More sound, less noise
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
Sony XM-GS4 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 favourite 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.
