Crunch CM2

The Crunch CM2 is an exceptionally compact and powerful 2-channel Class D amplifier that delivers impressive output power despite its small size. With up to 2 x 175 watts RMS at 2 ohms or 350 watts RMS in bridge mode at 4 ohms, this mini power amplifier is ideal for high-power speaker systems or driving a subwoofer.

Thanks to modern Class D technology, the CM2 achieves an efficiency of up to 85% and combines high power output with a compact design. Measuring just 90 x 43 x 140 mm, the amplifier can be easily mounted under the dashboard, behind trim panels, or in other tight installation spaces. The high-quality die-cast aluminum heat sink with the Diamond-Cut logo provides an attractive appearance and aids in heat dissipation.

Adjustable high-pass and low-pass filters ranging from 50 to 5,000 Hz are available for flexible sound tuning. In addition to standard RCA inputs, the CM2 features high-level inputs with EPS technology, allowing the amplifier to be integrated into numerous factory-installed sound systems. An automatic power-on function via DC offset or audio signal detection further simplifies retrofitting. Additional amplifiers can be connected via the built-in RCA outputs.

Removable power and speaker connectors simplify installation and make the Crunch CM2 a versatile solution for space-saving car audio upgrades.
