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.

Aluminium case absorbs external vibrations
    The heavy duty, heat sink integrated aluminium body of this amplifier is designed to prevent external vibrations, for jitter-free sound that stays true to the source.

Dedicated control section for fine-tuned audio
    The amplifier's control section, located just under the external cover, provides users with the ability to manually adjust aspects of their in-car sound — including resistance and the level of power flowing through each individual component. The XM-GS4's carefully selected components are highly reliable and noise-resistant, minimising unwanted distortion. The twisted wire structures help to further cancel in-car noise, providing a cleaner overall sound.

MOS FET transistor for efficient power delivery
    The metal-oxide-semiconductor field-effect transistor (MOS FET) is engineered to deliver a high output from a low-current input. This allows it to provide power to the amplifier's circuits quickly and efficiently, for more responsive operation.

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.

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.

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.

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.
