if you have the kicker 1200 i would save up some money for a better sub to use all power you have. you might be able to find 2 12 cvr's on ebay for about $140. a kid i know just got 2 and a sealed box for $160
Ahh, come on now. I'm sure the cheaper audioburn stuff sounds like "crap", but I have one 12" AW1208T and that thing actually sounds half descent. Its in a 2.5 cubic foot box, and that thing gets extremely loud, and like I said, it doesn't sound all that bad, not wonderful, but not horrible.
Soundstram makes a great sub for that price, now ive only heard there lowere end sh(t but it got effin loud! not the best sq, but your looking for spl anyways... SoundStream T4-12 should do the job
