My names dustin.lol i think you could get away with three cubes each.my 12 hdc3s are in 2.3 each. I had a box design for two hdc3 15s somewhere ill see if i can find it
My 2 hdc3 12s are in a 4.6 cuft with 73cuin of port tuned to 32hz. I tried 4.3@36hz and 5.5@38hz before hand. all designed by mike at AQ. 4.6@32hz takes the cake in my setup.( In a trunk sealed off into cabin). Diff
experiences diff installs. Good luck OP in deciding ur system bro
The AQ and big box theory is not exactly true, also with the high tuning thing. I like mine in a smaller lower tuned box then recommended. Pretty sure theres a thread discussing that issue also. But its all up to the listener and install dependent. They're real peaky in big higher tuned boxes.
You wont be dissapointed
you do realize that this is the DC section right?
Didnt realize. didnt look. Just trying to help out. Is mentioning other brands is against the rules? Im not bashing dc Just putting suggestions out there nothin wrong wit dc at all CS is great. But AQ is too. 2 things i love about both
To start yes. But you would want to upgrade to 2, 2kw amps to get them really moving but the hdc3s are efficient 2 18s on 2kw will get loud as hell still, assuming your box is built/designed correctly.
Just be careful with your gains. Btw if i was you just get one more lvl 3 since you already got it. But if not AQ hdc3s are loud as shit if all you want is loudness thats what i run. And their cheap for what they can do.
