Decided to get a professional box made by my friend who is a master installer... since i am no fabricator. What is the recommend port dimensions for these subs? I emailed jacob but I figured I'd post here. Would like to get started on it today. Should I do 2 seperate chambers? 2 ports , 1 with each sub.

That's much more complicated, but if you want to. Stick to 12-16 square inches of port area per cubic foot. I personally did 15 square inches per cube ant it's worked well for me.

We need max outside dimensions of the box you want to build to get a better idea on port size!

1.5ft with around 18" of port area per sub tuned to 32-36hz. You'll love it.

1.5ft of net volume per sub for an sa-12.
