Gravity G5-12D 12" Dual 4-Ohm Car Subwoofer

The Gravity G5-12D is a 12-inch car audio subwoofer designed to add dedicated low-frequency output to an aftermarket sound system. It is suited to listeners building a bass-focused upgrade with a separate amplifier and enclosure. Its dual 4-ohm voice-coil configuration gives installers flexibility when planning an amplifier load.

Rated for 750 watts RMS and 3,000 watts maximum power, the G5-12D is intended for systems that require sustained bass handling rather than relying on full-range speakers alone. Its specified 30 Hz to 500 Hz frequency response covers the bass and upper-bass range commonly assigned to a subwoofer. An 87 dB sensitivity rating provides a useful reference when matching the driver with suitable amplification.

The subwoofer uses a competition-grade pressed-paper cone and a high-roll foam surround. This material combination is intended to support controlled cone movement while maintaining the durability needed for mobile-audio use. The design is finished in black and uses a flush-mount installation style.

An advanced airflow cooling system is specified to help manage heat during extended operation. This is particularly relevant when the subwoofer is driven near its continuous power rating in a properly designed system. As with any high-power subwoofer, clean amplifier power and correct gain adjustment are important for dependable operation.

The G5-12D can be used as the foundation of a single-subwoofer system or paired with a compatible second driver in a larger build. Because it is a passive subwoofer, it requires an external amplifier, appropriate enclosure, wiring, and crossover setup. Its dual 4-ohm coils should be wired only in a configuration that the chosen amplifier is designed to support.

Key Features

• 12-Inch Subwoofer: Adds dedicated bass capability to a car audio system.
• 750W RMS Handling: Supports sustained power when matched with a suitable amplifier.
• Dual 4-Ohm Voice Coils: Provides wiring flexibility for compatible mono amplifier setups.
• Pressed-Paper Cone: Forms the primary moving surface for bass reproduction.
• High-Roll Foam Surround: Supports cone travel and complements the durable driver design.
• Airflow Cooling System: Helps manage heat during longer listening sessions.

Design & Installation

The G5-12D combines a pressed-paper cone with a high-roll foam surround in a black, flush-mount subwoofer design. Its specified cooling arrangement is intended to support thermal management during operation. The driver is designed for car audio use and is supplied as a single subwoofer unit.

Install the G5-12D in an enclosure designed for a 12-inch subwoofer, then power it with an external amplifier selected around its 750-watt RMS rating. Verify the final impedance created by the two 4-ohm voice coils before connecting the amplifier. Use a low-pass crossover and follow the enclosure, wiring, and amplifier manufacturers' instructions for system setup.
