have a single hdc 12 right now, debating heavily on trying to stuff 2 15's in my standard cab dodge. 7 cubes enough for 2 of these? and yes i mean net volume not gross.

hmm anyone? i know someone knows this off the top of their head.

i "think" the displacement is .22 or .23 for some reason but i can't remember. and 3.5 a piece i know thats cuttin it close but is it outside the optimal zone or still in that grey area

I'd go a little larger if you want a more musical and flatter response. The website should have displacements.

they get a little peaky with a box that small

I'd recommend at least 3.75 cubes daily.

I ran 2 in 4cf net but wasn't to good on the lows. looking to do 3.5 for each in the new box

ahh thats what i thought, may do 2 12's have to see how much of my back window i can sacrifice before it becomes an obstruction, if i had the money i'd buy an indash monitor and backup camera and wall the **** thing, plenty of room!

i love my single 12 and for 99% of people it would be plenty, it flexes the whole cab something sick but, I find myself going, if 1 12 on 1500w does that... what would 2 15's do on a sundown 3k or a 40.1 lol

available room update i can pull off 3.7 cubes each, assuming 2 6" ports is sufficient(no sure on that one yet) and that the displacement of the subs is approx .22 ft^3
