The ARC Audio X2 1100.5 is designed to power your entire audio system — speakers and subwoofer — from a single amplifier chassis. Built on the same advanced platform as the X2 600.4, the 1100.5 combines the precision, power, and tuning flexibility of its 4-channel sibling with a dedicated, frequency-limited subwoofer channel for true all-in-one performance.

Channels 1 through 4 deliver 150 watts each at both 2 and 4 ohms, using the same impedance-switching technology found in the rest of the X2 Level 2 line. Channel 5 provides up to 500 watts at 2 ohms and is optimized specifically for subwoofer duty, delivering powerful, clean bass that integrates seamlessly into your system.

Channels 3 and 4 include adjustable bandpass crossovers, allowing for detailed tuning in hybrid or bi-amp setups, while bridging options on the main channels offer even more configuration flexibility — including powerful 3-channel or 2-channel modes for specialty applications.

Balanced differential inputs make the X2 1100.5 compatible with a wide range of factory and aftermarket systems, simplifying OEM integration without the need for additional adapters or processors.

Wrapped in ARC’s refined Level 2 cosmetic package, the amplifier features a brushed silver hairline aluminum top, a rotatable illuminated acrylic badge, and integrated LED diagnostic indicators for easy setup and system monitoring. Whether you’re building a stealth install or a show-ready layout, the X2 1100.5 combines beauty, brains, and brawn into one amplifier.
