GRAVITY G7-12D2 12" Dual 2-Ohm Car Subwoofer

The GRAVITY G7-12D2 is a 12-inch car audio subwoofer designed to add dedicated low-frequency output to a vehicle sound system. It is intended for listeners building a bass-focused upgrade with a separate compatible amplifier and enclosure. Its dual 2-ohm voice coil design provides wiring flexibility when matching the subwoofer to an amplifier.

This model uses a competition-grade pressed paper cone and a high-roll foam surround. That combination is designed to support controlled cone movement while reproducing bass-heavy music. The published frequency response is 35 Hz to 500 Hz, covering the low-frequency range typically assigned to a subwoofer.

The G7-12D2 carries a published peak-power rating of 4,800 watts per subwoofer. Because peak ratings are not the same as continuous amplifier requirements, amplifier selection should be based on compatible impedance operation and conservative gain setup. Proper tuning helps keep bass output clear and reduces the chance of audible distortion.

An advanced airflow cooling system is part of the subwoofer's listed design. This feature is intended to help manage heat during extended listening sessions. The listed sensitivity is 88 dB, and final output will also depend on the enclosure, amplifier power, vehicle acoustics, and installation quality.

The G7-12D2 is a bare subwoofer rather than a complete powered bass system. It is suited to custom sealed or ported enclosure projects where the installer can choose the box style and wiring arrangement. With its two 2-ohm voice coils, it can be wired for either a 1-ohm or 4-ohm final load when both coils are used correctly.

Key Features

• 12-Inch Subwoofer: Adds dedicated low-frequency reproduction to a custom car audio system.
• Dual 2-Ohm Voice Coils: Supports series or parallel wiring to suit compatible amplifiers.
• 4,800-Watt Peak Rating: Published peak power handling per individual subwoofer.
• Pressed Paper Cone: Provides a purpose-built cone material for bass reproduction.
• High-Roll Foam Surround: Supports cone travel while helping maintain a durable edge suspension.
• Airflow Cooling System: Helps manage heat during extended high-output operation.

Design & Installation

The GRAVITY G7-12D2 uses a competition-grade pressed paper cone, high-roll foam surround, and dual voice coil motor structure. Its design is intended for installation in a vehicle-specific or custom-built subwoofer enclosure. The subwoofer is listed for car-audio use and requires an enclosure for mounting.

Use an amplifier that is stable at the final impedance created by the selected wiring method. The two 2-ohm coils can be wired in parallel for a 1-ohm load or in series for a 4-ohm load; never connect the subwoofer until the amplifier's supported load is confirmed. Secure the driver to a properly sealed enclosure, use adequately sized speaker wire, and set amplifier gain and low-pass filtering carefully to avoid distortion.
