Oh lots of replies. It just now notified me of them.
The box is 36.5 wide by 14 high, and 11 deep on top with 14.5 depth of the bottom. Total volume is 1.82cu/ft after port and woofer subtractions. The port will be on one side and the rear port wall will extend horizontally in the box 27.25 inches with a 2.25 inch slit. This puts it 29.5" from one wall and 5 inches from the other for a tuning frequency of 34.74hz.
I wanted to minimize the shake in the trunk because in this old car, the ECU electronics is in the trunk and I don't have much extra cash right now to dump into a full deadening for the trunk. Also this car has a massive moonroof that is removable. Its about 4ft by 3ft. I am thinking with that open with sub/port facing forward will form a sort of band-pass with the interior of the car improving sound quality.
I did all my measurements and was planning to cut tomorrow, so there is still time to reconfigure my box if sub/port forward isn't gonna sound great.
