4th Order BP for 2 18"s

You're right, 2 cubes per works best for 18s sealed for SPL.
In my old truck though with the 4 18s we did 2.25/2.5 per sub and it would play 30 hz like a freak and the subs barely moved.

Would bass race a 161 and change with 8 Autotek 3000s
That build is on termpro right? I think I seen it there.

 
Is this a joke?
Nope, no bs 161.91db @ 48hz and a 157.85 @ 60hz. I had a competition with about 12 friends (split in teams of 3) and we all came up with our own designs and 2 runs. The best wasnt mine, I didnt have enough port area. The best was a 163.2 .

Oh and if you still dont believe it, I got a hell of a reference to vouch. Our moderator was, Joe P. MECP Master Installer and co-author of the Master Study Guide.

Cool, I believe you. I'm gonna shoot you a pm with some questions and stuff if you'd be willing to help me out.
