well I did measurements in his truck and its near imposable to do a box behind the seats so im just going to do a center console box with a single 8. I do have a question tho. How to you calculate the displacement of a 5/8 all thread about 13 inches in length

It's so small that you can completely dismiss it from your calculations, it will be Length*3.1416 x (inner diameter/2)^2. Also I don't think you need bracing for a single 8" box.
