The Crunch CRA-950.4 is a versatile 4-channel Class D amplifier designed for flexible system builds, delivering efficient and stable power for full-range speakers or bridged subwoofer configurations. With a 950W max output and a high-efficiency switch mode power supply (SMPS), it maintains consistent performance even as vehicle voltage fluctuates. Built for installation flexibility, it supports both RCA and high-level inputs, making it compatible with aftermarket head units and factory OEM systems. DC signal sense auto turn-on simplifies wiring in many installations by eliminating the need for a dedicated remote wire. Fine-tuning is easy with fully adjustable 12dB/octave high-pass and low-pass crossovers ranging from 40Hz to 400Hz. Multiple operating modes—including stereo, bridged, and mixed configurations—allow custom system design for speakers, tweeters, or subwoofer setups. Engineered with Class D efficiency and Crunch SPEED-FET MOSFET output technology, the CRA-950.4 delivers clean sound with low distortion while minimizing heat buildup. A reinforced aluminum heat sink and thermal dispersion design ensure reliable performance under load, while built-in protection circuitry helps safeguard the system.
