I have a 1991 Audi V8 Quattro - great car with an overly complicated Bose audio system, the one with the amplified speakers that always squeal. Does anyone know what the major components are and where they're located, beyond the obvious ?? Specifically, I know there's an antenna amplifier located somewhere, it recently stopped picking up FM radio stations unless you're sitting in the parking lot of the station but I have no idea where the antenna amplifier is located or what it looks like, any help would be appreciated.
