i want to build a box for 2 SA-8 V2s. i have an 01 gmc sierra reg cab. i want to put them behind the seats, the space i have is 54"L x 14"H x 10" bottom depth x 5" top depth. they will be powered by an SAZ 1500D. I want to tune the box to 33hz. the idea i had id for one sun behind each seat and have a port coming out thru the middle, or two ports each firing towards the doors from behind the subs.
Can i get some help figuring this out?

You should do both subs on one side facing forward with a port coming out the other side of the box. Depending on how much room you want for these, you don't really need to do an angled box. You could have around 1.5 cubes with 12.5" height, 7.5" depth, and 55" width. I know this, because I just built a 1.5 cube box @ 33 hz for my regular cab truck lol

Yeah, here is a picture of the box: ImageShack® - Online Photo and Video Hosting (http://imageshack.us/photo/my-images/716/dscn0142y.jpg/)
Basically, it is 12.7" x 55" x 7.5" with a 31 inch port that is 6" x 3.5". You want to make sure that you get both of your subs to the left as much as possible to be away from the port.
Here are the pieces of MDF you need to cut.
2 - 12.7" x 55"
2 - 6" x 55"
1 - 11.2" x 6"
1 - 6.95" x 6"
1 - 6" x 31"
