I recently had my D1 repaired. The screen was toast. Company did a great repair job. I reconnected it and everything was great. I wanted to run more power to my door speakers. So I cut the white, white/black and gray, gray/black speaker wires. I attached the wires running to the door speakers to the amps output speaker wires. No sound came through. Amp fired up and all the RCA outs work fine. I reconnected the speaker wires to the original spot and now I have no sound at all. No radio, cd, video, nav or beebs. Why would the sound not return after reconnecting the wires to the way they originaly worked. The read door speakers stopped working as well once I made the cuts. I did not cut the wires with the unit on. Is there a Mute I do not know about??
