Versatile Power with Show-Grade Style and Perforamance
The ARC Audio X2 600.4 is a high-performance 4-channel amplifier designed for systems that demand clean power, real-world flexibility, and professional-grade results. Part of the X2 amplifier lineup and equipped with ARC’s refined Level 2 cosmetic package, it features a brushed silver hairline aluminum top panel and an illuminated rotatable acrylic badge — all with top-mounted illuminated acrylic logo panel equipped with advanced diagnostics indicators fast and easy troubleshooting.
Delivering 150 watts x 4 at both 2 and 4 ohms, the X2 600.4’s impedance-switching output stage ensures consistent power across system loads, while balanced differential inputs allow seamless integration with both factory and aftermarket source units.
Channels 3 and 4 feature fully adjustable bandpass crossovers, providing advanced signal control within the amp for a wide range of system designs. Whether you're building a system with coaxials or passive components, bi-amping 2-way speakers with external crossovers, feeding amplified channels into a DSP-based active system, or running bridged outputs for a small subwoofer, the 600.4 is flexible enough to adapt.
The amplifier also offers full bridging capability — allowing channels 1 and 2 or 3 and 4 to be combined for higher-output mono channels. This makes it possible to configure the X2 600.4 as a powerful 3-channel amp (e.g., two speakers and a sub), or even as a robust 2-channel amp delivering high power to a set of specialty drivers or midbass units.
With compact dimensions, installer-focused engineering, and clean, authoritative performance, the X2 600.4 is the versatile tool your system has been waiting for.
