Does it have the Amp and Sub? Is your Amp turning on? I ended up reworking my hook-up because they broke one of the audio wires to the amp and used the video cable instead. Mine also had a 6 ch in to 2 ch out converter hiding behind the radio that seemed to do absolutely nothing. Could be a wire has come off back there or something. These are definitely not hooked up by experienced audio people, I know a little and realized it could be simpler and better.
