Perfect! I will be doing 4 in 5cu net each/20cu net total on 2 SAZ3500v.2's tuned about 32/33hz in a no wall for my Suburban

What's the biggest the 12s could be in?

We've gone up to 3 cubes -- but you do sacrifice some mechanical handling.

Okk because I would only plan to add around 1100 rms to them. I can make it as big as 3.2 cubes.

I'm trying to help a guy design an enclosure for an X series 15.  What is the mounting depth on the sub?  Do you have that information posted elsewhere?

 

 

EDIT:  Nevermind, reading is obviously outside my abilities today.  Another scan through the topics in the section found the thread I was after.
