Ok im tuning to 40hz and plan to run 3 3" aero ports and I figured around 17 or so long, so How much space should I take out for the sub and ports?
I know the sub is around .25 cubes but the I came up with about another .25 or so with port area..
Am I pretty close here?

My plan was to be at around 1.6 after sub and ports.

thank God! i hope you like'm.

you can calculate the area the ports take by taking the outside diameter and cutting it in half for radius. then its just pi*r*r*port length*3 (since u have 3 ports and they should be the same length)
