You could do 2 aeros through the rear shelf where the rear suround should be

so how do I know how much port to add? Like do I take the dimensions of the ported section and tune it like I would a regular ported box in the torres calculator?

pretty much. but don't tune as low.

the more port area (usually) the better. so shoot for 15+ inches per cube.

tune higher, 47+

Alright cool I'm thinkin right now I might make the port 8W x 8H x 12L including the 3/4 of the mdf so technically 6.5W x 6.5 H so that gives me about 42 sq in of port if my calculations in my head are right lol so thats not too bad right? Or is that too little port?

make the port shorter. if you tune that low, you're gonna need one hell of an impressive mid stage to compensate for the roll off

Here is a pic of what your baffle should look like:

I couldnt find a picture of a removable port but I think you will get the idea.

Hows this look guys I'm sure you can figure it out but blue = fixed baffle, Green = the two fixed side pieces that will be flush with the removeable port and the red is of course the removeable port that I resized to 8W X 8H X 12D

That will definetely get the point across.

Was talking about how earlier in the topic, people where having a hard time explaining the removable port, that model set would make the point get a cross a lot easier.
