Just got my hdc3 in the other day and could use some opinions. The current box is a little under 4 cubes at 30 with not nearly enough port area. I have heard these subs like bigger boxes with lots of port area. You guys think 4.5 cubes at 32 would be good for this sub? Might do a 6 or 8 inch sonotube port, if not just a normal slot port. Im going to try sub up on the drivers side with the port side firing to the passenger side. Any help or suggestions would be appreciated.
