Default Help!! Poor Sound coming from my Kicker ZX650.4

So im getting poor sound quality out my 4 channel amp. Sounds like im sitting in a tin can now. it never used to be like that, it just started happening out of blue. I hooked another cheap amp up just to confirm that it wasn't a cable or grounding issue. Everything sounded great with the other amp.

Everything else on the Kicker amp seems to be working and functioning just fine. Any help would be much appreciated, Thank you

It doesnt seem like FET's to me either. I certainly don't mind replacing FET's or anything on the PCB's. The amp shouldn't be going out like this, i know its about 8 years old but it doesn't even have 50 hours of play time on it and its been garage kept since i bought it new.

Am considering buying a (for parts only) amp on Ebay and swapping some parts but id really like to know if anyone on here could assist me before taking a gamble on a (not working) amp.

Yeah my bad, i forgot to mention that. i took the cover off and couldn't Visually see anything burnt or anything wrong at all with the board. All the FETs seemed just fine, there aren't any signs of them even getting hot there in the middle or anything.

Visual inspection of electronic components really doesn't mean a whole lot.
