Gravity G3-10D4 10" Dual 4-Ohm Car Subwoofer

The Gravity G3-10D4 is a 10-inch car audio subwoofer designed to add dedicated low-frequency output to a vehicle sound system. It is intended for listeners building or upgrading a system that needs more bass extension than full-range speakers can provide. Its dual 4-ohm voice-coil layout gives installers useful wiring flexibility when matching the subwoofer to a compatible amplifier.

With a rated frequency response of 30-500 Hz, the G3-10D4 is built to cover the bass range while integrating with the rest of a car audio system. Its 750-watt RMS and 1,500-watt peak power ratings provide a clear starting point for amplifier selection and gain setup. Careful power matching remains important for dependable operation and controlled bass performance.

The subwoofer uses a competition-grade pressed paper cone paired with a high-roll foam surround. This combination is designed to provide a rigid moving surface and the excursion capability needed for low-frequency reproduction. The foam surround also supports the cone through repeated movement during normal use.

An advanced airflow cooling design helps manage heat around the voice-coil assembly during extended playback. Thermal management is especially relevant in high-output systems, where sustained amplifier power can raise operating temperatures. The G3-10D4 is therefore suited to installations that prioritize a dedicated bass driver with serviceable wiring options.

This is a component subwoofer, so it should be installed in a properly selected enclosure and powered by a separate compatible amplifier. It can be used as a single-subwoofer upgrade or as part of a multi-subwoofer system. Enclosure selection, final wiring impedance, amplifier capability, and vehicle space should all be confirmed before installation.

Key Features

• 10-Inch Subwoofer: Adds a dedicated bass driver to a vehicle audio system.
• Dual 4-Ohm Voice Coils: Supports series or parallel wiring choices with a compatible amplifier.
• 750-Watt RMS Rating: Provides a continuous-power reference for amplifier matching.
• 1,500-Watt Peak Rating: Indicates short-term maximum power handling.
• Pressed Paper Cone: Uses a competition-grade cone material for bass reproduction.
• Airflow Cooling Design: Helps manage heat during extended high-output playback.

Design & Installation

The G3-10D4 combines a pressed paper cone, high-roll foam surround, dual voice coils, and an airflow-focused cooling design. Its 10-inch format is intended for conventional car-audio subwoofer enclosures. The design is focused on dedicated low-frequency reproduction rather than full-range speaker duty.

Use an enclosure designed for a 10-inch subwoofer and verify all physical fitment details before cutting or mounting, as manufacturer mounting dimensions were not confirmed. The two 4-ohm voice coils may be wired in parallel for a 2-ohm nominal load or in series for an 8-ohm nominal load. Select an amplifier that is stable at the chosen final impedance, use appropriate wiring, and set gains conservatively to match the subwoofer's 750-watt RMS rating.
