Crunch CRA-1500.4 CRA Series 1500 Watt Four Channel Amplifier 185x4 @ 4OHM, 375x4 @ 2OHM, 750x2 @ 4OHM Bridged

The Crunch CRA-1500.4 is a versatile 4-channel Class D amplifier designed to deliver strong, efficient output within a compact footprint. It features a Switch Mode Power Supply (SMPS) that ensures stable and reliable power output, regardless of battery voltage. This design helps prevent performance drops and protects connected components from voltage fluctuations. With a maximum output of 1500 watts, this amplifier supports a wide range of system configurations, making it suitable for various speaker and subwoofer setups.

This amplifier produces 4 x 185 watts at 4 ohms and 4 x 375 watts at 2 ohms. It can also be bridged to deliver 2 x 750 watts at 4 ohms, offering flexible operation modes including four-channel stereo, dual bridged, and mixed stereo/bridged setups. Audio performance is enhanced by a low-noise preamplifier circuit and proprietary SPEED-FET MOSFET output devices, which work to reduce distortion and improve efficiency.

The CRA-1500.4 includes fully adjustable 12dB per octave crossovers with both high-pass and low-pass filters, tunable from 40Hz to 400Hz for precise system tuning. Installation is simplified with both RCA and high-level inputs, alongside an auto turn-on function for seamless OEM integration. Nickel-plated brass connection terminals and screw-down connectors ensure secure, corrosion-resistant connections, while built-in LED protection diagnostics monitor for overload and speaker short faults, ensuring reliable long-term operation.
