Best box ever

The following review is for Dual 12in P, which is a part of the bundle you are viewing.

I put 2 American Bass XR in this box, wired to 2 ohms with my NVX 2700.1 amp. Man this box is amazing, sounds way, way better than the Q bomb box that I had. If your thinking about getting this box. Get it. You'll be very satisfied.
