[QUOTE="desertsoldiers, post: 7723089, member: 641339"] I've read posts about possibly fixes for this issue and all recommended solutions such as a speaker shorting out or a ground being bad is not the case. My setup is a Kenwood DDX418 touch screen deck and didn't start having problems with it until about a month after installation. The unit shuts itself down and restarts which I have not determined to not be volume level dependent as it restarts just as frequent at low to no volume as it does with mid to full volume (about every couple minutes or so). It's installed in a 2007 GMC Sierra 1500 (new body style) with OnStar and the standard Bose Acoustic package. In order for an after market deck to work with the Bose you must install a replacement stereo interface which I got (Scosche GM21SR - High-speed LAN stereo replacement interface). I ruled out the head unit overheating and I'm still puzzled about the possible solution. The first two images are the wiring diagrams provided by Scosche for the replacement interface. The third image is the wiring diagram provided by Kenwood for the head unit.

Kenwood says "When using the Optional power amplifier, connect to its power control terminal. Schosche says "+ 12V Remote Output (Amp remote, Radio On Signal)." I have my Amp for my subs attached to the RED - Accessory (+12V) wire which is the one where the power turns on with the key like normal.
