The DS18 SXE-3000.4D is a compact 4-channel Class D full-range car amplifier rated 200W x 4 at 4 ohms, 320W x 4 at 2 ohms, and 500W x 2 bridged. It is under 10 inches long and 1.8 inches tall, so it fits under a seat or in tight spaces where full-size amps will not. Selectable HPF, full-range and LPF crossovers let it drive door speakers, a sub, or both from one chassis. It suits budget-minded builds that want Class D efficiency and small footprint, though it is a value-brand amp rather than a premium SQ piece.

Owner feedback on the SXE line is mixed. People like the small size and the power for the money, but some report failures and noise after a season of use.
The DS18 SXE-3000.4D is a full-range 4-channel Class D amplifier. It is rated at 200W x 4 at 4 ohms, 320W x 4 at 2 ohms, or 500W x 2 bridged at 4 ohms. The peak power rating is 3000W.
It is just under 10 inches long and 1.8 inches tall, so it can fit in compact installations such as under a seat. A selectable HPF/FULL/LPF crossover, adjustable crossovers and gain controls let it run door speakers, a subwoofer, or both.
Built-in protection covers thermal shutdown, overload, short circuit, voltage fluctuation and clipping. LED indicators show power, protect and clip status. The finish is black brushed aluminum, and the amplifier is sold individually.
