I will go ahead and say use this as your criteria.

Sealed box = if you want something that wont take up so much room

Ported = if you have the room to spare for the huge box, and you want that extra 3db that is claimed from using a ported over a sealed box.


If you have an Integra, I dont know if you would want a ported box for a 15" woofer in the hatch area.
