Delivers 4 x 200 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 83%. That means less strain on your electrical system and a smaller chassis for the same power.
IP67 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 Yes (HPF/Full/LPF) crossover covering 40Hz-2KHz and bass boost adjustable from N/A 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 over-load, short circuit output and uv / salt fog 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.
The NXL-X850.4D is a 4-channel car amplifier from the DS18 NXL-X series, built as a Class D design. It delivers 4 x 200 watts RMS at 4 ohms. Total harmonic distortion is rated at less than 0.04% with a signal-to-noise ratio of greater than 83dB. A selectable Yes (HPF/Full/LPF) crossover covers 40Hz-2KHz, so you can send each channel only the frequencies it should reproduce. Bass boost is adjustable from N/A centered between N/A. A IP67 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.
