The DS18 HOOLIGAN KO H-KO10 is an extreme-output, Korean-made Class-D monoblock amplifier engineered for bassheads and SPL competitors who demand massive power, durability, and control. Delivering a staggering 10000W RMS at 1 OHM, this amplifier is built to drive the most demanding subwoofer systems with authority and consistency.

Designed around a heavy-duty Korean half-bridge platform, the H-KO10 is built stronger and more robust than typical full-bridge designs, allowing it to handle extreme current loads while maintaining efficiency and reliability. Integrated monitoring features—including a digital voltmeter, clip indicator, and remote bass knob—give you real-time system feedback so you can push your setup hard without sacrificing control or safety.

With wide crossover adjustment, infrasonic filtering, strap-mode capability, and full protection circuitry, the HOOLIGAN KO H-KO10 is purpose-built for high-power daily systems, demo vehicles, and competition-level SPL builds.
