My dad has an E8v1 in his van in an old box that was from a component set, he needs a new box. I have leftover wood from my box so I thought I might as well use it! Using sundowns recommendations I figured .6 cubes with a 7x2 PVC aero port. My question is how much port area should it have and what frequency to tune to. He listens to rock music, should I even port it?

I would port it. I think they mean use 2" PVC 7" long. Don't forget to subtract the port and driver displacement.
