The box seems to be of good build quality, but beware of your subs height that sticks up on the outside of the box. As you can see by the pictures you will need a sub that the outside of the box sub profile is very low and your rubber surround is very low as well. For reference my sub is a Alpine s-w12d2 and the lip that sticks up on the outside of the box is just a smidge short of 7/8 of an inch. From limited looking at least I only see the lower profile in older or cheap subs, it seems all the newer stuff has a higher lip and in most cases a higher rubber surround on the outside of the sub box. Even if you find a sub with a low profile lip and rubber surround, I think it will be either very tight or when bass hits your subs cone very well may hit the bottom of the seat. I want to run alpine and dont find anything with a lower profile in their product line , so the only workaround I found is a seat lift kit made by LMI Welding, which raises the lower part of your rear seats 2 1/2 inches. This kit does go to the tune of $160 before shipping and taxes. Again the box seems that it is built nicely, but buyer beware you may have to buy a new sub or order this seat lift kit. By the way it seems this company is the only one that makes the seat lift kits (as far as I can find). Oh ya, the second picture is to just show how hard the seat pushes into the sub. The impression from the sub you see in the bottom of the seat is from having the seat down only long enough to take the first picture. Overall I would recommend this box, just because the choices for under seat boxes for at least my model of truck seem to be pretty limited and I would be surprised if you did not run into the same situation with other boxes as well.
