The NXL-M4 is a 4-channel car amplifier from the DS18 NXL-M series, built as a Class D design. It delivers 4 x 150 watts RMS at 4 ohms. Total harmonic distortion is rated at less than 0.15% with a signal-to-noise ratio of greater than 90dB. A selectable HPF/LPF/FULL crossover covers 40Hz - 2KHz, so you can send each channel only the frequencies it should reproduce. Bass boost is adjustable from 0-12dB centered between 45Hz +- 5Hz. A IP55 waterproof rating makes it suitable for boats, side-by-sides and powersports vehicles where the amplifier is exposed to water and spray. Match the amplifier to the RMS rating of your speakers or subwoofers and set the gain to that rating for clean, reliable output.
Delivers 4 x 150 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 greater than 97%. That means less strain on your electrical system and a smaller chassis for the same power.
IP55 waterproof rating protects the amplifier from water, spray and humidity, so it holds up on boats, UTVs, side-by-sides and motorcycles where the amp is exposed. Mount it where a standard car amplifier would not survive.
Onboard tuning includes a selectable HPF/LPF/FULL crossover covering 40Hz - 2KHz and bass boost adjustable from 0-12dB centered between 45Hz +- 5Hz. 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, short circuit output and voltage input 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.
