Ill stop by sometime early next week (I'm sure you guys are busy this week)

and have you or your builder look at the design and measurements

I have a request though I need the box to be internally braced (with either 2 x 4s or something) and then Fiberglassed on the inside to add even more strength to the box

I plan on dropping 2 12'' Fi BTLs in the box so it has to be VERY strong.
