【ARC Audio X2 650.1｜Monoblock Amplifier for Subwoofers】

You added a subwoofer, but now only the bass stands out. Or perhaps you want to enjoy a deeper, more powerful bass. If so, ARC Audio X2 650.1 is for you.

This monoblock amplifier is designed specifically for subwoofers, narrowing its output band to 10Hz–230Hz and focusing on reproducing low frequencies. At a 1Ω load, it supports up to 650W of output, driving a single subwoofer or a dual subwoofer setup with mid-level output with confidence. It adds thickness to the bass that forms the foundation of music—not only delivering impact when you turn the volume up, but also making the presence of vocals and instruments easier to feel.

Equipped with balanced differential inputs, it’s easy to integrate into systems based on factory audio. Depending on your system configuration, you may be able to connect directly from the speaker outputs without using an external converter. It’s also a great choice if you want to strengthen your subwoofer without replacing the OEM navigation unit.

The unit uses a compact black steel chassis, making it easy to lay out even in limited spaces. Since you can remove the top panel to access tuning and connection terminals, it’s designed with post-installation adjustments and maintenance in mind. When strap-connecting two units, it can supply up to 1100W for a 4Ω load.

However, when choosing a subwoofer amplifier, selecting only by output power can sometimes throw off the balance with the front speakers. To connect the bass naturally in your vehicle, it’s important to consider not only the subwoofer selection, but also the installation method, gain and filter settings, and even the power wiring.

At LOGON, we organize the details together—reviewing your factory audio specifications, current system, the music you want to listen to, and how you use it—to determine whether a configuration using the X2 650.1 truly makes sense. If you want to enjoy bass properly but don’t want it to sound out of place in the cabin, feel free to contact us first.
