DS18 X4 Ultra-Compact 4-Channel Class-D Car Amplifier – 140W RMS x 4 @ 2-Ohm
The DS18 X4 is an ultra-compact 4-channel Class-D car audio amplifier designed to deliver incredibly robust, full-range power from an unbelievably small footprint. Measuring just over five and a half inches long, this micro amplifier is the perfect solution for audiophiles needing to power a complete multi-speaker system in vehicles with extremely tight spaces. Whether you are tucking it inside a motorcycle fairing, mounting it under a UTV seat, or hiding it behind a dashboard in a custom car audio build, the X4 provides the versatility and high-fidelity punch you need without sacrificing valuable space.
Despite its palm-sized design, the X4 is packed with reliable, highly efficient power. It pushes 70 watts RMS per channel at 4 ohms, an impressive 140 watts RMS per channel at 2 ohms, and can be bridged to produce 220 watts mono across two channels at 4 ohms. It features a stable four-layer traces PCB design with surface mount components for superior durability against heavy vibration and harsh road conditions. Built with robust multi-way protection circuitry and easily adjustable crossover filters, the X4 proves that massive, crystal-clear, 4-channel sound doesn't require a massive amplifier.
