15" DC lvl 4 w/ lvl5 soft part

does anyone have an enclosure design for one of these subs? i have a dodge caravan without the 3rd row seat so i can fit a big box. the box it came in is tiny with 4 2" ports all you hear on lows is port noise. i like to bang daily no competing but like to get it to hit hard and loud. i want to build a box till i find a match to this or find a matching motor to send to get both built. If you have a motor to match pm me thanks for any help.
