I'm having a problem with my factory non bose radio. I started my car last night and heard a pop sound. I turned up the volume on my radio and no sound was coming out of the speakers. I'm still able to switch through the channels. When I load a CD it starts counting. I don't think it's a fuse issue cause I wouldn't be able to switch through the channels or load a cd. Anyone have any suggestions before I buy a aftermarket HU and the metra kit.
