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.

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 audio1.

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.
