Im Impressed!!!

I just bought 1 these and put it in the back of my Montero and it hits very hard. I have it in a 3 cubic foot ported box and slams harder then the 2 12's i had in my SUV before. I looked everywhere to find info on these and I took a chance on them, and I'm very pleased. Easily the best woofer for the price.
