Whenever my friend puts a CD into his HU, his subwoofer amp just powers off. The amp works fine with the radio, everything's bumpin. As soon as he puts a CD into his headunit, it's a Pioneer I think, not sure the model, the amp shuts down and there is no power to the subs.
I am not sure the problem here, anyone else ever have this problem? I havent checked the wiring in his truck yet, because he just told me about this problem. Can anyone shed some light on this situation?
