Cerwin-Vega CVP2400.1 Mono Class-D Car Amplifier

The Cerwin-Vega CVP2400.1 is a compact mono Class-D car amplifier designed to power a dedicated subwoofer system. It provides a focused low-frequency amplification solution for vehicles where factory bass output is limited or an aftermarket subwoofer upgrade is planned. Its small chassis helps accommodate installations where available space is restricted.

Designed for bass applications, the CVP2400.1 delivers 370 watts RMS at 4 ohms, 660 watts RMS at 2 ohms, and 900 watts RMS at 1 ohm. The mono configuration concentrates its output into one subwoofer channel rather than powering a set of full-range speakers. This makes it suitable for matching with a properly wired subwoofer or subwoofer system that supports its impedance capability.

The amplifier uses a Class-D design with a full MOSFET DC-DC PWM power supply. Its frequency response is specified from 10 Hz to 400 Hz, covering the low-frequency range commonly used in vehicle subwoofer systems. Adjustable subsonic and low-pass filtering helps tailor the amplifier's output to the enclosure, subwoofer, and listening preferences.

For integration flexibility, the CVP2400.1 includes RCA inputs and high-level inputs with automatic turn-on capability. This allows it to work with many aftermarket head units as well as factory audio systems that provide speaker-level signals. Input sensitivity is adjustable from 250 mV to 6 V for matching the source signal level.

A supplied subwoofer level remote control gives the driver a convenient way to attenuate the established bass level from the cabin. Protection circuitry addresses short-circuit, low-impedance, reverse-polarity, and overheating conditions. The result is a compact amplifier intended for a practical subwoofer upgrade in cars, trucks, and SUVs.

Key Features

• Mono Class-D Design: Focuses amplifier output on a dedicated subwoofer channel.
• 1-Ohm Stable Output: Supports properly wired mono loads from 1 to 8 ohms.
• Compact Chassis: Fits more easily in limited under-seat or trunk space.
• High-Level Inputs: Helps integrate with compatible factory speaker-level audio signals.
• Adjustable Filters: Provides subsonic and low-pass frequency control for bass tuning.
• Remote Bass Level Control: Lets the driver adjust the established subwoofer level from the cabin.

Design & Installation

The CVP2400.1 uses a small 8.86-inch-long chassis with a double-sided, two-layer circuit board and surface-mount-device construction. Its Class-D platform and MOSFET DC-DC PWM power supply are engineered for compact vehicle-audio amplification. Power and protection status indication is provided on the amplifier.

Install the amplifier on a solid, ventilated surface with the controls accessible after mounting; avoid covering it with carpet or wiring. Use properly sized power, ground, remote-turn-on, signal, and speaker wiring, with an inline fuse near the vehicle battery as directed by the installation manual. A 4-ohm, 2-ohm, or 1-ohm subwoofer load should be selected only when its final wired impedance and power handling are appropriate for the corresponding amplifier rating.
