idea for sub enclosure

[Lschevy 3]

I been going back and fourth for the past few weeks about doing a enclosure to go under the rear seat in my truck. I entered my measurements in the enclosure calculator on the12volt. and i came up with 4.7 cubic ft but it have the transmission hump thats right in the center of the floor and i dont know how to subtract that from the total that i got from the enclosure calculator....do you guys think and enclosure like this would work with a external port? Im still looking around for some good 10's that would work with 1 cubic ft or less

measure the h x w x l of the transmission hump as if it's a rectangular box and subtract that from 4.7 cu ft. unless you're planning to fiberglass it. than i would assume about halve that space is lost.
