I would like to put a sub under the rear seat of my SCREW. it is a 2010 F150 xlt. If it has the harness for the factory subwoofer. Does any one have experience wiring it in from there rather than all the way from behind the radio. It seems like you would have signal, power, ground all at your hands.

thanks

 

My factory amp is under the rear passenger seat, maybe look and see if it is pre- wired just for the heck of it. It probably depends on the radio you have if there is any pre-wiring at all.
