I have a 99' Ford Explorer, four door, eddie bauer, and i'm looking into subwoofers. I want 2 12"s with a lot of power. I want it to be very loud, as it should be, but I also want it to be crisp and not just blasting one sound. I have been lookin at JL audios, Infinity Kappa perfects, and the new Sonys. I want to be able to easily hear the beat and I want it to be clean. Thanks for all your help and please send back some tips on what subs I should buy. Thanks guys.
