Me and buddy are installing subs in his car. Its a 07 Tahoe with Bose sound system and Nav. He bought the wrong pac unit but on further inspection, it should work. The HU has 4 inputs and the pac unit only has 2 inputs. I would assume that i can use two of the factory ones but i dont know which ones. If the Pac unit doesn't work, we got a LOC. Ive never used one of these. Apparently you can tap into the sub in the center console but i have no idea what to attach the power and ground and other wire to. Any help would be appreciated.
