No system is complete without a bazooka tube or subwoofer. Car subwoofers (or subs), will add astonishing sound to your vehicle. At MobileSoundWorks.com you’ll find car subwoofer models that are capable of emitting earth-shattering lows. A sub can reproduce frequencies below the normal range of standard car speakers. If you take a quality subwoofer with the right amount of power and insert it into a compatible enclosure, it’ll play LOUD enough to add real impact to your music! We recommend using a monoblock amp to drive your sub(s).
