Porting a 5 cube box for 2 pioneer 12"

It's going in a nissan frontier and the subs are the TS-W126DVC.

Were wanting to do the box in this style to slant behind the seat..

But were stumped on how to make the port.. We want a verticle slotted port in the middle tuned @34. How wide should it be and how far should it go back? I can't find a box cal that will calculate the port length for this style of box.. Any ideas?

Noone? Were building as we speak.. Need input!

Come on.. Noone has ever built a slanted ported box?

You could do aero ports on the sides i think.

edit-slot port..no idea

Just find the volume you have with the slant and figure out rectangle dimensions that give you the same volume and put that in a box calc. That should tell you port length, vol., etc.

Good idea, I don't wanna do ports on the side.. I either want the port from top to bottom in the middle or all the way across the bottom.. But if i did it accross the bottom how far do I extend it back and then up? This is where i'm confused..

all the way across the bottom will probably be too big of a ratio

But if i don't do it all the way accross I will have to find some way to support the bottom part of the L right? I can't just do a very thin port accross the bottom?

just build a square port and put it in the top of the box like you want to

But i can't just come straight down with a piece of wood because the front angle is at like 67 degrees.. By making a square port do you mean just making a square as far down as the length calls for?
