I got a pair of these and have a question about a box. I really want a ported box, but don't have the room. They are going in a 350Z and i still need trunk space. what do you think about a sealed box? What size would be ideal? Below is a link where i have some pics. http://www.caraudio.com/forums/enclosure-design-construction-help/574003-help-ported-box.html
