I have an 06 Navi with the Navigations, and THX. I've installed a 15 MB quarts sub to give the THX a little more thump, and need help finding the factory amp location for the stock 6". I need to find the stock amp location to tap into the remote wires to turn on my new MB quarts RAA1000. I've already ran all the 2awg wires, line drop, and RCA except the remote wires. Or can I just find another ACC wire and tap into it?
