The H-KO340/RD is a 4-channel car amplifier from the DS18 HOOLIGAN KO series, built as a Class D design. It delivers 2 x 1000 watts RMS at 4 ohms, 4 x 550 watts RMS at 2 ohms and 4 x 300 watts RMS at 4 ohms. The channels are bridgeable, so you can combine them to drive a subwoofer or a pair of higher-power speakers from the same amplifier. Total harmonic distortion is rated at less than 0.2% with a signal-to-noise ratio of greater than 90dB. A selectable HPF/LPF/BAND-PASS crossover covers HPF: 20Hz-8KHz / LPF: 50Hz-8KHz (1X/10X), so you can send each channel only the frequencies it should reproduce. Bass boost is adjustable from No centered between N/A. Match the amplifier to the RMS rating of your speakers or subwoofers and set the gain to that rating for clean, reliable output.

Delivers 2 x 1000 watts RMS at 4 ohms, 4 x 550 watts RMS at 2 ohms and 4 x 300 watts RMS at 4 ohms. Power scales as impedance drops, so check the rating at the impedance you plan to run before matching speakers.
A Class D topology runs cooler and draws less current than a conventional amplifier at the same output, with rated efficiency of 90%. That means less strain on your electrical system and a smaller chassis for the same power.
Bridge the channels to combine their output and drive a subwoofer or a pair of higher-power speakers from the same amplifier, which lets one amp cover both your speakers and your bass instead of buying two.
Onboard tuning includes a selectable HPF/LPF/BAND-PASS crossover covering HPF: 20Hz-8KHz / LPF: 50Hz-8KHz (1X/10X) and bass boost adjustable from No centered between N/A. Send each channel only the frequencies it should play and dial in the low end without adding an external processor.
Built with thermal, over-load, dc output and short circuit output protection, so the amplifier shuts itself down before a wiring fault, a short or overheating can damage it or your speakers. That is what keeps 4-channel amplifiers alive in daily-driven vehicles.
