Bring your in-car audio to life
The XM-GS4 4-channel amplifier is engineered to enhance every track—including High-Resolution Audio files—thanks to an ultra-wide frequency range that extends up to 100 kHz. A range of premium circuit components work together for ultimate efficiency and pitch-perfect sound reproduction, so you can give every road trip the soundtrack it deserves.
Fine detail across the whole spectrum - Hear thundering lows and soaring highs brought to life, with an ultra-wide frequency response that extends up to 100 kHz.
4 channels of dynamic sound - Enjoy powerful audio throughout the entire car, thanks to a 70 W x 4 RMS power output.
Hardwired for exceptional sound - Premium circuitry for optimum performance
Get the best from your in-car sound, thanks to the XM-GS4's hub of high-quality audio circuitry. Everything is engineered for minimal noise and maximum efficiency — including the heavy-duty aluminum casing, which keeps things stable for low distortion.
Capacitors - High-quality electrolytic capacitors assist in powering bright, versatile sound.
Transistor - The high-current transistor ensures fast, efficient power transfer for responsive operation.
Choke coil - Low flux choke coils in the power block deliver low-noise, high-quality sound reproduction.
More sound, less noise - Noise-resistant potentiometers
Our carefully selected potentiometers are highly reliable, for consistently minimal noise. The twisted-wire cable structure provides additional noise resistance from electromagnetic interference.
Total system efficiency - Schottky-barrier diodes enhance audio stability
Our premium diodes experience a lower voltage drop than conventional diodes, enabling faster switching and better system efficiency for smoother, more stable audio.
Low and high pass filters
Our high and low pass filters separate the audio range to deliver an accurate sound stage that's rich in powerful bass, clear mids, and pristine highs.
The power behind every track - Supercharge your favorite songs with this 4-channel amp
Enjoy 70 W of power from each of four separate channels, for more flexibility in setting up your ideal in-car sound stage. Using a bi-amplification connection, you can assign two channels to bass frequencies and two to high frequencies, minimizing distortion. You can also independently adjust the volume of different frequencies to find the perfect balance for each song.
