Hey guys. New member here. I was wondering if anyone could send some help my way. I have 2 JL 12W0's in a down-firing box under the rear seat, pushed by a JL 500/1 in a 2003 Silverado Ext. Cab with a Bose factory stereo. The problem that I am having is that my subs sound non-existent. I know that I need to upgrade to an aftermarket headunit, but I really don't have the extra $ to get one and the parts to make it work with the Bose system, OnStar, and steering wheel controls. Anybody have any suggestions on how I could maximize my sound with my current setup?
Thanks
