I have had a few PM's on more information on the storage box. I took the best pictures I could with the hard top on. Here is the specs.
1 1/2 sheets treated plywood 3/4"
2 full extention 24" 150lb drawer slides
box of screws
box of self tapping screws
2 rolls of walmart trunk carpet
1 recessed tie down for drawer handle
4 small tie downs for top
24' of 1" aluminum angle
Total price a little over $100
The drawer is 34"wide x 25 1/2" deep x 8 1/2" high
the face of the drawer is 10 1/2"high
the slides are about half way up the drawer
the top piece is 38 1/2" wide x 27 1/2"
the front angled piece for the speakers and sub is 16 1/2" x 37"
the 2 sides are 11 1/2" high x 38 1/2" at the bottom and 27 1/2" at the top.
There is a divider between the speaker compartment and the drawer, don't remember the size, and can't get to it to measure. The speaker and sub compartment is also sealed for better sound. I can turn it way up and have NO rattles.
I didn't put any wood under the drawer, I just plugged the seat holes and put some carpet down for sound deading.
To secure the box the the jeep I used self tapping screws inside the compartment into the wheel wells 5 per side. And then some down from the top through the aluminum angle on the sides.
