Right now I'm thinking 15 cuft tuned to 32hz. Anyone have any other experiences with HDC3's? This is going in a car btw. Anyone able to suggest ways to figure out and take into account my cars resonance?

box is too big and tuning too low...

For a daily set up with 1-2k per sub 8 - 8.5cubes @ 38Hz works quite well. If you play a lot of C&S music then consider tuning to 35Hz...

I'll be sending about 2200 per sub. Really thats too big? I was trying to get it so the 30hz range was noticeable.

From what I have seen and heard about the subs, they have no problem playing lows even with a 40hz tune.

Skip01 had (4) 12" HDC3s on about 10k tuned to 40hz. One of his vids on youtube shows him murdering the lows on Jeezy's "White Girl".

Mlstrass advice is very solid, he has worked on alot of Audioque/Digital Design setups :fyi:

I'd do 8.5cubes with 136^2 of port area tuned to 35Hz. Should be a low end monster...
