Our take on the DS18 ZXI.4 ELITE Full-Range 4-Channel Class D Amplifier

The DS18 ZXI.4 ELITE is a compact four-channel Class D full-range amplifier rated at 125W RMS per channel at 4 ohms, with a 2200W peak figure. It is bridgeable, has a built-in crossover, a pair of preamp outputs and a signal-to-noise ratio above 90dB with distortion under 0.1%. Its small footprint and low heat output suit tight installs where a full-size Class AB amp will not fit. Against rival compact four-channels it trades big-name tuning support for a simple, low-cost full-range design.

Questions and answers

How much power does it really make?
DS18 rates it at 125W RMS per channel at 4 ohms across four channels. The 2200W figure is peak, not continuous, so plan your speakers around the RMS rating.
Can I bridge it to run a subwoofer?
Yes, it is bridgeable. Bridging pairs of channels gives you two higher-power outputs, enough for a modest subwoofer or a pair of component woofers.
Does it have a built-in crossover?
Yes. A built-in crossover lets you filter low or high frequencies per channel pair, which helps when you split duties between speakers and a sub.
Will it fit in a small space?
The chassis is about 5.66 inches wide and 1.9 inches tall, so it fits under a seat or in a side panel. Class D operation keeps heat lower than a Class AB amp of similar size.
Can I add another amplifier later?
Yes. It has one pair of preamp outputs, so you can feed a signal to a second amp, such as a dedicated subwoofer amplifier.
Does it need a heavy power wire?
Class D amps are more efficient, but four channels still draw real current. Follow DS18's fuse and wire gauge recommendation for the total RMS output.
