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 100kHz. 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 100kHz.

4 channels of dynamic sound

Enjoy powerful audio throughout the entire car, thanks to a 70W 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 aluminium casing, which keeps things stable for low distortion.

• Heavy-duty casing
• Input dials

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 audio².

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 favourite songs with this 4-channel amp

Enjoy 70W 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, minimising distortion. You can also independently adjust the volume of different frequencies to find the perfect balance for each song.

• Standard
• Enhanced

Flexible installation

Choose from multiple mounting options

The XM-GS4 can be positioned in a number of different places throughout the car. Install it in the front for easy access to controls, or put it in the boot to save on space.
