I am a C3er posting this question for my dad who just bought a 86. The speakers emit a whining sound that varies with engine rpm...seems to only happen with the radio off. Im guessing this is the amp being not turned off with the radio??? Could someone lend some tech support on how to correct this. Thanks in advance.
I'll also bet it is the bose amp. If it is and he plans on keeping the car for more than five years it would sound better and be a better plan to put in different speakers/wiring and a CD player. Thats what I did...I decided I wasn't going to replace the amps for the second time in two years.
Sounds like the amplifier relay is stuck on. Try pulling the amplifier relay and see if the alternator whine stops. Amp relay is behind the instrument panel on the right side of the radio and has a pink, black, orange, and pink/blk stripe wire on the socket.
