Cerwin-Vega V8DV2 8" Dual 2-Ohm Subwoofer

The Cerwin-Vega V8DV2 is an 8-inch car audio subwoofer designed to add dedicated low-frequency output to a vehicle sound system. Its dual 2-ohm voice coil design provides wiring flexibility for matching an amplifier and system load. It is intended for installations that need strong bass from a compact driver footprint.

This subwoofer is suited to enthusiasts building or updating a custom bass system with an external amplifier and enclosure. Its 800-watt RMS power rating calls for an amplifier selected and tuned to deliver appropriate continuous power at the final wired impedance. Both voice coils should be connected during installation.

The V8DV2 uses a hybrid carbon fiber and polypropylene diaphragm with a stitch-reinforced Santoprene surround. This combination is designed to support controlled cone movement while handling demanding bass passages. Cerwin-Vega rates sensitivity at 85 dB (1W/1m), with a 52 Hz free-air resonance specification.

A ferrite motor structure and 2.5-inch voice coil form the core of the driver assembly. The subwoofer uses a cast aluminum basket and a single-terminal impedance selector for a tidy connection point. Its dual 2-ohm coils can be wired to present either a 1-ohm parallel load or a 4-ohm series load.

The V8DV2 can be used in a custom sealed or ported enclosure, with Cerwin-Vega publishing a ported enclosure recommendation for this model. Confirm available mounting clearance before cutting, as the driver requires a 7.48-inch cutout and 5.43 inches of mounting depth. Pair it with an amplifier stable at the intended final impedance and configure gain, crossover, and subsonic filtering appropriately.

Key Features

• Dual 2-Ohm Voice Coils: Supports 1-ohm parallel or 4-ohm series wiring for amplifier matching.
• 800W RMS Handling: Provides a continuous-power target for selecting a compatible amplifier.
• Hybrid Carbon Fiber/Polypropylene Diaphragm: Combines lightweight response with cone rigidity for bass reproduction.
• Stitch-Reinforced Santoprene Surround: Supports cone travel and helps provide long-term surround durability.
• Ferrite Motor Structure: Supplies the magnetic drive system behind the woofer assembly.
• Single-Terminal Impedance Selector: Consolidates the connection area for the dual-voice-coil configuration.

Design & Installation

The V8DV2 is built around a cast aluminum basket, ferrite magnet system, 2.5-inch voice coil, hybrid carbon fiber/polypropylene diaphragm, and Santoprene surround. Its overall diameter is 8.72 inches, while the outer-edge diameter is 8.05 inches. These dimensions should be compared with the enclosure baffle, grille clearance, and surrounding trim before installation.

Use an enclosure with a 7.48-inch cutout and at least 5.43 inches of mounting depth. For the manufacturer-published ported recommendation, use 0.20 cubic foot net internal volume, the specified slot-port dimensions, and a subsonic filter set no lower than 30 Hz. Wire the coils in parallel only with an amplifier rated for a 1-ohm load; series wiring presents a 4-ohm load.
