Why 2 3" aeros? Why not at least a 4" aero or two or even a single 6" aero?

A six would be too long, 2 sixes obviously way too long, and 2 4"s too long. I want 2 ports, one on each side.

You can get an elbow and bend it or go slot port. Why do you have to have two ports?

im doin sub forward, ports up, one on each side. just one port would be ignorant. For the length needed for 2 4"s, i would have to do 2 different bends and make a loop.

3.25ft^3 before sub/port/bracing? That's pretty small.

It will be peaky and I'd definitely do slot port in this case.

x2. If you make the box larger, 2 4" aeros might work without having to bend them. 3.25 cubes before displacement is definitely going to be too small IMO.

Jacob suggests 2.75 to 3.25. I guess i can do 3 after displacements.

to be honest, i dont have the skill to build a slot ported box. I might be able to do sub forward to the passnger side and 2 4" ports forward to the drivers side.

This is an extended cab truck BTW.

Sounds like you are hurting for space. But why do you think you don't have the skills to build a slot port? its not that hard. you can get lowes to cut all your cuts. You just need a design and then put together.

I have over 14 cubic feet of useable space with me seats all the way back. Im good on space. I just dont want to build my box too big and have issues. I guess 3.25 before displacements with 2 4"s. Ill plan it tomorrow. How do i figure out port displacement again ? lol.

Two full length 4" aeros is right around .28ft^3.
