whats a good 12" subwoofer that would rattle the crap out of everything and suck the air out of my chest? i dont have a set price im looking at, but the cheaper the better
power craptastic? don't get that. Really don't know what to tell you to get since you don't have a price limit set but a 12" RE XXX would prolly give you more than enough gut wrenching bass.
if you want cheap and loud you can get those Mofos or the kicker L7s..both will sound bad but their loud and cheap now if you want real loud but with some sound quality then you can go with the RE XXX, maybe even the SX, Eclipse Titanium and even the MTX 9500
you're gonna have to spend a lot of money if you're trying to get extremely loud bass from just 1 12. You're enclosure would have to be built extremely well and you would have to get a very large amplifier and probably a new alt if you're running 1000's of watts.
