18"bl enclosure designs

[06cbrboy 0]

Im am trying to get my box for a 18" Bl made before i order so that when it comes in i can just drop it in and go. Here are the specs and a couple of scketches. I also have a coulple of questions since i dont have the sub in yet. My main concern is i am wondering if the subwoofer is going to fit between the edge of the box and the L port. The distance between the two is 19.5 " is this enough room to fit the sub and the outside of the basket where the screws are. Also what do u think about the dimensions and the design. Lookin gor constructive critisism and ideas. I designed it with the re box builder. Its going in an 04 Jeep Cherokee Limited.

does this design have too much port area

Thats 8 more square inches than what they recommend (12-16 sq inches per cubic foot)... i dont know what that would do, anyone know?
