as far as watts in an amp for these speakers.

  • Buck Pomerantz from Crutchfield

    Posted on 9/5/2015

    Daniel, You still haven't identified your gear well enough for me to give you advice on hooking it up. But, if the amplifier you're referring to is a Boss R1100M, I would suspect its 200-watt RMS output won't pose much of a threat to two Rockford Fosgate subwoofers, no matter what their voice coil configuration, impedance, or RMS power rating may be. However, you can burn up the amp by hooking up the subwoofers incorrectly.

    I have one Pioneer TS-W1207D4 (12in. 4 ohm sub) and looking for an appropriate amplifier. The Pioneer website states this sub is rated at 400rms. Not sure if that is at 4ohm or 2ohm. I'm looking at an MTX Audio Thunder 500.1 monoblock to power it. It has 4 terminals however (+,+,-,-). Minimum 2 ohm load and 500rms Confused and need help figuring out the following: 1)Is the Pioneer sub rated 400rms at 2ohm or 4ohm? 2)Is the MTX AUDIO Amp good to power this type of sub? 3)How should I wire it considering the 4 terminals? (++--) I think this amp is bridged internally

  • Buck Pomerantz from Crutchfield

    Posted on 9/8/2015

    Peter, You can run three subwoofers with one amplifier, but the subs would all need to have the same impedance and power rating. The amp would have to have enough power to accommodate the sum of the RMS power ratings of all three subs.

  • Buck Pomerantz from Crutchfield

    Posted on 9/8/2015

    Travis, That sub is a dual voice coil (DVC) 4-ohm sub that can get wired as a 2-ohm or as an 8-ohm load and is rated for 400 watts RMS no matter which way it's wired. That amp will work fine wired this way. That mono, 1-channel amp has two sets of speaker output terminals, wired together inside the amp, for convenience when hooking two speakers in parallel.

  • Buck Pomerantz from Crutchfield

    Posted on 9/8/2015

    Sam, Amplifiers are divided into different classes defined by how their internal circuitry works. Discussion of Amplifier Class is irrelevant in an article about matching amps and subs together - all amps get wired the same way no matter what Class they are.

  • Buck Pomerantz from Crutchfield

    Malcolm, 500 watts RMS may be a tad too much for those subs but you should be okay as long as you keep the amp's sub channel gain set low.

    Hi Buck, I have the setup in the first example with 2 Alpine SWR-8D4 but am using an Alping PDX-M6 amp to power them. I have them wired together for a 4 ohm load also. My question after reading a lot on OHM's law and setting the amp gain for lower RMS power subs is what is your recommendation on my amp's gain setting. If I go with everything I've read and watched on getting the right amount of voltage from the amp my gain setting is at 0. Of course having the 2 subs wired together at a 4 OHM load is like you said in your example, a 700 watt 4 ohm load so do I need to worry about the amount of volts I'm pushing to subs by increasing the gain on my amp? Thanks Josh

  • Buck Pomerantz from Crutchfield

    Posted on 9/10/2015

    Cody, Yes, wired like this that amp should send those subs 700 watts RMS.

  • Buck Pomerantz from Crutchfield

    Posted on 9/10/2015

    Clayton, It may seem like using a 1000-watt amp to run a 300-watt sub might endanger the sub, but if the sub's coils are wired in series like this, presenting an 8-ohm load to the amp, you should be alright. Especially if you keep the gain set low and don't play distortion.

  • Buck Pomerantz from Crutchfield

    Posted on 9/10/2015

    Michael, Kicker makes two kinds of 10" CVR subs: dual voice coil (DVC) 2-ohm and DVC 4-ohm models. Which ones you have will affect what amp will work best. If you have the DVC 4-ohm models, you'll want an amp that can put out between 600 and 1200 watts RMS at 4 ohms or 1 ohm. If you have the DVC 2-ohm models, get an amp that can do 600 to 1200 watts RMS into a 2 ohm load. Kicker makes a few amps smaller than the 1200.1 that'll probably work, like their KX800.1 or CX600.1.

  • Buck Pomerantz from Crutchfield

    Posted on 9/10/2015

    Josh, I'm not sure what your concern is about your gear - the amp can put out 600 watts RMS to those subs, which together have a 700-watt RMS rating. As for setting the amp's gain, check out this article for some better methods of doing that.

    I have two 4x6" SPS-406 speakers, two 6.5" SPS-610 speakers & two 12" SWA-12S4 subwoofers. If i buy a PDX-V9 5 channel amplifier, will this work & if so how would i properly do this? I'm pretty sure the amp will handle the power for all these speakers but i'm not sure if i can use the (one) sub channel for both subwoofers... I also have 4awg wire & an 80 amp fuse.. Will that be sufficient size wire & amp for this setup? One last question is would it be better to use a capacitator or just get a yellow optima battery to handle all this power? Thank you in advance...

  • Buck Pomerantz from Crutchfield

    Posted on 9/24/2015

    Joel, Wire your two subwoofers to the sub channel of that amp like this, and they'll be able to receive 500 Watts RMS, perfect for two 250-watt rated subs. 4-gauge power and ground wiring are recommended for the amp. And I doubt you will need a capacitor or an extra battery for this setup.

    I currently have a kicker mono dx 250.1 wired with 8 guage wiring and a kicker comp 10 svc in a truck box in the back of my car. The specs for the amp are 150rms @ 4omhs and 250@ 2omhs. The specs for the sub are 150 rms @ 4omhs. They don't sound as loud and would like to get out as much of it as possible. I had this set up in a truck previously. Would it be better to get a bigger box for the sub? If I do get a bigger box, should I get ported or sealed? I listen to all types of music ( rap, rock, Spanish). Or could i add another kicker comp sub with the same specs and a dual box? Also how big of an amp can I put on 8 Guage wiring? Thank you!

    I just purchased a HO-110-w6v3 subwoofer/enclosure from Crutchfield. I've tried doing a lot of research for powering the sub which handles 600W RMS at 2 ohms. I already owned a JBL GTO-751EZ amplifier which puts out 750W RMS at 2 ohms. I know this article says it would be safe to power the sub with that amp because of the 75%-150% range, but I really don't want to damage the sub and I'm nervous about setting the gain properly. My buddy owns a SMD-DD1 distortion detector that I could use to set the gain of the amp but wouldn't that put maximum power (without distortion) to the subwoofer? Should I use Ohm's Law instead, to put the proper voltage to the speaker from the amplifier so it is only getting 600W?

  • Buck Pomerantz from Crutchfield

    Posted on 10/13/2015

    Leo, If 150 watts RMS to a sub rated for 150 watts isn't loud enough, you need another sub and a stronger amp. 8-gauge power wiring will support up to about 350 watts of amplification. Your choice of a ported or sealed enclosure entirely depends on your taste for bass. Check out Sealed or ported for help in deciding.

  • Buck Pomerantz from Crutchfield

    Posted on 10/13/2015

    Drew, If you want to set the gain of your amplifier so that it can only put out up to 600 watts RMS clean, then, after disconnecting your sub and playing a 40 or 60 Hz, 0 dB test tone, set the gain so the output voltage reads 34.6 VAC RMS on a multimeter.

Or is that amp to powerful for that single sub? Also if that amp is indeed to powerful would the GM-D8601 be a better fit with a 500 x 1 @ 2 ohm output? Trying to plan ahead if I ever decide to get a second sub so I would really prefer the GM-D9601 for the versatility to add to the system if decide to do so. Thanks

  • Buck Pomerantz from Crutchfield

    Posted on 11/10/2015

    Matt, That amplifier and subwoofer make a great match - just be sure to set the amp's gain so that the sub never distorts. Then, when you add the second sub, you can wire it with the other gear like this. The amp is stable for the 1-ohm load and will be able to put out up to 1200 watts RMS, 600 for each sub.

    Jake, I assume you're in Australia. Unfortunately, we're only licensed to sell gear in the United States and Canada. I don't even know what car stereo equipment is available in your country. An online search ought to bring up at least one car audio dealership somewhere near you. Look for a mono subwoofer amp, with a subsonic filter, that can put out between 600 and 1200 watts RMS at 2 ohms.

  • Buck Pomerantz from Crutchfield

    Posted on 12/31/2015

    Justin, Even without knowing the exact subwoofer you have or how it's wired to the amplifier, I can say that clipping is usually the result of an improperly set gain. If you continue sending a clipped signal to your sub, it will burn out. Check out this article for help on how to set amp gain properly.

    Jose, Not knowing exactly what amplifier or subwoofers you have make it impossible to give advice on how to wire them together. Kicker Comp subs come in SVC 4-ohm and DVC 4-ohm models. Sony makes a few amps that claim to make 1000 watts. If you want a question answered about your system, you must identify your equipment by model numbers as well as brand names.

  • Randy Bagby from kokomo

    Posted on 1/30/2016

    I read through your "how to match subs to an amp" and can't believe a company the size of yours with the resources you have, have it so wrong. Wattage ratings on subwoofers are virtually meaningless. How much power a sub will handle and perform with is solely dictated by the excursion demands imposed by the enclosure. As long as you're not exceeding the mechanical limits of the driver you can basically give it as much power as you want. The more headroom the better. We listen to music, which is dynamic, so your sub will never see maximum power for more than split seconds. The only way to know how much power you need is to model the driver into an enclosure using the T/S PARAMETERS, but no mention of those whatsoever. Anything else is just a guess. Maybe an educated guess, but proper modeling takes 100% of the guesswork out of the equation. It's not hard, but it's the CORRECT way you should be educating people. Going by your recommendations my pair of 8"subs rated at 130w each should be on an amp of about 400w, but I know that in the enclosure they're in exactly what frequency they will exceed x-max and the db level that will occur, and they will handle just over 1000w. But in an IB configuration they will exceed it with less than rated power. What you're teaching will generally work, but why not teach people the CORRECT way to do things from the beginning.

  • Buck Pomerantz from Crutchfield

    Posted on 2/1/2016

    Randy, If we were to include in the article the information you discuss, 99% of our customers would not understand it, and so the article wouldn't help them very much with matching subs and amps. The subject's complicated enough. One thought they might walk away with would be your statement that: "As long as you're not exceeding the mechanical limits of the driver you can basically give it as much power as you want." Only understanding the second part of that sentence, most people would blame their blown drivers on bad advice, and want warranty replacements or repairs. Reputable subwoofer manufacturers not only rate each of their products with a specific and useful RMS power rating but also state what kind of enclosures it will work in. If someone goes ahead and installs a sub in an infinite baffle (IB) arrangement that it wasn't designed for and blows it giving it its "rated power," they themselves would be responsible for the mis-application and damage, and wouldn't receive any warranty consideration. A sub designed to work in free-air or IB setups will be guaranteed to safely work at its rated RMS level.

    Posted on 3/11/2016

    Hello, and firstly let me thank you for the wealth of information your site, and this thread in particular have provided me. I am looking to purchase 2 of the pioneer shallow mount 10" woofers (TS-SW2502S4) rated 300w/RMS (1200max) @ 4ohms. I intend to run them with a pioneer GM-D8601 rated 300w@4ohm, 500w@2ohm, or 800w@1ohm (all RMS). My question is; what would be the proper way to wire this amp for 1ohm allowing 400w RMS to each woofer, given that this amp has outs for 2 speakers already (+-.+-) not simply one set of outs (+-). Or would it be best to simply wire each woofer to each output, and would that essentially be running each at 2ohm (250w each speaker)? The two sets of outputs has me confused a bit I suppose. Thanks again for your help!

  • Buck Pomerantz from Crutchfield

    Posted on 3/11/2016

    Chris, Those subwoofers are SVC (single voice coil) 4-ohm subs and two of them can only get wired together as an 8-ohm or a 2-ohm load. That mono, 1-channel amplifier has two sets of speaker output terminals, wired together inside the amp, for convenience, and if you hook a speaker to each terminal it would result in the two speakers being wired in parallel, cutting the total impedance in half. For your set-up, that's exactly what you can do: Wire a 4-ohm sub to each terminal, and the amp sees 2 ohms as its total load. It's electrically the same as in the diagram in the link.

    John, Just because an amplifier can put out 500 watts doesn't mean you have to always play it that loud. You should be fine using that amplifier with that subwoofer, as long as you set the amp gain low enough to never distort the sub's sound.

  • John from Sooke

It is a switchable 1 or 4 ohm model...not sure if its svc or dvc... 1. can i match this sub with a current model such as the kappa 100.9w 2. will my amp have the power to drive both and how should it be set up. 3. Ported or sealed box...its going into a trunk.

    Ryan, Those two subwoofers will work together just fine. Set both their switches to 4-ohms and wire them to that amp like this diagram. In this configuration, the amp will be able to put out 600 watts RMS total, 300 to each sub. As for ported versus sealed enclosures, that's a choice you'll have to make based on your tonal preferences and the style of the music you listen to. Check out this article for help deciding that.

    I have 2 sundown audio E10's 500 watt RMS and a oxygen audio air t700. Would this amp be good for these sub's?

  • Buck Pomerantz from Crutchfield

    Posted on 4/22/2016

    Tyler, I can't recommend wiring together gear I'm unfamiliar with which Crutchfield doesn't carry. In order to tell if that amp will run those subs successfully depends on the subs' coil configurations, impedance, and RMS power rating - and I can't find that information even with a web search. Perhaps you could contact the vender you got your gear from and find out their specs.

  • Buck Pomerantz from Crutchfield

    Posted on 6/6/2016

    Greg, An amp like Alpine's MRX-M110 would be able to supply those two 400 watts RMS rated subs with 800 watts RMS total, a perfect power match. Wire them like this diagram.

    Buck, thanks in advance for any advice you can offer. I have a RF Prime 300.4 amp with a build sheet rating of 403 watts. What I want to do is run two rear 6.5 speakers off my head unit and run the door 6.5 speakers from two channels of my amp, with a sub (10in ?) off of the other two amp channels bridged. I looked at the wiring diagram in my RF manual and it looks like I will need a SVC 4 ohm sub. But at what power rating will the sub need to be? 200W?

  • Buck Pomerantz from Crutchfield

    Posted on 6/13/2016

    Jimmy, Look for a SVC 4-ohm sub or a DVC 2-ohm sub (wired like this) rated between 100 and 200 watts RMS. Rockford Fosgate's R2SD2-10 shallow-mount sub might be perfect for you.

    I received a 10" 400W Kicker CompRT, will my Kicker amp that does 300w X 1 @ 2ohms be OK for it ? Are the 300w achieved at max gain setting on the amp or will I have to tune it to 300W?

  • Buck Pomerantz from Crutchfield

    Posted on 6/30/2016

    Felix, Not knowing exactly which subwoofer you have makes it impossible to give advice on how to wire it. Kicker makes 10-inch CompRT subs in a DVC 1-ohm and a DVC 2-ohm model. If you want a question answered about your system, you must identify your equipment by model numbers as well as brand names. As for amp gain, it is not for achieving maximum output. It is to match the input sensitivity of the amp to a receiver's output. Check out this article for help setting amp gain.

    You would think a company the size of crutchfield would employ engineers that know how this works and give proper answers. Quite frankly, I have lost respect for your company. The amount of power a subwoofer cab handle is dictated by excursion demands imposed by the enclosure. The only way to know is to middle it using the T/S PARAMETERS and a good modeling program. In reality, subwoofer wattage ratings are the most worthless spec the company gives you. Who cares how much heat it can handle, we listen to music, which is dynamic. A driver in a small sealed box might take 3X's it's rated power to achieve x-max whereas the same in an IB alignment may pass it's mechanical limits on a third of what the company recommends. All you're doing is guessing at what might work, but have absolutely no way of knowing without knowing what enclosure the driver is going in. Please research this subject do you can inform your potential customers the correct way to pick an amp.

  • Buck Pomerantz from Crutchfield

    Posted on 7/6/2016

    Randy, It sounds like you know a lot about subwoofers, but probably not so much about customer service and warranty returns on products, which is what those power ratings are for. That's one reason you've resubmitted this comment from one you made last January. I urge you to reread my answer to you from then - it still applies.

    Posted on 7/7/2016

    I was wondering what amp I needed if I were to buy two JL Audio 12TW3-D4 12" 400W Dual 4 Ohm thin-line subwoofers. I did the math on 75%-150% of 800watts RMS and it's 600-1200 watts rms for the amp but I don't know what amp to get. Does the amp need to be a 4ohm amp with 1200 watts rms? Or anything in between 600-1200 watts rms? If it's a 900 watt rms amp will I not get the full power of my subs?

  • Buck Pomerantz from Crutchfield

    Posted on 7/7/2016

    Josh, You're correct as to how much power you'll need for that pair of subs. The other part of the equation is at what impedance does this power need to be delivered through? Two DVC 4-ohm subs can only get wired together to form a 16-ohm load, a 4-ohm load, or a 1-ohm load. So, you'd get an amplifier that can output 600 to 1200 watts RMS at one ohm or at four ohms. Check out Pioneer's GM-D8601. It could feed those subs a total of 800 watts RMS, 400 each, which is exactly their top RMS rating.

  • Josh from San Antonio

    Posted on 7/9/2016

    Hey Buck, thanks for helping me out but I have one more question. Someone said on another thread, "IF you connected a sub running at 8 ohms, to an amp running at 4 or 2, the resistance would be great and the amp would run hot. When this happens it over heats and eventually shuts down resulting in returns. If the amp is running at 4 ohms and the sub is running at 1 or 2 then the sub gets pushed harder to compensate and the voice coils will generate more heat and lock up." If I use the two 400watt rms 4ohm subs with a 1ohm amp, will I be pushing the amp harder or do the subs get turned INTO a 1ohm load, by wiring them how you said, and then become equal when connected with a 1ohm amp? I just don't want to burn/blow anything up since there is a lot of money involved.

  • Buck Pomerantz from Crutchfield

    Posted on 7/11/2016

    Josh, That someone on another thread is spouting absolute nonsense, and has confused your situation. For instance, if you connect an 8-ohm sub to an amplifier, the amp sees an 8-ohm load, and can't be "running at 4 or 2" like that person said - that's impossible. Subwoofers have impedance, measured in ohms, and are the "loads" the amp "sees" on its output. Amplifiers output different amounts of power (watts) through different impedance loads.

  • Felix M Medrano from San Antonio

    Posted on 7/18/2016

    Josh.... That guy couldn't be more wrong. An amps impedance rafting, means if you run an sub impedance below that rating, it's no bueno for the amp. You can run a higher impedance, but it's optimal to run an impedance that matches the amps rating to reach its true RMS rating..

  • Buck Pomerantz from Crutchfield

    Posted on 7/18/2016

    Jaeden, Although that amp is capable of overpowering that sub, you should be alright as long as the amp gain is set low enough to never allow loud distortion to play.

  • Sal G

    Posted on 7/21/2016

    the complicated thing about selecting/wiring an amp is finding out where the amp is more stable, at a given impedance (load), without making the amp "clip". one reason why I don't like having an amp 'run' with an 1-ohm load

  • Buck Pomerantz from Crutchfield

    Posted on 8/1/2016

    Josh, Two 1000 watts RMS rated DVC 4-ohm subs, which can only get wired together to form a 16-ohm, a 4-ohm, or a one-ohm load, will be best driven with an amplifier that can put out anywhere from 1500 to 3000 watts RMS at one ohm or four ohms. The Rockford-Fosgate-T2500-1bdCP would work great for those two subs, being able to put out 1500 watts RMS in the 4-ohm configuration and 2500 watts RMS in the 1-ohm setup.

    Brandon, A great amplifier for your SVC 2-ohm 250 watts RMS rated Rockford Fosgate sub would be an amp that can put out 250 watts RMS at 2 ohms, like the Rockford Fosgate Prime R250X1. If you get it from Crutchfield, you'll save 25% on the wiring kit when you purchase that along with the amp.

  • Buck Pomerantz from Crutchfield

    Posted on 9/14/2016

    Hello! I am looking to add an amplifier and sub to my existing stock audio system. It currently has an Alpine 6 speaker setup with a 276 watt amplifier. I was thinking about going for the Alpine SWR-12D2 (Type-R 12" subwoofer with dual 2-ohm voice coils) but am not sure which amplifier to go for... I'd like to keep it all Alpine and so far I see the following options for amplifiers: - Alpine MRV-M1200 - Alpine PDR-M65 - Alpine MRX-M110 - Alpine MRV-M500 Would the MRV-M500 suffice or would you suggest going in for another amp? Appreciate any insight you can provide into this! Regards, Randal

  • Buck Pomerantz from Crutchfield

    Posted on 9/29/2016

    Randal, For that sub, the MRX-M110 would be the best choice of the ones you mention, able to send the 1000 watts RMS rated sub 800 watts RMS when wired as a 1-ohm load. Even better, an Alpine PDX-M12 could send it 1200 watts RMs when wired as a 4 ohm load.

  • Buck Pomerantz from Crutchfield

    Posted on 10/12/2016

    Corey, When two 4-ohm loads get wired together in parallel the subsequent total load becomes 2 ohms. That amp cannot safely drive a 2-ohm load with bridged channels - it'll probably overheat and shut down. I'd say the safest way to wire that gear together is to connect each sub and speaker to its own channel of the amp.

    Cyrus, Any mono amplifier that can put out between 450 and 900 watts RMS into a two ohm load will work, but I think this cool little Kicker CXA600.1 would work great. Its 600 watts RMS output matches exactly the rating of that pair of 300 watts RMS rated subs.

  • Buck Pomerantz from Crutchfield

    Posted on 10/20/2016

    Chase, Your best strategy, in my opinion, is to rewire your subwoofers to 4 ohms so your present amp can handle them safely. Then, you can look for a more powerful amp, one that can do from 300 to 600 watts RMS at 4 ohms, like JBL's Club 5501 subwoofer amplifier.

  • Buck Pomerantz from Crutchfield

    Buck, i have recently purchased a Rainbow Dream 4 Channel Amplifier. I plan to run a pair of components at the front, and bridge the remaining 2 channels to run a sub - until I can afford a mono amp. The Rainbow amplifier can run 4 channels at 90w per channel at 4 ohm, and 130watt at 2 ohm. What is the the bridged channel rated at? What subwoofer could i run off this? Thanks in advance,

  • Buck Pomerantz from Crutchfield

    Posted on 11/8/2016

    Jordan, Rainbow Audio claims that that amp can put out 250 watts when bridged into a 4 ohm load, but doesn't say if that's a peak or an RMS spec, so I'd be a bit skeptical as to its true output capability. You'll probably be safe using a 4-ohm single voice coil sub rated for about 250 watts RMS, like an Alpine SWA-10S4.

  • Buck Pomerantz from Crutchfield

    Posted on 12/9/2016

    Cole, The best that amp can do, according to its specifications, is 625 watts RMS bridged to a 4-ohm load. So, you'll look for a subwoofer that can get wired as a 4-ohm load and is rated for between 418.8 Watts RMS and 831.25 watts RMS, like an Alpine SWS-10D2 10" sub wired like this.

    Posted on 12/19/2016

    Anthony, The shakers' output depends on how you have them wired to the amp. And you should know that that amp puts out about 250 watts RMS a channel and that the shakers don't really make noise at all. Most people use them in conjunction with an existing sound system to add kick. But maybe I'm misunderstanding your application.

    I have a Kicker 43VCWR122 which is a single 12" 2 ohms rated at 500W rms. The amp i have is a pioneer GM-A5702, which is a 2-channel amp, 240w @2 ohm x 2, or bridgeable to 480w @ 4 ohm. My question is, is it possible to wire that sub to only 1 channel at 240w @ 2 ohms. If that is possible, is there a risk of damaging either the amp or sub?

  • Buck Pomerantz from Crutchfield

    Posted on 12/29/2016

    Jitendra, Not knowing exactly what amplifier or subwoofer you're referring to make it impossible to give advice about them. If you want a question answered about a system, you must identify the equipment by brand names and model numbers, although I'm probably unfamiliar with the products available in your country.

  • Buck Pomerantz from Crutchfield

    Posted on 12/29/2016

    Chris, Yes, you can use just one channel of that amplifier. Leaving a channel's input and output disconnected will cause no harm to the amp or sub.

    Nick, For that subwoofer you should look for an amplifier that can put out between 375 and 750 watts RMS into a 2-ohm load, like a Pioneer GM-8601.

  • Buck Pomerantz from Crutchfield

    Posted on 1/2/2017

    John, If those specs are correct, you should be okay wiring that gear together. We recommend powering subs with 75% to 150% of their total RMS rating, and this amp certainly fits that criteria. Just make sure you set the amp gain so no distortion ever plays.

  • Buck Pomerantz from Crutchfield

  • Buck Pomerantz from Crutchfield

    Posted on 1/18/2017

    Jessica, That amplifier will work with that sub wired this way. Make sure you set the amp gain so no distortion ever plays. And don't expect very loud bass - judging by the size of the onboard fuse, that amplifier's power specs are a bit exaggerated.

  • Matt Thompson from Washington DC

    Posted on 1/19/2017

    Hello. I have two subs. 1,200w, 400w rms, 4 ohms impedance each. I have a Rockford P300-1. I'm a slightly confused on the proper paring of subs to amps. I bought this set up from Let Go. I feel like my subs are severely underpowered. What do you recommend?

  • Buck Pomerantz from Crutchfield

    Posted on 1/19/2017

    Matt, That amplifier can put out 150 watts RMS into 4 ohms and 300 watts RMS into 2 ohms - not enough power for one of those subs, much less two. Two single voice coil (SVC) 4-ohm subs rated for 400 watts RMS would be happy with an amplifier that could put out from 600 to 1200 watts RMS at 2 ohms, like a Pioneer GM-D9601.

  • Jessica from Baytown

    Posted on 1/19/2017

    Referring to my comment on 1/17, What amp would you recommend for those subs? I also have a Power Acoustik RZR1-2500D amp.

  • Buck Pomerantz from Crutchfield

    Posted on 1/20/2017

    Jessica, That amp will probably work with your sub, wired the way the link I provided shows. Again, judging by its fuse complement, the amp will probably put out about 375 watts RMS at 4 ohms, which will be fine for the sub. Just set the gain so no distortion plays. Another option would be getting a Pioneer GM-8601.

  • Buck Pomerantz from Crutchfield

    Posted on 1/29/2017

    Jesus, Two DVC 4-ohm subs rated at 600 watts RMS each would be well-driven by an amplifier that can put out between 900 and 1800 watts RMS at either 4-ohms or 1-ohm, like a Pioneer GM-9601. You'd wire them together like this.

    Shane, I can't figure out what subwoofers you have from the model number you've given. That amplifier, which can put out 175 watts RMS at 4 ohms and 275 watts RMS at 2 ohms, will probably only have enough power to run one sub.

  • Buck Pomerantz from Crutchfield

    Posted on 3/6/2017

    Todd, In spite of its specs, that amplifier will probably only be able to supply about 65% of the power those subs would like. But it may be enough for you. I doubt you'll need a capacitor with this setup.

  • Buck Pomerantz from Crutchfield

  • Buck Pomerantz from Crutchfield

    Posted on 3/9/2017

    Joshua, You have a potential 3000 watts RMS going to an 800 watts RMS sub system, that's why the subs blow. If you want a question answered in more detail about your system, you must identify the equipment by model numbers as well as brand names.

  • Buck Pomerantz from Crutchfield

    Posted on 3/9/2017

    Todd, Your two DVC 4-ohm 600 watts RMS rated subs will work best with an amplifier that can put out between 900 and 1800 watts RMS through a 1-ohm or a 4-ohm load, like a Rockford Fosgate R1200-1D.

Is the amp capable of supporting both the 4ohm load on the speaker channel and the 2ohm load that the subs would create simultaneously? Or do i need to get DVC subs? Or can i just to some wiring trickery to drop the impedance of the speaker channels use?

  • Buck Pomerantz from Crutchfield

    Posted on 3/17/2017

    Anthony, No wiring trickery will be necessary in your setup. That amplifier was designed to work in exactly the configuration you describe - one speaker per full-range channel and a subwoofer load as low as 2 ohms on the sub channel.

  • Buck Pomerantz from Crutchfield

    Posted on 3/20/2017

  • Buck Pomerantz from Crutchfield

    Posted on 4/5/2017

    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 just fine.

    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.

    Posted on 4/12/2017

    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.]

  • Buck Pomerantz from Crutchfield

    Posted on 4/24/2017

    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.

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!

  • Buck Pomerantz from Crutchfield

    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.

  • Buck Pomerantz from Crutchfield

    Posted on 5/5/2017

    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.

  • Buck Pomerantz from Crutchfield

    Posted on 5/15/2017

    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.

    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.

    Posted on 6/5/2017

    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.

    J, Two SVC 4-ohm subs rated for 200 watts RMS each will sound best with an amplifier that can put out between 300 and 600 watts RMS at 2 ohms, like a JBL GTX500, wired like this diagram.

    hello... im having a subwoof with rms 300 , rear 2 speakers of 100 rms each and another 2 speakers for the front dash with 60 rms each, so the total is 620 RMS to the whole. what kind of amplifier with RMS is needed to power all these speakers without distortion ?

    Vikram, Driving four speakers and a sub takes a 5-channel amplifier, like a JBL GTR-7535.

    I have sony xm gs100 class d amplifier. Am planning to hook this amp in my home.how I will power the amp?(how much volt and ampire) And which type sub woofers shall I use ?( Svc or Dvc ) and Rms power of sub an ohms?

  • Buck Pomerantz from Crutchfield

    Posted on 6/27/2017

    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.

    I have a Alpine SWR-10D4 Type-R 10" subwoofer with dual 4-ohm voice coils. What specs of an amp should I get to work with this sub?

  • Buck Pomerantz from Crutchfield

    Posted on 6/29/2017

    Phia, A DVC 4-ohm sub rated for 1000 watts RMs will sound best with an amplifier that can put out between 750 and 1500 watts RMS at 2 ohms, like a Kenwood KAC-9106D.

    I have 2 Harmony Audio HA-F104 subs. They are 350 rms each, so 700 total, and each is a single coil 4-ohm. What size amp would be best for this set of subs?

  • Buck Pomerantz from Crutchfield

    Posted on 7/3/2017

    Triston, Two SVC 4-ohm subs rated for 350 watts RMS each will sound best with an amplifier that can put out between 525 and 1050 watts RMS at 2 ohms, like a Pioneer GM-D9601.

  • Sikholiwe from Cape Town,

    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

    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.

    Could you please tell me the best amplifier compatible with a JL Audio C5-525cw intended for each back door? I saw something called the Pioneer GM-A5702, but I wasn't sure

  • Buck Pomerantz from Crutchfield

    Posted on 8/4/2017

    Jesse, That amp can put out twice the power ratings of those speakers and will probably blow them. You'd do better with an amp like the Pioneer GM-A3702.

    Jake, Two SVC 4-ohm subs rated for 300 watts RMS each will work best with an amplifier that can put out between 400 and 800 watts RMS into 2 ohms, like a JBL GTX500.

  • Buck Pomerantz from Crutchfield

    Posted on 8/14/2017

    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.

    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.

  • Buck Pomerantz from Crutchfield

    Posted on 8/24/2017

    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.

  • Buck Pomerantz from Crutchfield

    Posted on 8/24/2017

    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.

    Hey Buck, I have Hifonics Zeus 1200 watt Mono D class 1 Ohm amp, and was wondering what type of subs would be a good fit for this amp? I'm trying buy two 12" subs for the pro box I already have so there is some more info if that helps.

    Hey Buck, I have a Memphis 750 watt amp at 2 ohms on a mono block. Any recommendations on subs to achieve max performance?

  • Buck Pomerantz from Crutchfield

    Posted on 9/5/2017

    Zack, An amplifier that can put out 1200 watts RMS at 1-ohm would be a great amp for two SVC 2-ohm or two DVC 4-ohm subs rated between 400 and 800 watts RMS each. In your case, you'll also have to match the subs to your enclosure's cubic capacity or interior volume. Why don't you give Crutchfield a call so an Advisor can help you choose the right subs for your amp and box.

    Josh, An amplifier that can put out 750 watts RMS at 2-ohms would be a great amp for a SVC 2-ohm or a DVC 4-ohm sub rated between 500 and 1000 watts RMS, or two SVC 4-ohm or two DVC 4-ohm subs rated between 250 and 500 watts RMS each.

  • Buck Pomerantz from Crutchfield

    Posted on 9/18/2017

    Carl, This diagram is a good starting place. In your case the 4-channel amp would be replaced with your 5-channel amp, and the sub's speaker wiring added.

  • Buck Pomerantz from Crutchfield

    Posted on 9/22/2017

    Adam, That amp's highest output is 750 watts RMS. It'll achieve that if it's wired to a DVC 4 ohm or SVC 2 ohm sub rated between 500 and 1000 watts RMS.

    Hey Buck, I have a quick question.. I bought a 12" sub that it's peak power is 2200 Watts & it's 4ohms.. I was thinking of buying a hifonics 2400watt amp but it's like 1ohm I don't really know much about Music so I need some help.. If you need more info on the amp it's the Hifonics Brutus BRX2400.1D! Please help bro

  • Buck Pomerantz from Crutchfield

    Posted on 10/10/2017

    Wesley, A peak power specification is useless when designing a system - you should only use RMS power specs. If you want a question answered about your subwoofer, you must identify it by brand name and model number.

  • Wesley from Bronx

    Posted on 10/10/2017

    Buck I'm back. So my sub is a AudioPipe TXXBD412. It is 2200 Watts peak & 1100 RMS watts. Also 2 x 4 Ohms Voice coils.. will I be able to match this with a Hifonics Brutus BRX2400.1D? The RMS for the Hifonics Amp is as follows: RMS: 850W x 1 @ 4 ohms, 1600W x 1 @ 2 ohms, 2400W x 1 @ 1 ohm Thank you!!

  • Buck Pomerantz from Crutchfield

    Posted on 10/10/2017

    Wesley, That amp will work with that sub just fine, wired like this. Just be sure to set the amp's gain so no distortion ever plays.

    I have a kenwood bp-210, two 10" subs. I was wondering if a kenwood kac-501 mono 1000w amp, 300 W x 1 x 4 Ohms; 500 W x 1 x 2 Ohms would be compatible?

  • Buck Pomerantz from Crutchfield

    Posted on 10/15/2017

    Tyler, That amplifier will probably blow that subwoofer to smithereens - it's three times more powerful than the sub's power rating. For running that sub, look for an amp that can put out between 75 and 150 watts RMS at 4-ohms, like a Rockford Fosgate R150X2 bridged to one-channel mode.

    Hi, I'm going to buy 2 of these subs: JL Audio Thin-Line 10TW3-D4 shortly. Can you recommend a good amp handles the 400rms X2? Would like to go real close to their limits. Thanks in advance.

  • Buck Pomerantz from Crutchfield

    Posted on 10/20/2017

    Krisztian, Two DVC 4-ohm subs will work best with an amplifier that can put out between 600 and 1200 watts RMS at 4-ohms or 1-ohm, like a Pioneer GM-D8601.
