Best sub for the money! I've done installs for years, and have had many subs in my lifetime. I'm not usually one to write a review, but these subs are legitly worth talking about. i couldnt be happier with the amount of sound i get out of one. most people think i have two or even three and are suprised at the one in the trunk. i would recommend this to anyone and everyone. note: i am pushing 1000watts rms to it at one ohm.
