What kind of truck do you have? Year? Standard cab, or extended? I have plans for a box in my gallery for a dual sub setup. You could easily adjust it and add more volume to the boxes. You can usually make the boxes slightly smaller if you seal them off. 12" subs only need 1 cubic foot of volume in a sealed box.

See the thing I want todo is creat a ported box I have all the necissary tools and equipment for this I just need to know how to measure the cubic feet in the box now from what I understand is you multiply HxWxL and divide it by 1728and that will give you your awnser is this correct?

right, but What you do is pretend the triangle part is squared off, then measure it as such. Then, measure the part of it that's slanted, preted like it's still squared off, and divide by 2. Did that make any sense? It's hard to explain w/out visuals.

So wait this is what I figured with your last post Ryan you LxWxH divide by 1728 then divide by 2? if that is correct I have this formula 16x16x16=4096 Divde 4096 by 1728 gives me2.37037037 then divde that by 2 and I will get 1.18518519 Is this correct? If so screw it I'll just make a sealed box. I was going to make a ported box but my calculations were off by a hair I had 16x16x17 divided but 1728 and that gave me 2.51857852. the problem with that is how I would fit the 17 into the 16's. Does this make sense probally not If your having trouble understanding this I'll explain it better if you ask~kyle

Yeah. Bigger or smaller doesn't matter. As long as the interior airspace is the same, it's going to, for normal purposes, sound the same. Especially with a sealed box. Here, see if this helps.

if your other two sides were 16 & 16, the math would be 16x16x8/1728=1.185
It's also a good idea to make the dimensions uneven, like add a third to each side starting with the depth of say 8 or 9 inches, width of 13 - 14, height of 16 - 17, something like that. having all sides equal can make the box resonate and sound bad. I generally start with the face plate (front), top, bottom, and back, then drop the two sides in.
