DS18’s H-KO340 is a high quality, high performance, and HIGH POWERED 4-Channel Full-Range Class D Competition Amplifier. This Korean-made powerhouse is built to be beefier, more efficient, and even more durable for competition-level performance.

DS18’s H-KO340 is designed to deliver MASSIVE POWER: with RMS ratings of 4 x 300W at 4 ohms, 4 x 550W at 2 ohms, and 2 x 1000W at 4 ohms bridged. This amplifier is so powerful, we’ve equipped it with a range of protection circuits including thermal, over-load, DC, short circuit, voltage, and clipping. The LED indicators provide a clear visual representation of the amplifier's working status, protecting you and your vehicle from damage.
