Compact Powerhouse for Versatile High-Performance Audio

The DS18 FRP-1.2K4 is a high-efficiency Class D full-range multi-channel amplifier designed to deliver massive power from a compact, installation-friendly chassis. This versatile 4-channel powerhouse produces 120W RMS per channel at 4 ohms and is stable down to 1 ohm, where it delivers a staggering 4 x 300W. Precision-engineered with a four-layer PCB design and high-quality Tiffany RCA terminals, the amplifier features a comprehensive suite of protections—including thermal, overload, and short-circuit safeguards—alongside a smart cooling fan for sustained performance. With a wide frequency response of 10Hz to 200kHz and integrated selectable crossovers (HPF/FULL/LPF), this amplifier provides the clean, distortion-free output and flexible tuning options necessary to drive complex car audio builds with absolute authority.
