Where to run power cable for hidden amp

your amp install instuctions will show a "signal" wire. I think it is blue...... that is usually hooked up to an aftermarket deck. all it is, is a keyed hot wire that tells the amp when to turn on and off. so you can just hook that wire up to a keyed 12v hot i believe. I would look at your manufacture instructions before you start wiring anything. I would also mount your amp either in the trunk up behind the back seat or on the bottom side of the package tray steel. first place thieves look is under the seats.
