16 square inches of port area per cubic foot of box volume, make the port 18-20 inches deep. The port is tuned to the box volume, not the subs. This generally tunes the box to the upper 30Hz area, with the vehicle transfer function extending the frequency another 10-12Hz or so.

How does Port length affect sound?

Longer port = lower tuning. Shorter port = higher tuning. What tuning to use depends on several factors (speaker, box, what kind of response curve you’re going for, etc.) and it significantly changes the sound.
