[QUOTE="ttocs, post: 1548876, member: 11896"] that is not going to help you. If anything you need to raise the voltage maybe with a relay but there should be basically the same relay inside of each amp already. The deck should put out the same voltage as the battery so while we say 12v we mean anything between 11.5-13.5v ish. The only thing I can think of is that the 11.7v is low and right on the threshold voltage needed to turn the amp on so sometimes it kicks it on and sometimes it doesn't. Next time you can't get it to turn on, disconnect the remote turn on wire that goes to the deck and then take a small piece of wire and at the connection to the amp connect the remote to the 12v constant and see if it will turn on then.
