This Yukon came in with a decent system already with 2 L7 12" subwoofers and a Rockford bd1500.1. Simply add 2 more L7 12's and a Kicker ZX1500.1 in a HUGE ported box and you have lots of bass!! The box is covered in laminate that matches the factory dash trim. A Kicker logo completes the trim when the rear hatch is open.

 

On the driver's side the bd1500.1 is slightly coming out of an oval cutout in the trim panels nearly eclipsed by the new L7 12 nearby. What you don't see is the Optima Yellow Top battery that was installed in a custom welded tray behind the fender panel where the factory subwoofer was originally.

 

 

On the passenger side the ZX1500.1 is set up the same way as the Rockford. A bass control knob for each amp was ran to the front for adjustment.
