Calculating Volume? :|
I am getting ready to build my box for my single cab truck, but I need a little bit of help finding where I need to place my dividers to equal 1.25cu ft on each side.
Here is a drawing of the side profile with the measurments labeled.
And Here is the drawing of the front of the box.
This is where I would need the help. I am going to create three chambers total. 1 on each end for the subs, and the center is dead space for the amp to mount to. According to the measurements labeled, how wide would each subwoofer chamber need to be to net about 1.25 cu ft.?

Can't be done, the gross internal volume of that box is only, [assuming it's 3/4" MDF] 2.121 cuft., [57.5"x7.5"x 8.5" = 3665.625 cuin divide by 1728 = 2.121 cuft]

Is that universal for calculating volume? I'm not saying you are wrong, rather I am attempting to redesign the box and I need to know if this is universal so I can calculate myself.

In your case .Anthony you need 2x1.25 cuft or 2.5 cuft 2.5x1728=4320 cuin
