A good subwoofer will bring the bottom octave of your music back into proper balance, so you'll hear familiar tunes in a whole new light. It'll take a load off your full-range speakers too, since you'll be playing your tunes with the bass control set at "0" instead of "+5".

Some people get turned off by subs throbbing next to them at traffic lights, but it's not just about the boom — you can adjust any subwoofer to fit your tastes and your vehicle. And once you drive with a subwoofer, you can never go back to living without one. Or two.
