i need help with port length on a 4th order bandpass

i was wondering how you get as minimal port length as possible and 12 inch minimal port width
my car is 35 inches max width 50 max depth and 27 max height if any of that helps

i will be using 4-6 obsidian audio 12s at a 2:1 ratio. i want my box to peak at 35-40 hz
will be using 4000- 5000 watts
