I would use at least 250 Square Inch port for that many 18" woofers.

As for dimensions, its hard to say with out knowing what your box dimensions are. But based off GROSS volume (20 cubes) it would need to be aprox. 24 inches long for a 30hz tuning.

20 cubes before displacement will be pretty small for 4 18s, triple 18s or 4 15s in that space if you want lows.
