there are tons of ways, just all depends on how much you are willing to sacrifice.
if you are not trying to have a bad ass theater system then just put it behind your TV (assuming its a projection/large tv or you have an entertainment system in corner)
if you have the money/time, do an in wall installation. if there is a closet in the room or if theres an attic above you you basically (and i mean VERY basically) just cut a whole for the sub in the wall and fire the little guy up.
