SPL in F-150 Reg Cab (04-08)

[MKader17 332]

My buddy had talked to me about building a box for his F-150 for 2 12" Xplods. Looking around I think it may be possibly to get 5 Cuft. (or very close) for the 2 12s. behind the seat I was curious what is the best way to face the ports and sub. I think the only way to face the the ports is up, but I do have the option of either down facing them down or foward.

What is generally best practices for SPL?

He will not be getting new subs so no reason to ask

I would guess sub up & port up.

Subs forward port up, subs forward port side.
