well i am going to tell him to go with dukks idea as I have an odd box at home that fits his discription to a tee.....just never understood why someone would build a box like that till now. It is a box for 2 10's facing down with about 3" of space between the floor and the subs.
So I am going to take the mesurments off of it and send those to him.
Thanks for the help guys
