    Either make the box larger or make the port longer.

    However, seeing as neither of these are ideal, a new box would be better from all standpoints.

    Are you talking about a 4" round port? If so, your numbers are going to be different...

    Seems like a miscommunication, Lemans is talking about a slot port while Big-Cat is talking about a round port (seems to be so...)
