Arc Audio Subwoofers
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.
