I will be fiberglassing an enclosure for my SA-15 into the spare tire well, but don't know if it will be happy in a sealed box. I listen mainly to hip hop and occasionally rock, so I want it to hit those low notes with some authority, but seeing as it has such a high F3 I'm not to sure if it will do that. Also seeing everyone else who picks up one of these ports it, I don't want to build a sealed enclosure to find out that it isn't what I want. I'd like to go sealed to make the install easier since it'll be my first time fiberglassing and building a box, and to save a little room and keep the design much simpler as I would like to maintain as much hatch space as I can.
