The Vibe BLACKDEATHM21K-V6 is a competition monoblock amplifier using Ultra Class D topology for high efficiency and extreme power density. It uses a unique FET combination for improved heat dissipation, dual internal cooling fans for extended runtime under heavy load, and carries full EMI and CE approval. Efficiency reaches up to 92% and the design reduces footprint by about 50 percent compared to conventional Class D amplifiers.

Designed for high-current car audio systems, the amp supports full range and subwoofer use with a 5Hz to 20kHz frequency response, LP and HP crossover options (10Hz to 15kHz), input sensitivity of 200mV to 8V, and operating voltage range of 9v DC – 15v DC. Power ratings include 3470W RMS at 4 ohms, 7200W RMS at 2 ohms, 10500W RMS at 1 ohm, and a maximum power figure of 21000W. Recommended fuse rating is 1000A (4x0awg).
