The DS18 SMD-2800.5 is a 5-channel car amplifier. It combines four analog Class AB full-range channels with a digital subwoofer channel. The subwoofer channel delivers 1800W at 1 ohm, and the full-range channels deliver 250W x 4 at 2 ohms.
It has HPF, LPF and Full crossover modes, a 50Hz-2KHz crossover range and a 0-9dB bass boost. Protection covers thermal, overload, DC output, short circuit, input voltage and clipping faults, and a built-in fan cools the unit. The board is a heavy-duty Korean design, with 0 AWG power input terminals and Tiffany RCA connectors.
A front acrylic window shows digital RGB lighting. An IR remote controls the LED colors and patterns. A remote level knob with a clip indicator in a metal case is included.
