hi After installing my amp to the stock deck, my rear speakers have no sound. But after unplugging the RCA wires from the amps input, my rear speakers works again. If i leave my deck on and plug the RCA wires back on it works, once i turn off the deck and turn it back on, the rear speakers don't work again. Don't know whats going on. Please Help Thanks
I think it is impossible to guess what the problem might be, from you description. What is the "deck", and what is the "amp" - a 5.1 AV receiver of some sort?
