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.

The Tiffany RCA connectors ensure a secure and reliable connection for optimal audio performance. Strap mode connection and included remote bass knob offers convenient control over your audio system. You can easily adjust the bass levels on-the-fly, allowing you to fine-tune your sound to perfection. The selectable X-Over allows for HPF, LPF, and band-pass filtering, ensuring precise sound shaping and FULL RANGE CONTROL.
