Customization with Boston Acoustics G3 Subwoofers

Boston Acoustics' G3 series subwoofers provide deep, crisp, responsive, and quality bass that has come to be expected from a high-end company like Boston Acoustics at an affordable price. Featuring Soft Part System (SPS™) technology that will allow the removal of soft parts in case of an impedance change when adding more subs, repair if the voice coil fails and is damaged, and it also allows for customization by allowing the basket and back screen to be removed from the motor structure. This will then allow the option to paint, chrome, or even powder coat to make your subwoofer really stand out. G3 series subwoofer also feature SureSet™ impedance selection that makes wiring easy and accurate as well as adds protection from overdrive to the voice-coil, and a RadialVent® cooling system that decreases heat dissipation as well as distortion cause by thermal discharge. This improves the subwoofer's ability to perform at higher power handling levels while still producing quality bass output. G3 series subwoofers are versatile, dependable, loud, and affordable making them an easy selection for any car audio system.
