do this 12x 12 x12=1728

get your L x W x H and then diveide by 1728 that should give you your CUFT

use the calculator on bcae1.com. you can enter the amount of room you have, itll take away wood thickness (.75) then if you need it smaller you can adjust the way you want.

That might be one of the better prefab boxes. If you don't want to build your own box and have the money to spend, go for it.

still $150.. i might buy your box.. but im not sure yet.. i gotta measure the height in my car.. you said your box was 17" high but 99grandprixgt told me that he thinks 17" is too high.. ill measure later today and get back to you
