Fi Q 15" fully loaded box help

[Jordan Guess]

I have a fully loaded Fi Q 15" running off a AQ 2200 going inside of a Ford Ranger Xcab. Max dimensions are 28W x 30H x 18D. Planned on doing sub up port up unless there is a better setup for rangers. Not sure how much port area I should go with but what i came up with is:

Max Dimensions: 28W x 30H x 18D

Port Height-16.5 (technically the depth)

Port Width-4.5

Length-50

Woofer Displacement-.16

# of extra baffles- 1

# of Common Port Walls-3

This puts my port area @ 74.25 sq in. (17.35 sq in per ft.)

Net Volume of 4.28 cu ft.

Tuned to 28.05HZ

Anyone have any suggestions for me before i start off with this build? Not sure if I have to much box volume or to much port area but all help is greatly appreciated.

Thanks.

Here is what Fi's recommends. What are your goals for this sub?

Ported box: 2.8-4 cuft @ 28-33Hz

For that sub and amp I personally would do 3.5 cuft tuned at 32hz with 14-15sqin of port.
