Gravity G3-12D2 12" Dual 2-Ohm Car Subwoofer

The Gravity G3-12D2 is a 12-inch car audio subwoofer designed to add dedicated low-frequency output to a vehicle sound system. It is intended for listeners who want bass reproduction beyond what full-range door or rear-deck speakers typically provide. Its dual voice coil design gives system builders flexibility when planning an amplifier and wiring configuration.

With a 1,000-watt RMS power rating per subwoofer and 2,000-watt peak power rating, the G3-12D2 is suited to amplified bass systems that are matched carefully for power and impedance. Its rated 30 to 500 Hz frequency response focuses on the bass and upper-bass range. The 87 dB sensitivity specification provides a useful reference when comparing it with compatible subwoofers and amplifier plans.

The G3-12D2 uses a competition-grade pressed paper cone and a high-roll foam surround. This combination is designed to support cone movement while maintaining the subwoofer's intended structure during use. An advanced airflow cooling system is included to help manage heat around the motor and voice-coil assembly.

Each G3-12D2 uses dual 2-ohm voice coils, allowing installers to account for the amplifier's stable load capability when choosing a wiring arrangement. Proper amplifier selection, enclosure design, and gain setup remain important for dependable operation. This makes the model a practical choice for custom car-audio installations rather than a direct replacement for a factory full-range speaker.

Use the G3-12D2 as the low-frequency foundation of a system with an appropriate mono or multi-channel amplifier, enclosure, wiring, and crossover configuration. It can be used as a single-subwoofer installation or as part of a matched multi-subwoofer system. Confirm available mounting space and amplifier impedance compatibility before purchase and installation.

• Airflow Cooling System: Helps manage heat during extended amplified use.

Design & Installation

The G3-12D2 combines a pressed paper cone with a high-roll foam surround and dual voice-coil construction. Its design also incorporates an advanced airflow cooling system. The subwoofer is built for car-audio bass applications and measures 12 inches in nominal diameter.

Install the G3-12D2 in a properly sized and securely mounted subwoofer enclosure, using an amplifier that is stable at the final impedance created by the selected voice-coil wiring. Set crossover, gain, and bass-boost controls conservatively to match the rest of the system. The package is listed as containing one G3-12D2 subwoofer; confirm required enclosure, amplifier, wiring, mounting hardware, and accessories separately before installation.
