Sub box dimensions for oem location?

[Cstoliker]

Anyone have the measurements worked out for the maximum sub enclosure (made from say 1/2 inch mdf) that will fit in the oem spot on 2nd gen XLT? (2000)
Yea, I know it will be a lot more involved then building a square box.

Thanks.

There's a post here where someone build a wooden one, I'll try looking for it.
