Nice box, but?

The following review is for NE122S, which is a part of the bundle you are viewing.

This box sounds awesome with my NVX subwoofers. I had to reflue the poly inside the box because not enough glue from production. Also, the terminals are cheap. Replacement is recommended. All that aside this box hits hard with the optimal manufacturers recommended air space. I replaced some CT Sounds 1250 rms Stratos off a 2000.1D CT amps. They couldn't even keep up, even with thier amps.alway bottomed out. I put the NVX3s in A NVX box with the specs. Night and DAY. These subwoofers just my be better than the JL W7. By the way the CT Sounds are in a custom box .

The following review is for SAV212D4, which is a part of the bundle you are viewing.

I wish I would had spent the money the first go around. These subs are amazing. I highly recommend these. The slam I only have my amp turned up half way bass settings on low and the are ridiculously loud.
