Default Ported Box in a ported box?

Hi, I have 4 Kicker CVRs laying around and I wanted to make a box for the back of my car. Can someone help me with the specs on the tuning?

I am looking to do it as two ported boxes inside of another larger ported box. Two subs on each side facing in, all sharing a top and bottom wall.

These are the dimensions I'm working with: 15" in height, 40" in width and 29" in depth.

Here is a sketch: image_1363800003629848.jpg

Do you have an idea of how much more space I would need? I'm going for the loudest I can with what I have as a temp set up. I have 4 kicker cvrs laying around, a bunch of plexi and mdf and 2 autotek mean machine 2500s. I don't mind taking out the back seat, I was just hoping it would fit in the trunk but i can improvise
