Arc Audio

The biggest challenge in modern car audio is finding an amplifier that fits in tight spaces without sacrificing the warmth and dynamic headroom of a traditional Class-AB amp. Arc Audio X2 Series amplifiers solve this by employing high-speed switching frequencies and heavy-duty copper rails to deliver massive power with minimal heat. Unlike budget Class-D amps that sound "dry" or "thin," the X2 Series features an optimized feedback circuit that maintains a high damping factor, ensuring your speakers remain composed and punchy even at maximum volume.

Choosing the Right X2 Model

Your system architecture dictates your amp choice. For a standard bi-amped front stage or a simple front-rear setup, the X2 600.4 is the workhorse, delivering a solid 150 watts per channel. If you are building a sophisticated "active" 3-way system (Tweeter, Midrange, Midbass) or need to power a full system with rear fill, the X2 1200.6 offers six channels of flexibility, including two "high power" channels (5 & 6) perfect for aggressive midbass drivers. For a complete "one-amp" solution that includes a dedicated subwoofer channel, the X2 1100.5 combines the 4-channel precision of the 600.4 with a powerful 500-watt monoblock section.

Technical Features

The "secret sauce" of the X2 line is its Microprocessor Class-D Design. This chip monitors current, voltage, and temperature in real-time, adjusting the power supply to prevent shutdowns during dynamic peaks. All models feature Balanced Differential Inputs, which reject noise from your vehicle's electrical system, a critical feature for modern EVs and cars with complex electronics. Additionally, the X2 1200.6 and 1100.5 (Level 2) models come in a stunning silver brushed aluminum chassis with a rotatable, illuminated badge, ensuring your install looks as premium as it sounds.

Installation Advice

When installing X2 amplifiers, utilize the Signal Sense Turn-On feature if you are integrating with a factory head unit that lacks a remote wire. Be mindful that while these amps are compact, their high-density power output requires proper ventilation; avoid mounting them upside down directly under carpet. For the X2 1200.6, use Channels 5 and 6 for your most power-hungry drivers (like 8-inch midbass or subwoofers) to leverage their ability to output 300 watts at 2 ohms.
