Gravity G3-8D2 8" Dual 2-Ohm Car Subwoofer

The Gravity G3-8D2 is an 8-inch car audio subwoofer designed for systems that need bass output in a compact speaker format. Its dual 2-ohm voice coil arrangement provides wiring flexibility when matching the subwoofer to a compatible amplifier. This makes it a practical option for installations where enclosure and mounting space are limited.

This model is rated for up to 1,000 watts of peak power. It is intended to reproduce low-frequency content for a fuller, more grounded sound in a car audio system. An appropriately matched amplifier and enclosure are required for operation.

The G3-8D2 uses a pressed paper cone intended for car audio bass reproduction. A high-roll foam surround supports cone movement while providing a flexible outer suspension. These materials are specified as part of the subwoofer's competition-grade construction.

An advanced airflow cooling design is listed for the G3-8D2. This design is intended to help manage heat during extended playback. The subwoofer also uses a high-flux motor system to support its low-frequency performance.

With its 8-inch diameter and dual 2-ohm coils, the G3-8D2 can fit into a compact subwoofer upgrade path when paired with compatible equipment. It is suited to listeners building or updating a dedicated bass section in a vehicle. Confirm enclosure requirements, amplifier stability, available mounting depth, and final wired impedance before installation.

Design & Installation

The Gravity G3-8D2 combines a pressed paper cone, high-roll foam surround, and high-flux motor system. Its construction is designed around compact 8-inch bass reproduction, with an airflow cooling system listed as part of the design. The dual voice coil configuration is a central part of its electrical design.

Use the G3-8D2 only with an amplifier that remains stable at the final impedance created by the chosen voice-coil wiring. Install it in an enclosure designed for the subwoofer after confirming the required cutout, mounting depth, and enclosure recommendations with the manufacturer or seller. Speaker wire, an enclosure, an amplifier, and installation hardware are not confirmed as included.
