Sealed box dimensions for mtx 9500 12's?

Question

i want low and hard hitting bass while maintaining sq and i have a little car with enough space for these just not a 6 cub or whatever sized box.

i'm gonna build it 30" wide and 15" tall but not sure how many inches deep it should be!! mtx said 1.5 of airspace per sub but thats only like 12 inches deep and my l7's need 2 feet of airspace and were'nt near as deep or as heavy!! i would think the smaller the box the less bass it would reproduce??? any suggestions? and not to mention the subs themselves are like 9 inches deep into the box so i assume the box needs more airspace for these!
