PIONEER Amplifier 1000w Max 4/3/2 channel GM-A6704
This Amp was running great until my RCA cable got bumped on channel b.I think it arched out. Ever since it has had pulsing on channel b. I am selling because I do not know how to fix it. If you have knowledge how to fix this the you could sell it for good money. I have owned it for 16months it started playing up 3 months ago.
