Right now I have my 4 speakers amped, as well as one 10" subwoofer connected to a seperate amp. I have a distributer block to run the seperate power to each amp, and both are grounded. Everything was working fine for about a month, then my subwoofer would cut in and out. Then it got progressively worse, and now has stopped working completely. I have tried replacing the amp, which didn't solve the problem, and I have also replaced the sub and box with a friends to test it, which still didn't solve my problem. My fuses are all in tact, and my RCA's are hooked up tight. Any help to solve this problem is great appreciated!!!! I can't figure out why the system isn't working. Thanks,

Jared

 

Run a new set of RCAs to the sub amp just to see if it got pinched somewhere. Just run them over the seats for now to test. Sounds like this would be the most likely cause.

does the amp stay on when the subs stop playing?????
when you run the test pair of RCA also run another remote wire

 

Could also be the head unit output cutting in and out. Try a portable music player to see if it stops.

 

If you check and replace amps then it is must be problem in some wires, may be some wires could be short circuit check it current.
