Multi sub ported box help

[jhunka23]

Okay so I have a 97 gmc extended cab truck with the back seats taken out. I'm currently running 4 10" type r subs in individual boxes, housed in one larger box. To save on space, and also upgrade, I want to build a poured box for four 12" type r subs. I don't want to have to waste space and make individual boxes however. I'm curious what the best way would be to design the box so its all a singular box with only one port

Sub up port up driver side would be the way to go. How much power you running to them? And what tuning you looking for?

I was planning on a wedge style in my mind, 2 subs up, 2 on the angle. I'm not worried about the amp or wiring, I'm getting 1000w to each sub. I'm more so worried about the box itself. And I'll probably have it tuned to 30-32 Hz I'm thinking

What amp are you using and what are you dimensions? Height x width x depth

The box will be 6.84ft3 internal after I add the sub displacement and any extra space fillers into the equation. My question is based more so on the physical construction of the box. Like if I wanted just a singular port, how do I calculate that for four subs in one box? And do I have to build partial separation walls for each sub or can they share airspace freely.

I have all the space I need to build the proper sized box without restrictions.

It doesnt help. With actual numbers and dimensions we can calculate out a box.

The subs dont need seperate walls, however the port does need clearance to breathe, a few inches or so
