Cerwin-Vega CVP12D4 12" Dual 4-Ohm Subwoofer

The Cerwin-Vega CVP12D4 is a 12-inch car audio subwoofer designed to add dedicated low-frequency output to an aftermarket sound system. Its dual 4-ohm voice-coil configuration gives installers flexible wiring options for matching compatible amplifiers. It is intended for vehicles using a properly designed subwoofer enclosure and external amplification.

This subwoofer is a practical choice for listeners who want stronger bass impact than factory full-range speakers can provide. Its 200-watt RMS power rating helps guide amplifier matching for sustained use. The dual-voice-coil layout can be wired for a 2-ohm or 8-ohm final load when using one subwoofer.

The CVP12D4 uses a light, rigid polypropylene cone and a structure-reinforcing dust cap to support controlled cone movement. Its treated foam surround is dual stitched at the cone connection and ribbed to help maintain its shape under high-output use. Together, these components support deep bass reproduction in a conventional car-audio subwoofer installation.

For thermal management, the design uses perimeter-vented voice coils to promote cooling during operation. A bumped backplate provides additional clearance for cone excursion, while the CAD-optimized stamped-steel basket provides a stable mounting structure. The result is a purpose-built driver with features focused on durability, cooling, and excursion control.

The CVP12D4 can be used in either sealed or ported enclosure systems, depending on the installation goals and enclosure design. A sealed enclosure is commonly selected for a more compact installation, while a ported enclosure can be used when designed for the driver and vehicle. Pair it with a compatible mono or bridged amplifier whose stable load capability matches the chosen voice-coil wiring.

Key Features

• 12-Inch Subwoofer: Adds dedicated low-frequency capability to a car audio system.
• Dual 4-Ohm Voice Coils: Supports 2-ohm or 8-ohm wiring configurations.
• 200W RMS Power Handling: Helps match the subwoofer with an appropriately rated amplifier.
• Polypropylene Cone: Provides a light, rigid diaphragm for bass reproduction.
• Perimeter Voice-Coil Venting: Promotes cooling for sustained operation.
• Bumped Backplate: Provides clearance for increased cone excursion.

Design & Installation

The CVP12D4 is built around a stamped-steel basket, ferrite magnet structure, polypropylene cone, and treated foam surround. A dual-stitched, ribbed surround, reinforced dust cap, vented voice-coil arrangement, and bumped backplate are incorporated into the driver design. Large-gauge spring terminals simplify connection of suitable speaker wire.

Confirm the enclosure opening, mounting depth, and available clearance before installation; the listed cutout diameter is 301 mm and mounting depth is 151 mm. Wire both voice coils correctly and ensure the amplifier is stable at the final 2-ohm or 8-ohm load. The subwoofer, enclosure, amplifier, wiring, and installation hardware should be selected separately as needed for the vehicle.
