Rear Speaker Amp Fix? Or I'll Buy Yours! Bose Sigma 975 Rear
So I finally got around to taking out the rear seats and changing my back speakers. And I realized that one of the speakers wasn't even connected (I've never noticed this) I hooked up the new speakers and even when theres no volume I hear a high pitch noise. I know that its not the speakers because I tested 4 diff speakers and they all do the same thing. And I know that its the Amp because I tested both amps on both sides and switched them back and forth to be sure.
So I took the amp out, and noticed is says SIGMA 975 on it. Does anyone know what can be wrong? If there is a fix for this? OR if you have one or know of someone who has one and would like to sell it? Anything will help, thank you..
PS: I'll post a couple pics for reference.
