Arc Audio X2 1100.1 - 1100 Watt Mono Subwoofer Amplifier
The ARC Audio X2 1100.1 is a high-performance mono amplifier designed exclusively for subwoofer and midbass applications. Featuring a frequency-limited output range of 10Hz to 230Hz, it's built for clean, controlled low-frequency power — not full-range operation.
Delivering up to 1100 watts at 1 ohm, the X2 1100.1 provides serious output for single or multi-sub systems. For high-output builds, it features a dedicated master/slave strapping circuit, allowing two amplifiers to operate in unison with synchronized signal control and up to 2200 watts of combined output into a single subwoofer load.
As part of ARC’s Level 2 X2 lineup, it includes the premium cosmetic package — brushed silver hairline top panel, illuminated rotatable badge, and front-mounted diagnostic indicators — along with advanced power supply filtering and Infineon output devices for improved thermal efficiency and sonic detail.
Balanced differential inputs ensure seamless OEM or aftermarket integration, making the X2 1100.1 ideal for stealth upgrades, full custom systems, or competition-grade low-frequency builds where clean output and control are critical.
