I'm gonna be doing a small systrm in one of my regular cab trucks and I don't have much room behind the seat. Maybe 1.5cu ft. and I am considering a dd 1508 or 1008. I am wanting a vented box and be capable of being audibly loud in the 30-48hz region. I am curious as to what people run them in box spec wise and if they are capable of playing 30hz pronounced and not sound like air.

Dd guys give me some info please.
