Installed this weekend, I did add a couple pounds of "pillow stuffing" since the box was a tad smaller then what I needed. I have noticed some flex already but im not suprised with the subs that are in it. I will add triangle shaped gussets and some "trim screw" to try and hold things together.

A sheet of real MDF (not the cheap underlayment) is $32, carpet and glue around $15 so for what they want for this its a good deal that just needs some minor tweaks.

Ordered this as my first enclosure, put two 12" subs in it and I haven't found a box that hits as hard and as clean as this one has. Will definitely buy from SonicElectronix again for my car audio needs.

I ordered this for 2 crunch gpv's about six months ago because I didn't have the tools to properly build my own box. After six months this box is still holding up and works perfect with my subs.
