building box for 07 mustang

Heres how I want it, can you help me with the box interior volume. I need it to be between 1.6 and 6 cu FT.

Can someone please come up with a box design for a new style Mustang. It's for 2 kicker cvr 10's.

Well it just needs the angle on the bottom. It goes up 9 Inches at a 22 degree angle. Then flattens out for 7 inches and thats all the room since it now hits the rear seats. The height of the box by the rear seats can't be taller than like 10 Inches. The front can be like12 or 15 inches tall. I want the width to be 34 inches wide. Then the top needs to be however long so it lines up with the bottom angle thing.

ok lets start fresh here since no1 can decifer your drawing and im pretty sure the measurements are not exact. no offense, but we are trying to help you out.  i have an idea to get more air space. you need to make 3 cardboard cut outs for the 2 side and the divider. make them to fit snug for the sides and divider.  then when you get the shape you are looking for, trace em out on mdf and cut em out. place them in the trunk where you want them to be.  then tape them down so they stand upright as if they were in the box themselves.  then foil off the work area, and tape around them to fiberglass the tricky spots of this box project. fg the sides and divider to the foiled off floor and wow, now ur making this box that isnt working out so well to begin with(sorry if i seem blunt but had a rough day, not ur fault) now you have then bottom sides and divider in place carefully pull this out of the trunk and build the front and top of the box and make sure the fg is strong enuf.  now you can finish it to ur liking, but at least you will have the max. air space you will need. let me know if that is what you were looking for.Make it Euro'n!!!
