hows this box look for two 15" L7s and kx2500 in a suv...

I just got a SUV. I currently have my system walled off in a accord. So I'm afraid I'm going to get disappointed in my suv since I'm not walling it off. So I want to make sure I build a good box.



I'm thinking that after I put my subs in that box the tuning would be right around 35 hz. This box would also leave around 8 inches between the box and the back hatch. Then of course I will put the subs on top...so that it will be subs facing up and port towards the back.
