Nice box

Nice small box I had a kicker L7 paired with this box and gives off nice tight bass, sounds good I also had 2 12" kicker cvr's in a ported kicker box and sounded as good if not better depends if u like that loud ported sound or tight sealed bass.

The box that never gives up!!!!

I am using a MTX Thunder Square and even though it is just a little big for the sub it sounds great!! I have only one of these monsters in my car and it hits verty hard and crystal clear. If I was asked, I would say it is a must and buy one.....or more.
