Need Help box design 2 Sundown sa-12 dual 4ohm going in my 2001 grand am

[ERICROCKFORD]

I got 2 sa-12 dual 4ohm going in my 2001 grand am . I going to push them with my RockFord Fosgate T1500.1bdcp . I really would like to fire the sub forword and port it up throw the rear deck with one large port I have some room to work with 32w x 16.5H x 15D I would like to tune it about 32-37 hz. Any ideas.

What Kind Of Port Were You Trying To Make A Slot Or A Circle?

Also What kind Of Clearence Do You Have On the Opening Of the Trunk?

Its a bad feeling when you make a good box and it does not fit

i have a design for 1.8 tuned to 32 hz for a single e12 but you can make a dual box out of it and face the subs in the cab. i did the same thing with 10s in my 2001 oldsmobile alero. pretty much the same car. i just dont want to waist my time posting it if you dont want it. should work fine for a sa 12 but i think they need 2 cubes.
