amp rebuild?

[2001f150 10+ year member]

I have a Kenwood KAC-8402 and recently it has been giving me issues such as engine whine. So my question is there any way to take aprt the amp and fix this? I have heard something about a RCA ground board? Just wondering if there is any way to save it. I know its old but I dont really have the money to go out and buy a new 4 ch, and I'm really tireds of not having any music.

Well if engine whine is your only problem, you can look at other things, such as the power cable being to close to the rcas, or just bad rcas together..

you can also try a ground loop isolater,

you can rebuild an amp, pretty much all the parts can be found at radioshack, and there all numbered on the circuit board,

you would just have to know whats broken
