Well, I pretty much did not get the help I needed in my last thread, so I am starting a new one with the exact dimentions I have to work with, and if anyone can help me calculate the volume of this box, help me design a port, and tell me where the ports should go I would greatly appreciate it.

Here are the pictures/dimentions of all the space I have to work with in the back of my Extended cab Gmc Sierra under the bench.

FRONT

BACK

I will be putting 1 Stereo Integrity Mag D2 12" Subwoofer firing upward into the seat, and I did leave enough room for the excursion of the woofer.

The box for one subwoofer will need to be 1.5 Cubic inches tuned to 32 Hz.

Mag Specs:
