Here's what I have come up with. The box would go behind the rear seat on the passenger side. The piece of plywood on the other side is where I have other stuff mounted, amp, inverter, terminal strips for lights, etc.
The box works out to 0.685 cubic foot, that's with the backing ring inside it to recess the sub from the face. I have 4-5/8" depth at the center of the hole, and 3-1/4" at the top. The sub I am planning on running needs 3-3/8" depth, and requires 0.60 cubic foot. So, should I go the the trouble of making the sub recessed, or just make the whole box 3/4 of an inch shallower, forgoing all the extra trouble to gain some sub clearance on the front? Then my volume would be 0.594 cubic foot. This box is drawn up with 3/4 MDF for the front and back, while the top, bottom, and sides are out of 2 by dimensional lumber, so they are 1-1/2" thick. Lots of strength and some beef to run the screws into, probably overkill, is it excessive? The box would have more volume if I didn't do that, but it doesn't really need more space either according to the sub's specs.
This is the sub I was planning on running, anybody have experience with it? Kenwood eXcelon KFC-XW1000F.

How about this amp (much cheaper on ebay)? Is it too dirty? I like the idea of running a single amp for my door speakers and sub, and I'm not looking to go all out with my system, just want clean clear easy to listen to music. Kicker ZX700.5.
