- CEA-2006 Compliant — Standardized “Voluntary” Testing & Measurement Methods for Mobile Audio Amplifiers. This standard advocates a uniform method for determining an amplifier’s RMS power and signal-to-noise ratio. Using 14.4 volts, RMS watts are measured into a 4-ohm impedance load at 1 percent Total Harmonic Distortion (THD) plus noise, at a frequency range (for general purpose amplifiers) of 20 Hz to 20,000 Hz.

What kind of amplifier is the Sony XM-GS100?
The XM-GS100 is a monaural (mono) Class D amplifier designed to power a subwoofer channel.
How much power does the XM-GS100 output?
It delivers 330 W of high power output, with a maximum of 600 W at 4 ohms and 1100 W x 1 at 2 ohms.
Does the XM-GS100 have adjustable bass and crossover controls?
Yes. It includes a variable low-pass filter (50–300 Hz), a subsonic high-pass filter (6–70 Hz), and a bass boost adjustable from 0–10 dB at 40 Hz to enhance low-frequency impact.
Can the XM-GS100 connect using RCA or speaker-level inputs?
Yes. The amplifier supports line (RCA) inputs and speaker-level (high-level) inputs, allowing direct connection to factory head units without RCA outputs. It also features a line-out pass-through for system expansion.
What protection and stability features does the XM-GS100 include?
It features Active Thermal Control, which regulates operating temperature for stable playback at high volume, and a Dynamic Distortion Suppressor that reduces distortion for clearer bass reproduction.
Is the XM-GS100 suitable for compact installations?
Yes. Its compact chassis and single-sided connections offer flexible mounting options, making it well suited for installations in limited spaces.
What impedance loads is the XM-GS100 stable at?
The XM-GS100 is stable down to 2 ohms and is not rated for 1-ohm loads. It outputs 600 W at 4 ohms and up to 1100 W x 1 at 2 ohms.
Does the XM-GS100 require a remote turn-on wire?
Not necessarily. The high-level input includes auto sensing, which can turn on the amplifier without a dedicated remote turn-on wire.
How much does the Sony XM-GS100 Monaural Class D Amplifier cost?
MSRP is listed as $199.99. Given that, these models can go on sale from time to time, and there are several other opportunities to save on price like through their group discounts for education, healthcare and military/veterans (ID.me & Unidays) along with their free loyalty program that gives up to 5% back in points.
