Ported box for 2 15" PG Ti15D

[Anonymous User 10+ year member]

I was wondering what is a good size & tuning for two 15" Phoenix gold Ti15D. Right now there in a sealed box, but i want more output from them. The amp they will be run by is a Rockford Fosgate 800.2. My max measurements I have for the box for the space I have in the rear of my minivan behind the 3rd row seat is 27" High x 17" Deep x 42" wide. I used the RE calculator & i got this.

but since I got a hatch/minivan, wouldnt i get more output from subs up/port back? I also want this box to be able to fit in my Saab 9000 also which is a hatch too.

what is the best way to fire subs & port in a minivan? what would be the best size aeroport to use also for 2 15"s? I was thinking either 4 4".
