Cerwin-Vega CVP2400.4 4-Channel Class D Amplifier

The Cerwin-Vega CVP2400.4 is a compact four-channel Class D car amplifier for adding dedicated power to an aftermarket or factory audio system. It is designed for drivers who want to run front and rear speakers, a component speaker system, or a bridged two-channel configuration from one small amplifier. Its compact chassis helps solve mounting-space limitations in cars, trucks, and SUVs.

At 4 ohms, the CVP2400.4 is rated for 120 watts RMS per channel, while its 2-ohm rating reaches 210 watts RMS per channel. This gives it the capacity to support speakers that need more power and control than a typical radio’s built-in amplifier can provide. When correctly set up, it can bring greater output capability and system headroom to a vehicle audio upgrade.

The amplifier uses a Class D design with a full MOSFET DC-DC PWM power supply. Its 10 Hz to 30 kHz frequency response supports full-range speaker applications, and adjustable high-pass and low-pass filters help tailor the signal for the speakers being used. The four-channel layout can also be bridged to provide 410 watts RMS to each of two 4-ohm loads.

High-level inputs with automatic turn-on support integration with many factory radios, while low-level signal sensitivity supports aftermarket source units. This flexibility can simplify upgrades where replacing the existing radio is not preferred. A power/protection indicator provides a visible operating-status reference.

The CVP2400.4 is part of Cerwin-Vega's CVP Series and measures less than nine inches long. It is suited to powering door speakers, component systems, or selected bridged speaker and subwoofer applications within its rated impedance limits. Built-in protection features are intended to help safeguard the amplifier during short-circuit, low-impedance, reverse-polarity, and overheating conditions.

Key Features

• Four-Channel Class D Design: Powers up to four speakers from one compact amplifier.
• 120W x 4 RMS at 4 Ohms: Provides dedicated power for compatible full-range speakers.
• 2-Ohm Stable Operation: Delivers up to 210W RMS per channel at 2 ohms.
• Bridgeable Channels: Supports 410W RMS x 2 at 4 ohms.
• High-Level Inputs: Helps integrate the amplifier with compatible factory radios.
• Adjustable Crossovers: Lets you set high-pass or low-pass filtering for the system.

Design & Installation

The CVP2400.4 uses a small chassis measuring 8.86 by 4.92 by 1.93 inches. Its construction includes a full MOSFET DC-DC PWM power supply, double-sided two-layer circuit board, and surface-mount-device technology. Protection circuitry covers short circuits, low impedance, reverse polarity, and overheating.

Mount the amplifier securely in a dry location with ventilation and access to its side-panel controls. It requires a negative-ground 12V DC vehicle electrical system; use appropriate fused power wiring, with the manufacturer documentation recommending a 4 AWG amplifier wiring kit. Maintain at least 2 ohms per channel in stereo operation or 4 ohms when bridged, and set crossover and gain controls to match the connected speakers.
