Cerwin Vega CVP1400.4 4-Channel Class D Car Amplifier

The Cerwin Vega CVP1400.4 is a compact four-channel Class D car amplifier designed to add dedicated power to a factory or aftermarket audio system. It is suited to powering front and rear speakers, component sets, or two bridged speaker channels where a system calls for higher output. Its small chassis helps address installations where conventional amplifiers may be difficult to place.

Rated for 80 watts RMS per channel at 4 ohms and 140 watts RMS per channel at 2 ohms, the CVP1400.4 provides a practical power range for many car-audio speakers. It can also be bridged to deliver 290 watts RMS to each of two 4-ohm loads. This flexibility allows the amplifier to serve as a four-speaker amplifier or as part of a more focused two-channel system.

Class D operation supports efficient power delivery in a compact enclosure. The amplifier uses a full MOSFET DC-DC PWM power supply, a double-sided two-layer circuit board, and surface-mount-device technology. Its frequency response extends from 10 Hz to 30 kHz, supporting full-range speaker applications.

Integration is supported through both low-level and high-level input capability. The high-level input includes auto turn-on operation for compatible 4V to 8V speaker-level signals, helping the amplifier work with many factory radios without requiring a separate line-output converter. Variable high-pass and low-pass filters allow each channel pair to be configured for the connected speakers.

The CVP1400.4 is a useful upgrade path for listeners who want more headroom and control than a radio's built-in amplifier can provide. It supports 2-ohm stereo loads and 4-ohm bridged loads, so speaker selection and wiring should be planned around those minimum impedances. Built-in protection provisions help safeguard the amplifier against short-circuit, low-impedance, reverse-polarity, and overheating conditions.

Key Features

• Four-Channel Class D Design: Powers up to four speakers from a compact amplifier chassis.
• 80W x 4 RMS at 4 Ohms: Provides dedicated full-range power for compatible speakers.
• 2-Ohm Stable Stereo Operation: Delivers up to 140W RMS per channel at 2 ohms.
• Bridgeable Channel Pairs: Supports 290W RMS x 2 into 4-ohm bridged loads.
• High-Level Inputs with Auto Turn-On: Helps integrate the amplifier with compatible factory radio outputs.
• Variable HPF and LPF: Lets you tailor frequency range to the speakers being used.

Design & Installation

The CVP1400.4 uses a compact 7.28-inch by 4.92-inch by 1.93-inch chassis. Its construction includes a full MOSFET DC-DC PWM power supply, double-sided two-layer PCB, and SMD technology. Power and protection indicators provide operating-status feedback, while the protection system addresses short circuit, low impedance, reverse polarity, and overheating conditions.

Mount the amplifier on a solid surface with adequate ventilation and access to the side-panel controls. Use 2-ohm-or-higher stereo speaker loads or 4-ohm-or-higher bridged loads, and configure the high-pass or low-pass filters to suit the speakers. The manual specifies a negative-ground 12V DC vehicle electrical system, recommends a minimum of 8 AWG power and ground wiring, and states that the terminals accept up to 4 AWG cable.
