The Crunch CRA-1500.4 is a versatile 4-channel Class D amplifier built to deliver strong, efficient output while maintaining a compact footprint. Designed with a switch mode power supply (SMPS), it provides stable and reliable power regardless of battery voltage, helping prevent performance drops and protecting connected components from voltage fluctuations. With a maximum output of 1500 watts, this amplifier supports a wide range of system configurations. It produces 4 x 375 watts at 2 ohms and 4 x 185 watts at 4 ohms, and can be bridged to deliver 2 x 750 watts at 4 ohms. Multiple operation modes—including four-channel stereo, dual bridged, and mixed stereo/bridged setups—allow flexible system design for speakers and subwoofers. Audio performance is supported by a low-noise preamplifier circuit and SPEED-FET MOSFET output devices, helping reduce distortion while improving efficiency. The amplifier offers a frequency response of 10Hz to 30kHz and features adjustable 12dB per octave crossovers, with both high-pass and low-pass filters ranging from 40Hz to 400Hz for precise system tuning. Installation is straightforward with both RCA and high-level inputs, including auto turn-on capability for OEM integration. Nickel-plated terminals and screw-down connectors ensure secure, corrosion-resistant connections, while built-in LED protection diagnostics monitor overload and speaker faults for reliable long-term operation.
