The best option since the T600 is not 2ohm brigeable is to run each amp stereo at 2ohms with each DVC sub running in parallel (making 2ohms per sub) that wil give you 300WRMS per sub and still be the same as running the amp bridged.. Do you mean 4 speakers or 4 pairs of components?? If 4 speakers you can run them stereo at 4ohms giving you 60wrms per channel or bridge, if you have 4 pairs you can do the same jsut with 2 amps. Should be a really nice setup.. Make sure you get the correct guage wiring 2or smaller for so much power and with that much wattage you will need some capacitors (2 farads) as youll be runnig about 1600+ watts and needing a 160amp alternator just to run the amps properly + whatever is needed to run the car so hope you have some extra cash set aside and a second battery wouldn't hurt or upgrade your stock to an Optima yellow top. Keep in mind your system is only as good as its installation so don't skimp on accessories as they are of just as much importance as the subs/amp/radio...good luck on the install. Post some photos when your done..

Hi i have apioneer ts-w2501d4 sub and i am running it with a vibe a7 slick 1300 watt amp and doesnt sound well ,.what is the problem?is it the amp>?.and can you tell me as well which enclosure box is...


ported enclosures are for spl only using these will be louder on certain frequencies but can sometimes not play others at all. i say if you want it loud go ported if you want clarity go with sealed. and you have to look at the manual of the sub it self. each sub has a desired volume of air that it wants for the best sound. my subs like to have around 1 cubic foot of air per sub. that might be a good spot to start. but me personally it sounds like you might have your gains set high so your amp is making a static sound which will change the pitch of the sound. and also i prefer a sealed box but thats your choice.

We are trying to make a custom fiberglass kick panels for a truck


Hello kpauten,

Here's a link to an excellent fiberglass forum which includes builds or subwoofer enclosures, kick panels, and other audio enclosures.

There's probably one or more similar to what you have in mind.

Check this link for a materials list and some fiberglassing specifics. The build was a subwoofer box, but the information and procedures should be helpful.

Look at these custom enclosures. They take up minimal cargo space, look good and sound great.

I need an enclosure for a power acoustik mofo 12''.


Hello miles_jamike,

Power Acoustik recommends a 1.25 CuFt sealed and 2.0 CuFt ported enclosure for the P1, P2 and P3 subs. The PSQ needs 1.25 sealed and 1.75 ported. In physical size, this translates into about 16X12X14 for sealed and about 30X42X15 ported.

You should try to stay pretty close to the recommended enclosure volume for best performance. A good volume calculator is located here on the12V.com website. Just enter the proposed width, height, depth, and material thickness and click the "=" to get the CuFt.

If you are building (or having built) a custom enclosure for a specific location in your vehicle, all you need to do is stay very close to the volume recommended.

If you intend to purchase a generic enclosure, the Goldwood shown here at Parts Express is an exact fit. Atrend also makes good generic enclosures, their model 12SAL in a sealed box with 1.20 CuFt and the 12LSV ported with 2.50 CuFt would be good choices.

Crutchfield has both generic and custom enclosures made by JL, MTX, QLogic, and Bass Slammer. Crutchfield has excellent support. They will respond promptly and positively to your phone or email inquires. If you have never ordered from them, you can use a "friend referral code", such as mine, which is: p7sdj-hrx8q-9800g, and on any order of $200 or more, you receive a $20 discount. And I get a $20 credit on a future order. Also, many orders qualify for free shipping.

Hope this helps.

Bass sounds muddy and volume is minimum.


Hello mercedesman4,

Your setup sounds great. I had to settle for Blaupunkt in my Mercedes.

It sounds like the culprit is your enclosure. It's possible that by tweaking the settings, you could improve the sound somewhat, but having been used to the sound of a sealed enclosure, maybe not. Sealed enclosures tend to produce tighter, more accurate bass and have a flatter frequency response curve. They are also generally the enclosure of choice when looking for a SQ (sound quality) oriented setup.

Ported enclosures will produce louder bass than sealed enclosures, and maybe that's why some audio guys push them. They also allow the speaker to operate more efficiently, so you need less amp power for a given volume. Higher tuning on a ported box will get louder, but at the expense of sound quality. Lower tuning will still get louder than a sealed box, and the sound quality will be better than a box tuned higher, but still not as good as sealed. That's what I meant about tweaking the settings. You may see some improvement by setting the crossover lower, decreasing bass boost, or by turning the subsonic filter on/off. I'm no audiophile, but personally I've never been able to stand the sound of a ported enclosure, however it was tuned. Sealed just sounds better.

Hope this helps.

Need specs on a ported box for 1 12"stroker 124


I used to be a Cerwin Vega dealer. How much space do you have? Ideally you would want at least 4 cubic feet per sub. If you shoot me an E-mail @ dynami28@charter.net I will be willing to discuss exact plans for your application. I now run a local business designing custom enclosures and electronics for home, marine, and auto. As for your Stroker- A general box design is going to need to be ported with alot of volume (cubic feet) the bigger the better. The actual port diameter and length will be determined after I have some basics from you. I will give you a free design to start with if you Email me the specifics like how much room do you have? how much power? dual 4ohm coils? car, p/u truck, van/suv? The more info the better. If you want something more custom please specify and I will be happy to help.

I just bought 2 JVC CS-DX30 12" car speakers. What kind of box am I supposed to get sealed? vented? ported?


You can put these in either a sealed or ported enclosure, not vented. Your box choice depends on what kind of bass you are looking for and the power of the amp you use to drive them.

A sealed box will give you more accurate bass reproduction but will require more power for a given volume. A ported box will be louder at the expense of sounding somewhat "boomy". You should really listen a pair of 12"s in each type of box before you make your decision. Some people don't like the sound of ported enclosures, others love it.

I'd recommend one of the enclosures here:

Choice of speaker box


If you're looking for SPL (LOUD) go vented.
If you're looking for tonal accuracy (Sound Quality) go sealed.

The tradeoff between the two is that a ported enclosure will allow your subs to play highly powered. More air flow - better cooling of the voicecoils.

Sealed enclosures dont like much power because the coil cannot breathe and heats up rather quickly.

Its up to you, and your listening type.
Just remember LOUD = PORTED
QUALITY = SEALED

Bandpass is kind of a mixture of the two, however you give up some of the frequency range the sub plays at - and I dont ever recommend a bandpass enclosure to my customers unless they are looking to be flashy and light up the cones or magnet assemblies.

There are advantages and disadvantages to every enclosure type.
Pick the one that best suits your taste, and be sure to fire it toward the rear of the vehicle for the best response and cabin gain.

Thanks for using FixYa - a FixYa rating is appreciated!!

Finding a good box for the sub


< I design sub enclosures for a living so you are in luck. > The one thing to remember is that generic sub boxes are just that - generic. Even if they have a fancy brand name, unless they are built for the sub you are using you will be making a guess as to how well it works. Don't get me wrong though it may work well in that band pass box, but just imagine how much better it could sound in a custom enclosure. Having said that you have the right idea, and bandpass enclosures can be power-full. If you send me (dynami28@charter.net)
the specs that came with the sub I can give you an idea of what kind of box you should get or, if you want to build your own, I can do the specs on that too. Personally I stay away from bandpass enclosures for one reason. When the subs distorts or gets pushed too hard you can't hear it happening. Since the sub is completely enclosed it's somewhat muffled or insulated so that distortion is hard to hear, which can blow up subs. A good ported enclosure would do well and basic plans should be on Lanzar's website, or available from myself. I do not recommend a sealed enclosure unless these subs will see light duty and you don't expect ground shaking bass. They can sound okay in a sealed box but most car audio enthusiasts like the ported boxes for their increased output and lower tones. Email me if you can't find the specs on those subs I might still have them on file. (Also the enclosure should be at least 3/4" thick MDF with bracing throughout.)

You should be able to download the owners manual for these speakers. The manufacturer will give detailed specs. on the type and dimensions of recommended enclosures for this particular speaker. If nothing is available to download, you could try to contact the manufacturer directly.
