My '07 Vue V6 AWD came with the standard AMFM/CD/satellite stereo, NO sub. The optional stereo upgrade which I did not get came with a sub-woofer located in the hatchback, on the passenger side just to the rear of the wheel intrusion. If I were to remove the trim panel on my Vue (which is not an not an easy job, hence my question), would I find factory wiring for the optional sub-woofer? This would obviously simplify the installation of a sub-woofer versus wiring one in from scratch. Thanks.

 

I would look behind the radio in the front to see if there are any wires for the sub coming off the harness, since if it ain't on one end of the harness, it sure ain't on the other.
