The Boss Audio Elite BE400.1D is a compact monoblock Class D amplifier designed to deliver powerful, clean bass without taking up much space. It produces 130W RMS at 4 ohms, 280W RMS at 2 ohms, and up to 400W RMS at 1 ohm, with a low 0.01% THD for clear performance.

Measuring just 7.79" x 4.56" x 1.71", it fits easily into tight installations and features LED-illuminated end panels. Sound can be customized with a 50Hz–250Hz low-pass filter, 15Hz–40Hz infrasonic filter, 0dB to +12dB bass boost, and remote subwoofer level control. RCA and speaker-level inputs provide flexible connectivity, while thermal, short, and overload protection help keep the amplifier and connected equipment safe during demanding use.
