    9 times out of 10 a ported box will need to be larger in volume than a sealed box, so you might want to take that into consideration.
    PVC is fine for ports, keeping in mind the inner diameter is the useable port volume. Ideally the lower profile the PVC would be better because it doesnt take up as much displacment. You can look into Aeroports, which is basically a domesticated PVC for boxes that comes with flared ends rather than a straight cut.
    IMO a slot port is easier because you can make different ports for different tunes. You can t-nut the box and change them in and out on demand.
    Until the last year or so I always ran sealed, because I was ignorant on how much better the subs performed in a ported box. I dont think ill go sealed again.

    so if i choose the thinnest PVC there shouldn't be a problem with it flexing?

    Im not really going to go out on a limb and say yes, get the thinnest, but yes within reason. If your on your way out and the thing is flexing and waving in the air, Id have to say get one a little thicker. I wouldnt forsee PVC flexing on you.
    Where you at in Texas?
    You can find those aeroprts on Ebay for pretty cheap, you just cut them to size and pop the ends on.

    If you can get the aero ports for a decent price, get them. I had a pair of 4" and liked them very much.
