Default Ideas for a sub forward port foward trunk box. 2 12"s

So after spending 2 hours in Google sketch up i gave up (anyone know how to change the settings for a different unit of measurement, I clicked the wrong one). I have 2 15" BTL's and i wanna do a sealed Sub forward port forward trunk build @40hz. I was wondering if anyone had any suggestions on the location of the port. The double will be double layered 3/4"MDF only the top plate of the box will be single sheet. i have mdf already attached to the upper part of my trunk.The subs will see around 8kw.

These are the Maximum dimensions:


Port idea for the middle of the box:


I Also have 8" aero port/sewer pipe


Any ideas? or is this just not going to work?

I don't think 4" will have enough port area.

My box is 36w 16h. For two 12" and an 8" aero

I don't think you will be able to find enought room for the amount of port you need
