About this product
The Crunch CRA-2000.1 is a high-efficiency monoblock Class D amplifier designed to deliver strong, reliable bass performance for mobile audio subwoofer systems. Rated at up to 2000 watts max output at 1 ohm, it is built to maintain stable power delivery through a Switch Mode Power Supply (SMPS), helping ensure consistent performance even as vehicle voltage conditions fluctuate. This makes it well-suited for demanding bass applications where output stability is critical. Engineered with Class D efficiency and Crunch SPEED-FET MOSFET output technology, the CRA-2000.1 is designed to maximize power while minimizing distortion and heat buildup. A low-noise preamplifier circuit helps preserve signal clarity from the source unit, while integrated electronic crossover controls allow precise system tuning. With both RCA and high-level inputs, the amplifier easily integrates into aftermarket audio systems or factory OEM setups without requiring extensive modification. For tuning flexibility, the amplifier includes a fully adjustable 12dB/octave low-pass crossover ranging from 40Hz to 300Hz, a subsonic filter (10Hz–40Hz), and a variable bass boost from 0–12dB. A wired bass remote is included, allowing real-time bass level adjustments from the driver’s seat. DC signal sense auto turn-on functionality simplifies installation by automatically powering the amplifier when signal is detected, reducing the need for a dedicated remote wire in many builds.
