okay so my little box design didnt make it but you guys know how truck boxes look. need to know how to do bracings in it also.

you can go with a top firing port. if you did 60sq" (8.5 x 7) it would need to be 10.75" long to be tuned to 40hz.

as for bracing, wooded dowels are my personal favorite. all you would need to de is between the front and back. the port walls may add support as well.
