My max height is 15.5". I know it going to be a pain. Depth is max of 44" and max width is 34. Are you using a box design program. If you are could you take the time and tell me how to use it sometime cause. I would like to learn. Just get a rough idea what it will be. Because i am going to finish my trunk this weekend.

Ok, so...here's what i got

width: 30.5"

Depth:30.5"

height: 14"

those are all internal dimensions.

Port: 12"x4" length of 10"

this will tune it to 33.8hz to be exact...and after all displacement (port displacement and driver displacement) will be 7 cubes @33.8hz. Should work great, peace

Okay got max dimensions. 15in tall, 30.75in wide and up to 36 deep. If you could sketch a desigh for a slotted port box with those specs that would be awesome. i know there is angling to be done. Will the subs be as loud since they are probably not going to be directly facing the back.
