Cerwin-Vega CVPRO2K4 4-Channel Class D Car Amplifier

The Cerwin-Vega CVPRO2K4 is a four-channel Class D car audio amplifier for systems that need substantial power in a compact chassis. It can run front and rear speakers from four channels or be bridged for higher-power two-channel applications. Its 2-ohm-stable channel design provides flexibility when matching the amplifier to compatible speaker loads.

This amplifier is suited to enthusiasts building a high-output speaker system, upgrading component speakers, or designing a custom multi-amplifier installation. It supplies 325 watts RMS per channel at 4 ohms or 520 watts RMS per channel at 2 ohms. For bridged configurations, it is rated at 1,000 watts RMS per pair of channels into 4 ohms.

The CVPRO2K4 uses a full-range Class D topology and a full PWM power supply. Its specified bandwidth extends from 15 Hz to 20 kHz, allowing it to support bass, midrange, and high-frequency drivers when the system is configured appropriately. A damping factor greater than 150 and a specified THD figure of 0.1% at 1 kHz and 4 ohms support controlled signal delivery.

System tuning is handled with selectable high-pass, flat, and low-pass crossover modes. The crossover network uses a 12 dB-per-octave slope, with variable high-pass, low-pass, and subsonic-filter adjustments. Variable bass boost is also provided for users who need to tailor low-frequency response carefully.

Designed for vehicle installation, the CVPRO2K4 has a compact 10.4 by 8.8 by 2.6 inch footprint. RCA preamp inputs connect the amplifier to a compatible source unit, while power, ground, remote-turn-on, and speaker terminals support a conventional amplified car-audio installation. Power/protection and clipping indicators provide at-a-glance operating status.

Key Features

• Four-Channel Class D Design: Powers a full speaker system from a compact, efficient amplifier platform.
• 2-Ohm Stable Channels: Supports compatible 2-ohm speaker loads on each unbridged channel.
• Bridgeable Output: Combines channel pairs for higher-power 4-ohm speaker applications.
• Adjustable Crossovers: Helps match output frequencies to speakers, subs, or pro-audio drivers.
• Variable Bass Boost: Provides adjustable low-frequency boost from 0 to 12 dB.
• Status And Clip LEDs: Shows power, protection, and clipping status during operation.

Design & Installation

The CVPRO2K4 uses a rugged, ventilated amplifier chassis with a compact footprint intended for custom vehicle audio installations. Its full PWM power supply, high-current design, and protection-status indication are intended for demanding amplified systems. The amplifier measures 10.4 by 8.8 by 2.6 inches, so it can fit where larger multi-channel amplifiers may be difficult to mount.

Mount the amplifier on a solid surface with ventilation around the chassis and keep its control panel accessible for adjustment. Use a negative-ground 12-volt vehicle electrical system, route RCA signal cables away from power wiring where practical, and use properly fused power wiring. Cerwin-Vega recommends 0/1-gauge OFC power and ground wire, and the amplifier is designed for a 150-amp fuse rating.
