Hello All,

I want to install a Kicker Hideway Subwoofer under the rear seat of my 2012 Silverado Extended Cab.

To do this, I need to connect it's harness to two speaker's wires (a left and a right), and I'm assuming the rear speaker wiring would be the easiest to get to since I'm installing this under the rear seat.

Any idea where I can find this wiring in the rear of the cab? Does it run up a panel somewhere that's easy to get to?
