SA-10 Port area help

[N9neMillahhh]

Hey guys I'm designing a box for my new whip and am trying to figure out how to design the aeroport, but not sure how i should lay it out. Doing four SA-10s in a box of about 5.2 cubes, minus .4 for displacement, means 4.8 net before port. Although my rear seat does not fold down, but the middle seat folds down with a hole in the divider, so I think it'd be dope to have a big ol' port come out of that hole, but not extrude so far that i cant put the seat up if i need to. I don't have any experience with designing an aeroport box with knowledge of port area, so thats the main snag on getting it designed. Anyone have experience doing this kind of design? Am i just better off doing a slot port facing the rear along with the subs? I have two SAZ2500s powering the set of four. Want to tune to 31hz. If the aero through the seat wall isnt a good idea i might have to switch to four 8s or three 10s.

I know this is an old post but no one answered you yet. Usually 12-15 inches of port PER cubic foot net. I.E 4 cube box = 48-60 square inches of port. Port area also depends on power applied and how under or over sized your box is.
