Personally I like the Bose set up my car came with including the rear tray set up. Properly using the volume, bass and treble controls produces pleasing if not arena loud sound.

Yes, the space behind the sub must be vented so the diaphragm can move freely without reverse pressure waves f**king it up. The size of the vent will depend on the size of the sub and its maximum coil excursion. A couple of 3" diameter vents will probably be sufficient for a 10" sub. BTW, a sub is NOT really for bass. It's for near-subsonic and subsonic audio, which includes "thumping." Smooth bass can be achieved with drivers as small as 5 inches. Getting the crossover network to make a good transition from subsonic to actual bass can be tricky. Done badly, it does sound awful.
