[QUOTE="nhguy261, post: 8750339, member: 683296"] I'm a newbie here and in need of assistance. This is what's installed in my 1981 C3 Corvette. Kenwood KDC-X303 head unit Alpine MRV-F300 Amp Alpine R-S69 Speakers Alpine Sub-Woofer Model unknown Kill switch at battery I did not install this equipment, I had it done by a local audio shop. I took the car out of storage and it fired right up and the sound system worked but something wasn't right. I smelled mice and found the nest in the center console. I cleaned it up and found that they had chewed through what I believe is a speaker wire and the insulation on the antenna cable. I think the speaker wire contained five separate wires. Two on either side and one running down the middle. I carefully spliced everything back together, tested it and everything sounded great...I was happy. I called it a night and picked up where I left off but before I did, I tested it but the car wouldn't start, the battery was dead. I put the charger on the battery and the speakers began to howl. I disconnected the charger and started my research. I was told that the problem was how the amp was wired at the head unit. It had a constant power source. I disconnected the blue remote wire from the amp, put the charger back on the battery and there was no howling. I fully charged the battery. OK, so what does this mean? I couldn't understand how this could be possible since the system worked fine before I put it into storage. I decided to put an on/off toggle on the amp remote wire to kill the power so that it didn't drain the battery. I'll walk through what's happening now. [LIST=1] [*]Battery kill switch on [*]Amp toggle off [*]Start car [*]Amp toggle turned on and the radio works [*]Turn off radio and the amp turns off [*]Turn off engine [*]Turn off battery kill switch and the amp turns on...WHAT?? [*]Turn off amp toggle, amp remains off [*]Turn on battery kill switch [*]Start car [*]Turn on amp toggle [*]Turn on radio [*]Radio works [/LIST] I'm baffled. What's the point of having a kill switch if it turns on the amp when it's in the off position? Could a stray speaker wire in the splice be causing this? Is it a wiring issue at the head unit? Thanks for taking the time to read my lengthy post. All advice is welcome. [/QUOTE]
