I really think aeros would be alot easier to do it with, just do like 3 or 4 then plug a couple of them, or iif they dont end up right its so much easier to either cut them down or put in a new pipe
Look dude, you obviously don't have near enough experience or the skills necessary to design an enclosure as complicated as this. Why don't you do yourself a favor and just pay the $5 it costs to get a design from one of the vets on here?
