Description
Overview
The Crunch CRA-2000.1 is a mono Class D amplifier designed for high-output subwoofer applications. It combines efficient power delivery with flexible installation options and built-in signal processing controls for system tuning.
Key Features
- Class D mono amplifier design for efficient high-power output
- Switch Mode Power Supply (SMPS) for stable voltage-independent performance
- Fully adjustable 12dB/octave electronic crossover network
- RCA and high-level inputs for OEM and aftermarket system integration
- DC signal sense auto turn-on capability for simplified installation
- Wired bass remote included for real-time bass level control
Engineering & Performance
Built on a high-efficiency Class D topology, the CRA-2000.1 uses proprietary SPEED-FET MOSFET technology and a switch mode power supply to maintain output stability and minimize distortion. Thermal management is supported by a heavy-duty aluminum heat sink designed for rapid heat dispersion during extended use.
Connectivity & Installation
The amplifier supports both RCA and high-level inputs, allowing integration with aftermarket head units or factory OEM systems. Nickel-plated brass terminals and screw-down connectors ensure secure, corrosion-resistant wiring connections. DC signal sense auto turn-on eliminates the need for a remote turn-on wire in many installations.
