Sony XM-GS4: 70 W 4 Ω 4- / 3- / 2-Channel Car Stereo Amplifier

Enjoy the subtlest nuances of studio quality sound in higher than CD quality through 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.

Hear thundering lows and soaring highs brought to life, through an ultra wide frequency response that extends up to 100 kHz.  Enjoy powerful audio throughout the entire Car, thanks to a 70 W x 4 RMS power output.

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 through 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.

MOSFET transistor for efficient power delivery:

The metal oxide semiconductor field effect transistor (MOSFET) 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.
