Hey guys. I have a 2002 Tahoe w/o bose and my subwoofer just stopped working recently. Sometimes it sounds like there is no bass, and other times like the speaker is just rattling and not making any real sounds. So I was wondering if just getting another factory sub for 70 is worth it, or should I just buy a Kicker CVT8 and amp? And if i do get an aftermarket sub how would i go about installing it?
