Description
The ARC Audio X2 2500.1 is a high-output monoblock Class-D amplifier developed specifically for subwoofer systems. It delivers 900 watts RMS into 4 ohms, 1,500 watts RMS into 2 ohms, and 2,500 watts RMS into 1 ohm, making it suitable for high-power single- or multi-subwoofer installations.
The amplifier uses a high-frequency switching power supply, balanced differential input stage, and dedicated low-frequency signal path to maintain stable output and low noise at high power. Its adjustable low-pass crossover, variable-frequency bass boost, and included remote level control provide the tuning functions required for sealed, ported, and custom subwoofer systems.
The Stage 2 chassis combines an extruded aluminum body with a brushed hairline finish and illuminated rotatable badge. Single-side connections, quick-disconnect speaker terminals, automatic signal and DC-detect turn-on, and stored protection fault codes support clean installation and easier system diagnostics.
