I need a box designed for the above subwoofer, with one or two (whichever allows the smallest box) 4 inch aeroport(s), I can build the box, I am just very new to designing. I have a diagram of the backseat of my car, and would like the port to fire right above the subwoofer and both into the cabin like so:

that space in the middle will be exposed as there is an armrest in the seatback that will 99% of the time be opened. if someone could just give me some numbers for port length, and box size I can figure out how to build and design it based on learning those numbers.

I would assume this is a pretty basic calculation, but I have no idea how to find it and calculate what I need.
