I just got a hd3 15 and I need to build a box for it. I know on the audioque site it says 4.5 cu/ft but they don't give any port info. I've been told that I should tune this sub low so should I build a bigger box that 4.5cu/ft? If so what size and how much sq inches of port area should I use. I drive a 99 yukon, so it's a big truck, and I listen to all kinds of music. I'm trying to go for a good mix of spl and sq. I'm up for suggestions.
