Yes it shuts off.. I even checked to see if the light on the amp shuts off... I just bought a new battery and it's working fine for now, we'll have to see what happens.. I even went as far as buying a volt meter gauge to put on an A-pillar just haven't installed it yet, that will be my next mission, and that way I'll be able to monitor the voltage and keep a closer eye on it. I also checked behind the kenwood head unit and check the wiring, and it appears to be fine.. I hooked up the remote wire from the amp to the back of the head unit, along with some pink wire from the stock harness to the remote wire behind the head unit because the Bose speakers wont work if it's not connected to it, then I also hooked up the blue wire that said Constant P to those two as well and my amp works that way, and yes it shuts off as well after turning the key to the off position and opening the door, so I dont know what it could of been that killed my battery.. Also my amp is an 800 watt kenwood amp, with two 12inch Kicker comp subs... Any other suggestions? Thanks again.
