Sa-8 4" aero?

[Bob345 39]

Ok so I am helping my friend build a system for his truck and we are planing on doing one of those under seat enclosures. I wanted to know if just one or two 4" aero ports will be enough to let the sa-8 breath. I think two would work great but my friend wants me to get a second opinion.

It should be sufficient from my calculations.
