Cerwin-Vega V8DV4 8" Dual 4-Ohm Voice Coil Subwoofer

The Cerwin-Vega V8DV4 is an 8-inch car audio subwoofer designed to add dedicated low-frequency output to a factory-upgrade or custom sound system. Its dual 4-ohm voice coil configuration gives installers flexibility when matching the subwoofer to a compatible amplifier. This model is intended for listeners who want a compact subwoofer with substantial continuous power handling.

With an 800-watt RMS and 2,400-watt maximum power rating, the V8DV4 is built for systems that need stronger bass than full-range door speakers can provide. Its 85 dB sensitivity and 53 Hz resonant frequency describe a design focused on powered subwoofer applications. A properly selected amplifier, enclosure, and installation are required for operation.

The V8DV4 uses a hybrid carbon fiber and polypropylene diaphragm to combine stiffness with controlled cone movement. A stitch-reinforced Santoprene surround supports the cone during excursion. Cerwin-Vega specifies 6.5 mm of Xmax for this model.

A ferrite motor structure supplies the magnetic force behind the subwoofer, while the cast aluminum basket provides a rigid mounting foundation. The 2.5-inch voice coil is paired with a vented pole-piece design intended to support cooling during extended playback. These construction elements are designed for demanding bass reproduction in a vehicle environment.

For system integration, the V8DV4 includes Cerwin-Vega's single-terminal impedance selector for its dual voice coils. The dual 4-ohm design can present either a 2-ohm parallel load or an 8-ohm series load, depending on the selected wiring configuration. This makes it suitable for a compatible mono amplifier or for use as part of a larger multi-subwoofer design.

Key Features

• 800W RMS Power Handling Supports use with a suitably matched subwoofer amplifier.
• Dual 4-Ohm Voice Coils Provides 2-ohm or 8-ohm wiring-load options.
• Single-Terminal Impedance Selector Simplifies voice-coil configuration at the subwoofer.
• Hybrid Carbon Fiber/Polypropylene Cone Balances cone rigidity with controlled bass output.
• Santoprene Surround Supports repeated cone movement during playback.
• Ferrite Motor Structure Provides the magnetic force needed for subwoofer operation.

Design & Installation

The V8DV4 combines a cast aluminum basket, ferrite magnet, carbon fiber/polypropylene diaphragm, and stitch-reinforced Santoprene surround. Its vented pole piece is designed to aid cooling, and the 2.5-inch voice coil supports its rated power-handling design. The subwoofer measures 8.72 inches in overall diameter and has a 5.43-inch mounting depth.

Confirm that the enclosure has at least a 7.48-inch cutout and enough behind-panel clearance for the 5.43-inch mounting depth and terminals. Use an amplifier rated to operate safely at the selected 2-ohm or 8-ohm load, and connect both voice coils through the model's impedance-selector arrangement. An enclosure and amplifier are separate system components and should be chosen according to the vehicle, available space, and amplifier capabilities.
