I am really looking for a little more base in my 08 Tahoe. I am not looking to put a huge box behind the thrid row. I've seen a few shallow subs, Pioneer, Kicker, JL Audio and Rockford Fosgate. Has anyone heard any of these subs. At one time I had a regular Rockford (12")sealed box and a Pioneer (10")tube, in my car and I loved the way the Rockford hit. But I have never heard any of the shallow subs. Please help. I want to put either a 10" or a 12" subin.
