Single Fi Team V2 15 Box Design

[Sv05lex]

Hey what's up guys, I am trying to get some input on a box design I'm working on in Torres/Sketchup. 

I had designed a box with Led lit plexi that fit over the wheel well in my 4runner, but I want to try something a bit different this time. 

 

Can someone with experience lmk if anything about my design numbers should be tweaked? 

The 1st rendering I was thinking about invert mounting the team on the side, but I think i'd give up more air space than it's worth by making the box narrower.

The 2nd is what i'm leaning more towards is a rear firing with side port. 

 

I have big 3 done with 250 brand x. Saving up for a few banks of yinlong and a surge 7k, so in the mean time i'm trying to get the box done. 

I'll have to get a better estimate of bracing displacement, 45's/Dowels.

The inner end of the port should be as far as possible from the sub,  the first design looks like really asking for trouble.
