Use one end panel of the box for your outer port wall, the port can be on either end of the box and will be 3.2" wide and 22.5" tall and 19" deep measured from the outside face of the box
The port and sub will fire up, The sub will be centered between the inner port wall and the end of the box and front to back of the box.
