Gravity G12BD2 Dual 12" Ported Loaded Subwoofer Enclosure

The Gravity G12BD2 is a dual 12-inch loaded car-subwoofer enclosure designed to add low-frequency output to a vehicle audio system without building a custom box. Its two subwoofers are pre-installed in a ported enclosure and wired to an 8-ohm final load. This makes it a practical option for installers seeking a ready-made enclosure format.

The enclosure is rated for 800 watts RMS and 1,600 watts peak power handling. Its published frequency-response range is 30 Hz to 1.5 kHz, with the ported enclosure tuned to 30 Hz. The design is intended to emphasize low-bass reproduction in a trunk or cargo-area installation.

Gravity identifies the G12BD2 as part of its Warzone Series. The system uses two 12-inch drivers in a vented, wedge-style enclosure with 4.00 cubic feet of stated air space. The pre-wired 8-ohm configuration helps define the amplifier load that the rest of the system must support.

The enclosure uses heavy-duty MDF construction, giving the assembled unit a rigid cabinet structure for its installed drivers. At 34.5 inches wide, 19.5 inches high, and 18.75 inches deep, it is suited to vehicles with sufficient cargo-space clearance. Measure the intended location and account for space around the enclosure before purchase.

Online listings describe the G12BD2 inconsistently as both a loaded enclosure and an active powered enclosure. The confirmed technical details specify pre-loaded subwoofers and an 8-ohm final impedance, but do not publish amplifier specifications. Confirm the supplied amplification configuration and connection requirements with the retailer before planning the wiring installation.

Key Features

• 1,600W Peak Rating: Provides a published 1,600-watt peak power-handling rating.
• 8-Ohm Final Load: Pre-wired enclosure presents an 8-ohm final impedance load.
• Ported Cabinet: Vented enclosure is tuned to 30 Hz.
• Heavy-Duty MDF: MDF enclosure construction provides a durable cabinet foundation.

Design & Installation

The G12BD2 uses a wedge-style, ported enclosure made from heavy-duty MDF. Its stated internal air space is 4.00 cubic feet, and the ported layout is tuned to 30 Hz. The two subwoofers arrive pre-loaded in the enclosure and are listed with single voice coils.

Plan installation around the enclosure's 34.5 x 19.5 x 18.75-inch dimensions and confirm that the vehicle has adequate cargo-area clearance. Match the system to the enclosure's stated 8-ohm final load and 800-watt RMS rating. Because published listings conflict on whether amplification is integrated, verify the exact package contents, wiring requirements, and required accessories with the selling retailer before installation.
