Find the Sd in the T/S parameters posted by Kicker.

Unless you're talking about for port area for an enclosure.

You actually don't want the port to be have the same cross sectional area as the subs. Having too much port area can actually hurt SPL.

Are you talking about 100 per sub because they have 200 on both of them right now and its only at 149.1 on term they need to get louder they have enough power on them to. I need them louder I want that 150 or more.
