Description
The ARC Audio X2 1100.1 is a high-performance monoblock Class-D amplifier designed for subwoofer and midbass applications. Its frequency-limited output range directs the amplifier's power to low-frequency drivers rather than full-range speakers, supporting daily-driver systems, custom bass installations, and higher-output builds.
The X2 1100.1 produces 350 watts RMS into 4 ohms, 600 watts RMS into 2 ohms, and up to 1,100 watts RMS into 1 ohm. A dedicated master/slave strapping circuit allows two amplifiers to operate together with synchronized signal control and up to 2,200 watts of combined output for systems requiring greater low-frequency power.
Advanced power-supply filtering, Infineon output devices, and balanced differential inputs support efficient operation and integration with either aftermarket or factory source units. The Level 2 cosmetic package includes a brushed silver hairline aluminum top panel, an illuminated rotatable acrylic badge, and front diagnostic indicators.
