I hooked up two 10 inch subs and 1200 watt amp in my truck. I tested them to make sure they worked by connecting the remote wire directly to my battery temporarily. Everything worked fine. Then I tried to connect my remote wire to the back of my head unit, but this would not power my amp. So i spliced into the blue/white wire in the back and connected that to my remote wire, but still got no power to my amp. I spliced into the red wire in my wire harness running from my battery and connected that to my remote wire. This finally powered my amp, but when I turned my head unit on, it would play the CD, but no sound came out of any speakers. I un-hooked the subs from the head unit and tried it again and still no sound out of my cd player. I disconnected my battery and checked my fuses. Does anyone know why I am still not getting any sound?
