I don't believe they have that option available, probably because everyone would just repair their speakers and not buy more. Depending on how bad the tear is or how much foam is missing, you can buy sealer for it that works fine if you don't mind what it looks like. I have used a thin layer of clear silicone caulk to seal them up before and also used it to seal a hole in the actual speaker itself. You want to use something durable and pretty flexible when doing it, but the possibilities are endless. Hope this helps and good luck!

before you do that i would recommend seeing if you can send it in under warranty because i know that a lot of speakers when you dissemble them you end up doing more damage then good.

You want an amplifier that is rated for the subwoofers. In your case your subwoofers are rated at 1500 watts rms each, so you will need an amplifier of 1500 watts rms or more for one subwoofer. good luck

The size of the wire has more to do with the amp's output than it does with the speakers. The wire should be the same size throughout, from speaker to box, box to amp. A minimum of 16 guage multi-strand wire. Most amps that put out up to 500 watts max or have an RMS rating in the 300 watt range should do fine with this. If you want to be on the safe side, there is no limit to how big your speaker wire can be, only how small or a minimum. If you're using a very high output amp, like over 500 watts RMS, you can use 12 ga. wire. If you want to be on target for your size, I need to know what amp you have and how many speakers you have.

Check the fuses on the inline and the amp(s). Then check the power and ground for solid connections and the remote if needed. By process of elimination you should be able to find the fault in the wiring. If all checks on the above the problem would have to lye in the RCA's or speaker wiring. Also be sure to have the proper resistance in your subs (ie.2ohm,4ohm) and that the amp can handle that resistance.

Hello familia_gome,

Those MOFO-15's have dual 1ω voice coils. So the only way you can get 2 of them to present a 2ω load is to use 1 voice coil on each one with the two of them wired in series. Using both voice coils, you can get a 1/4ω load by wiring the voice coils in parallel and then wiring the subs themselves in parallel. You'll get a 1ω load with the voice coils in series and then parallel the subs. Or you'll get a 4ω load with both the voice coils and the subs in series.

Here's a link to Power Acoustik's PDF for the MOFO's. I recommend that you check out the wiring diagrams on page 3.


Hope this helps.

It depends on how many channels are on the Amp. If it's a 2 channel you can bridge it using the positive on one channel and use the negative on the other channel. The Amp will give the sub more power bridging the sub.
