I recently bought a used '07 Cooper S from a Mini dealership in Richmond Va. Everything has been going great with my Mini except the other day I was driving home and my radio quit working, the guy who had it before me had put in an aftermarket system in. I checked the amp and the error light was on so I was going to just switch it out, but when I hooked up the new amp I get nothing from any of the speakers. I didnt have to do any wiring I just had to swap amps. Anyone have any ideas before I drive 2+ hours to the dealership?
