This is a rough sketch of what I can fit in my SUV. The 2 drawings on top are internal dimensions and the last one on the bottom is the whole enclosure made with 3/4 MDF.

I'm aiming for a 0.75 cu. ft. enclosure. I'm not sure if I calculated it correctly.

Is it accurate?

no.

to find the area of a trapiziod prysim its 1/2(bhd) so it would be 0.1041 instead of .130. i would personaly make the box a rectangle for strength reasons and then add the sides on as hollow pieces

I got .63 internal

Those are some really shallow subs if they need less than 5" depth

well its 1/2(12 x 5 x 3) divided by 1728 = 0.052 for each chamber

Thanks. I just looked at my original draft on paper and the depth of prism should be 3.75 instead of 3.

It should come out to 1.302 and 0.7552 total right?

Yes, a rectangle would be stronger but there is just no way a 0.75 rectangle enclosure would fit in the wheel well of the car. Hence, the v-shape design.
