you will probobly want at least 1.4 or so cubic feet if you want a ported box for that sub. Are you sure you want ported though? What kind of music do you listen to? You would be able to use a smaller box if it was sealed.

really, you do have a small trunk already you might want to go with sealed just for space. for most sub boxes you use a 3/4" mdf board. with a good sealant and super glue or screws.

If you need trunk space then go with a sealed, besides it will sound better. Ported boxes require more airspace so they can be consideribly bigger. Build a sealed box 14x14x14 and fill it with polyfil, it will sound good and you will hear it fine.

That woofer works best in a 1.5 CUFT ported enclosure. That's more like 15X15X16. It's rated at 175 watts RMS and to 25Hz.
