Crunch - CRA-2000.4 CRA Series 2000 Watt Four Channel Amplifier 250x4 @ 4OHM, 500x4 @ 2OHM, 1000x2 @ 4OHM Bridged - Black/Gray

By the beard of Zeus! Now even mere mortals can harness divine amplification power straight from the lofty, cloud crowned heights of Mount Olympus when wielding the Hifonics Zeus ZXX 2400.1D 2400 Watt Class D Monoblock Amplifier.This high efficiency class D amp has Herculean power in a small footprint. Its PWM MOSFET power supply strikes like lightning, but without extra noise or distortion thanks to its low noise pre amplifier circuitry. The Simpatico dual coil design power supply keeps voltage constant. Meanwhile, use the included remote to crank that bass like the magnificent sound deity you are.With a frequency response of 10Hz 300Hz, variable electronic crossovers, and 2400 watts of max power, the Zeus ZXX 2400.1D will take your car audio to new mythological heights.

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.
