Delivers 2 x 750 watts RMS at 4 ohms, 4 x 430 watts RMS at 2 ohms and 4 x 275 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 86%. 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/FULL/LPF crossover covering 40Hz-2KHz and bass boost adjustable from No centered between No. Send each channel only the frequencies it should play and dial in the low end without adding an external processor.
Built with over-load, dc output, short circuit output and clipping 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 SXE-4000.4D/BK is a 4-channel car amplifier from the DS18 SXE series, built as a Class D design. It delivers 2 x 750 watts RMS at 4 ohms, 4 x 430 watts RMS at 2 ohms and 4 x 275 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 0.05% with a signal-to-noise ratio of 90dB. A selectable HPF/FULL/LPF crossover covers 40Hz-2KHz, so you can send each channel only the frequencies it should reproduce. Bass boost is adjustable from No centered between No. Match the amplifier to the RMS rating of your speakers or subwoofers and set the gain to that rating for clean, reliable output.
