In order to sound good, there are a lot of specifications that have to be considered when getting a speaker enclosure. You have to know the size, depth, displacement, SPL and other factors on the speaker, then you have to match it to the height, width, depth and porting of the box. So if this was not done, you will have muddy sounding audio.

SOURCE: how can i bridge a mtx 9500 using a mono amp?

You cant bridge it to the MONO AMP . You can only bridge subs & speakers to 2 CH & 4 CH AMPS that are bridgeable. Because if it appears that there is 2 channels on a Mono amp its so its convenient for you to hook up 2 4ohm subs to it easily But both channels are actually connect internally together in parallel inside the amp unlike a 2 channel they are separate.

So just connect your mtx 9500 to a plus and a minus and doesnt matter which since all the + terminals of are connected together and - are connected together already.

Whats important is on the side of the sub/box it reads 2 ohms. The lower the ohms the more power the Mono amp will put out. Mono amps are designed to handle 2ohm loads.

If it reads 4ohms The MONO amp is the wrong amp to use cause the power will be weaker. So if you have a 1000 Watt Mono amp at 4ohms the sub will only get 500 WATTS Max while a 2 ohm will get the full 1000 Watts.

If it reads 4 ohms connect it to a 2CHANNEL AMP and BRIDGE IT (connect + of the sub to 1st channels positive of the amp then connect - of the sub to 2nd channels negative of the amp) . The power will be doubled when you bridge it on a 2 channel amp. NOW if it was a 2 ohm sub and you bridged it to the 2 channel amp it will fry the subs and ruin the amp. 2 CHANNELS CANT TAKE A 2OHM LOAD BRIDGED OK.

I have 4 mtx 9500 12in subs 2 of them is on a mtx 92001 and the other is on a mtx 4001d . would it be better to run all four on the mtx 4001d. for more power and a better sound or how should i run this set...


NEVER mix different power amps. Depending on the ohms of your subs, sell one of the amps, up to you. The 4001 has more power, but either amp will do the job, the amp needs to see a 1 ohm load, so your subs have to be dual 2 ohms, or single 4 ohms to do this. If your subs are dual 4 ohms then you will have to run your amp at 2 ohms which would be have the power, or a half an ohm, (Not Recomended) and be at double the power. You may be able to do a competion sound off and just "Burp" the subs, but at a half an ohm, dont expect to listen to it to long before it goes into protect and shuts down.

I have 4 mtx thunder 8000 15s with the mtx 7801 amp and currently running 2 dual vented 15 inch boxes, what is the best box to use with them? Vented?sealed?ported thanks


It really depends on the music you listen to. 15's are meant to reproduce longer frequency waves, thus lower bass. The box dictates the kind of control and frequency you will be able to product. A ported box is used for mostly hip hop and rap. A sealed box is for more rock, pop, classical. The sealed will give you tighter response (basically the air acts as a cushion, not allowing the cone to reach full excursion easily), and a ported box give little resistance against the cone and allows full movement of the voice coil. Vented is just a ported box. But you can tune ports. I only recommend tuning ports if you are going to competition.

I need to know the deminsions to build a box for my rfl mtx 15


If it is an open air sub ( hole with mesh in the center of the magnet) no ports are required, and the box should be sealed on the inside with silicone sealant. If it is a closed air sub ( no hole in the magnet) you need a 50mm port about 120mm long Box size will be 16 inches x 16 inches x 16 inches

What size box do i need for a cerwin vega v124 and ported or sealed


Hi there, If can you give me an average dimension of your trunk your installing it in. And Ported - Sealed is really based on what you are trying to achieve in the vehicle. Ported in my opinion sounds better in cars with an enclosed trunk where as a sealed subwoofer plays better in a hatchback vehicle where the car itself acts as a second box.

Have kenwood mono amp 4,2,1 ohm capabilitie. What is the best sub to run. The amp is 1600 watts, howmany ohms and 1 or 2 voice coils.


Hello pelikant75,

The best answer depends on your budget for the sub(s) and exactly what kind of sound you are looking to get. Your amps RMS output at 4 ohms is 200 watts and at 2 ohms, it's 400 watts. I could not find that it was 1 ohm stable.

If you are looking for the absolute best bang for your buck, I would highly recommend a pair of entry level MTX 10" subs, model 4501-04, currently priced by Crutchfield at $49.99. And if you buy a pair, they throw in a free Bass Slammer BS210S sealed enclosure. The MTX's power range is 112.5 to 225 watts each, right in there with your amps output. 2 of them in parallel give you a 2 ohm load, just right for your amps best power. And they sound great. You simply can't find a better deal for $100 bucks!

If you want a little better SQ, a pair of Rockford-Fosgate P1S410's should be considered. Again, going to Crutchfield, they currently have this one "BOGO" (buy one get one) for $99.99. You will have to provide your own box, though, no free one with these.

Finally, if you want the best SQ, and your budget allows, consider a set of Alpine SWR-1022D's for $179.99 each. These have dual 2 ohm voice coils, allowing you to series the coils and parallel the subs, resulting in a 2 ohm load to you amp just like the MTX's and RF's recommended above. You will probably want a somewhat larger enclosure for the Alpines as well as a fatter wallet. Your amp is right at the lower end for powering them, so they probably will not be as loud. But they will sound good.

One thing we haven't discussed is the box. The enclosure is just as important, perhaps even more important than the sub(s). More accurate bass is generally produced from a sealed enclosure. A ported enclosure will be louder, but at the expense of sound quality. And whether it's sealed or ported, the enclosure needs to have enough internal volume for the particular sub you are planning to use. A sealed box in the range of .75 to 1 cu/ft will be OK for any of the recommended subs. Add about 15-20% more volume for a ported box and keep in mind that the port needs to be specifically sized for the frequency for which it is tuned.

Hope this helps.

According to MTX they need 1.25 cubic ft per sub sealed and 2 cubic feet vented. Most pre-fab boxes will work for those subs.

Mtx 1501d no sound


There are a number of things that can cause it to act as you described. Have you pulled the covers off of it yet to see if you can see any problems?

If you do, disconnect power from it and don't touch ANYTHING on the board when ANY of the 3 LEDs (2 are not visible from the outside) are lit.
