on my 1992 SSE SC i get a interference some from the rear speakers when i accelerate slowly in reverse or drive.. it only happens until about 10mpg then goes away and does happen agian for the whole ride. it does this even with the radio off..... anyone have any clue?

is your head unit stock, or aftermarket? ARe the speakers stock or aftermarket? Are there any amplifiers installed?

everything is factory, with the facotry GAIN amp

it sounds like the speaker wires could be grounding out on the chassis, and picking up alternator whine.

it doesnt do it unless its in drive, even if you rev the engine in park/neutral... it seems ot be happening almost everytime i start the car and drive off.... its getting annoying..
