Description
Overview
The Crunch CRA-3000.1 is a high-power mono Class D amplifier designed for mobile audio systems requiring strong, efficient bass performance. Featuring switch mode power supply (SMPS) technology, it delivers stable output regardless of vehicle voltage conditions while maintaining efficiency and thermal control.
Key Features
- High-efficiency Class D mono amplifier design
- Switch Mode Power Supply (SMPS) for stable voltage regulation
- RCA and high-level inputs for OEM or aftermarket integration
- DC signal sense auto turn-on functionality
- Built-in electronic crossover with 12dB/octave slope
- Wired bass remote included for in-vehicle bass level control
Engineering & Performance
The CRA-3000.1 utilizes proprietary SPEED-FET MOSFET output technology and a low-noise preamplifier circuit to minimize distortion while maximizing power delivery. Its aluminum heat sink is engineered for rapid thermal dispersion, helping maintain consistent performance under heavy load conditions.
With a signal-to-noise ratio of -79.9 dBA and total harmonic distortion under 1%, the amplifier is designed to maintain clean bass output even at high output levels.
Integration & Controls
Flexible installation options include RCA inputs and high-level inputs for factory systems without RCA outputs. The DC signal sense feature allows automatic turn-on without a dedicated remote wire when enabled. A fully adjustable crossover and bass boost control allow precise tuning of low-frequency response.
