Do I have the right port area for my system?

Hey everyone,

So I've designed my box for my 2 15" Kicker L7's (06S15L72) and I've got a question for you experts on sub woofer mechanics and box design. To start off here's my basic specs for my system as well as my design specs:

Box design:

-11.79 net cubic feet

-150 sq. in. of port area

-32.5 hz tuning

-the big hole in the back will be a plexi-glass window

Electrical set up:

-kicker zx2500.1

-270 amp DC power H.O. Alt

-stock Toyota True 2 batt

-Big three 0 gauge

-Rockford 0 gauge all around

I'll be running the subs off a kicker zx2500.1 in the back of my 98 4runner. I decided to go with subs up port back after reading up on the benefits of doing so in mid size suv's.

My question: I know the port area is within the recommended port area range for this size of box, but I hear that using a smaller port than usual is advised when overpowering subs to keep a balance of pressure. Is the port area an acceptable size to create enough back pressure for the 2500 watts RMS amp I will be putting to my 2 1000 watt RMS a piece L7's?

Here's an image of my design below:

Any comments/suggestions on my box design are also welcomed.

*oh and ignore the tiny measurements like the 1/64ths and stuff, just cldnt get those spot on in the sketch up.

looks fine, probably want to double up the baffle if you can.

Ah yeah, i got plenty of room so i'll likely slap another sheet of 3/4 inch mdf on top and countersink em

Any other advice before i start building this bad boy?
