I have a stock bose sound system. When I play the radio AM or FM, all of the speakers sound distorted. Even at a low vloume. But when I play a CD or tape, everything sound normal. Any suggestions.

 

I think this has something to do with your back windsheild. Seriously. I had a friend get his replaced cause he had problems running the radio and rear defroster. Take the car to the dealer and warrenty should cover.
