Crunch CRA-1500.1 CRA Series 1500 Watt Mono Block Amplifier

The Crunch CRA-1500.1 CRA Series Monoblock Class D Amplifier is engineered to deliver strong, efficient bass performance in a compact and versatile design. Built on a Class D platform, it provides high output power while maintaining efficiency, making it ideal for subwoofer applications in a wide range of mobile audio systems. It features proprietary Crunch SPEED-FET MOSFET components that maximize power efficiency, improve sound quality, and minimize distortion.

With up to 1500 watts of maximum output at 1 ohm, this amplifier is designed to drive subwoofers with authority, delivering 750 watts at 2 ohms and 375 watts at 4 ohms. It offers flexible impedance matching for various system configurations. Precision tuning controls include a variable low-pass crossover (40Hz–300Hz) with a 12dB/octave slope and a built-in subsonic filter (10Hz–40Hz) to eliminate unwanted ultra-low frequencies, protecting your subwoofer and improving overall efficiency.

The amplifier also features a built-in bass boost (0–12dB) and an included wired bass remote for convenient, real-time adjustment of low-frequency output. For flexible installation, it supports both RCA and high-level inputs and includes a DC signal sense auto turn-on feature, eliminating the need for a remote turn-on wire. Durable nickel-plated brass terminals and screw-down connectors ensure secure, corrosion-resistant connections for power and speaker wiring.
