Hifonics BRW10D4 10" Dual 4-Ohm Car Subwoofer

The Hifonics BRW10D4 is a 10-inch component car subwoofer built to add dedicated low-frequency output to a vehicle audio system. It is intended for listeners who want more bass depth and impact than typical full-range car speakers can provide. Because it is a component subwoofer, it requires a separate enclosure and an external amplifier.

This Brutus-series model uses a dual 4-ohm voice-coil configuration for system-design flexibility. Its listed 1600-watt power handling supports use in higher-output bass systems when paired with an appropriately matched amplifier. The dual-coil layout lets an installer select a final wiring load that is compatible with the amplifier being used.

The BRW10D4 is engineered around a vented aluminum voice-coil former and a 3-inch voice coil. The vented former is designed to exchange heat during operation, helping manage heat buildup at the voice coil. This construction supports sustained bass playback while prioritizing controlled piston movement.

A pressure-treated, double-stitched ribbed foam surround works with a dual poly-cotton spider assembly. The double-centered spider design is intended to help keep cone travel linear under power. Together, these parts support the subwoofer's moving assembly during bass-heavy listening.

For a complete upgrade, install the BRW10D4 in a correctly built subwoofer enclosure and power it with a compatible external amplifier. Its heavy-duty basket and vented motor structure make it suited to custom trunk, hatch, or cargo-area bass systems. Select the enclosure, amplifier output, and wiring configuration as a matched system rather than treating the subwoofer as a direct replacement for a full-range speaker.

Key Features

• 10-Inch Component Subwoofer: Adds dedicated bass reproduction to a custom car audio system.
• Dual 4-Ohm Voice Coils: Provides wiring flexibility for compatible amplifier loads.
• 1600-Watt Listed Power Handling: Supports use in higher-output amplified bass systems.
• 3-Inch Vented Aluminum Former: Helps exchange heat around the voice-coil assembly.
• Dual 70-Ounce Magnets: Forms part of the high-energy motor assembly.
• Dual Poly-Cotton Spider: Helps support centered, controlled cone movement.

Design & Installation

The BRW10D4 uses a heavy-gauge, powder-coated aluminum die-cast basket with back venting. Its moving assembly includes a pressure-treated double-stitched ribbed foam surround, dual poly-cotton spider, vented aluminum former, and dual 70-ounce magnets. These components are designed for a durable installation in a car-audio subwoofer enclosure.

This is a passive component subwoofer, so an enclosure and external amplifier are required for operation. Wire its dual 4-ohm coils according to the amplifier's approved impedance capability, and use an enclosure designed for the selected system goals. Confirm mounting clearance, enclosure volume, and amplifier compatibility before installation.
