LOL if it was ran to a CONSTANT 12v - It would NEVER shut off - That is my whole point! - You obviously have it ran to your IGN / Switched 12v. lead, although I can't imagine WHY your HU wouldn't have a dedicated remote turn on lead right off of it's harness...Maybe i'm confused, its ran to the back of headunit to the wire that is my power for my deck, I was under the assumption that's the 12v constant? Anyways, my amp doesn't always stay on, turns off when my car shuts off.
