Here are some more measurements.
The box is 40" wide. The front face will be perpendicular to the floor and is 11 1/2" high. It is MEANT to be a tight fit so tie-down bolts aren't needed.
Here is a little diagram of the cross section. The red lines are for interior dimensions. I just cut the MDF with my circular saw & trimmed with a jigsaw & sander. The 11 1/2" face is rather tight but my Kenwood 10" Subs fit just fine.
Though not all of the measurements are on this diagram, it's a start. Get the main measurements down on paper and you can fill in the blanks as you go along. I started with rectangles & right angle measurements so I didn't have to worry about exact angles so much. When I mated edges I just eyeballed it with my sander until the gaps disappeared.
