Enjoy the subtlest nuances of studio-quality sound in higher than CD quality with High-Resolution Audio. Passion for music unites every component from signal to speaker so it feels like the artist is performing right in front of you.
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.
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.
Our carefully selected potentiometers are highly reliable, for consistently minimal noise. The twisted-wire cable structure provides additional noise resistance from electromagnetic interference.
Our premium diodes experience a lower voltage drop than conventional diodes, enabling faster switching and better system efficiency for smoother, more stable audio.
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.
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.
Take your in-car sound further. Our premium on-road audio products are all designed to complement each other, so you can build the perfect audio soundscape for your car.
