Hifonics BRW12D4 12" Dual 4-Ohm Car Subwoofer

The Hifonics BRW12D4 is a 12-inch component car subwoofer designed to add dedicated low-frequency output to a vehicle audio system. It is intended for listeners whose factory or full-range speakers do not provide the depth and impact they want from bass-heavy music. As a component subwoofer, it requires a separate enclosure and external amplifier.

This Brutus-series model uses dual 4-ohm voice coils, giving system builders wiring flexibility when selecting a compatible mono or multi-subwoofer amplifier setup. Its listed maximum output is 2,000 watts. The dual-coil configuration should be matched carefully to the amplifier's supported final impedance.

The BRW12D4 uses a vented aluminum former around its 3-inch voice coil. This arrangement is designed to promote heat exchange around the coil during operation. Managing heat is important in a subwoofer system because it supports more consistent operation when the driver is used at higher output levels.

A dual poly-cotton spider with double centering works with the pressure-treated, double-stitched ribbed foam surround to support controlled cone movement. These suspension components are designed to help keep the woofer's piston motion linear. The result is a construction approach focused on stable excursion and reduced mechanical stress.

For an upgrade path, the BRW12D4 fits custom systems built around a dedicated subwoofer enclosure and properly matched external amplification. Its heavy-gauge, powder-coated aluminum die-cast basket and vented motor assembly are intended for the demands of a purpose-built bass system. Confirm enclosure dimensions, amplifier capability, wiring configuration, and vehicle space before installation.

Key Features

• 12-Inch Component Subwoofer: Adds dedicated bass reproduction to a custom car-audio system.
• Dual 4-Ohm Voice Coils: Provides wiring options for compatible amplifier configurations.
• 2,000-Watt Maximum Output: Supports use in higher-output bass system designs.
• 3-Inch Vented Aluminum Former: Helps exchange heat around the voice-coil assembly.
• Dual 70-Ounce Magnets: Forms part of the vented high-energy motor assembly.
• Dual Poly-Cotton Spiders: Supports controlled cone movement with double centering.

Design & Installation

The BRW12D4 is built on a heavy-gauge, powder-coated aluminum die-cast basket with back venting. Its design also includes a vented high-energy motor assembly, dual 70-ounce magnets, a pressure-treated double-stitched ribbed foam surround, and dual poly-cotton spiders. These materials and ventilation features support the driver structure and thermal management.

Install this component subwoofer in a suitable subwoofer enclosure and power it with an external amplifier. Wire both 4-ohm voice coils according to the amplifier's approved load range, and use an enclosure that physically accommodates the woofer and motor structure. Professional installation or careful verification of polarity, final impedance, enclosure fit, and amplifier settings is recommended.
