Problem is we are hearing a popping sound in the subs that are hooked to the amp. I have power to the amp, a good ground. Just say this when the sub wires are hooked to the amp it starts the popping noise, and all that will sound are the subs, we do not get any sound from the side door speakers. Unwire the subs from the amp all the speakers will play including the subs but of course not thru the amp...hope this makes sense. Thanks for any help
