I'm looking to put some subwoofers in my 2001 Chevy Tahoe. I''m a novice when it comes to car audio so I don't really know what I need besides the subs, amp, and speakerbox. I don't want anything that will be deafeningly loud, but loud enough. Would 2 12's be good for a truck this size or do I want more/less? I have no idea how big of an amp I would need. As far as brands I heard JL audio is the best hands down - Any truth to that? I'm looking to keep the price to a minimum, no frills, but I don't want junk either. What would you guys reccomend?
