You need either 1) Longer port length or 2) Lesser port area. It would take me ages to find the PDF of Kicker's web site, but what I just told you are general rules for doing what you want to do. The second option would probably be best, for DD. If it says 30sq inches of port, like a 2" X 15" slot, just do a 1.75" x 15" slot to get where you want.

How is the port made? Slotted, or with a tube stuck in the box?
