Premium cars deserve premium sound – the basic speaker setup in Mercedes vehicles does not meet the expectations of ambitious music lovers in many cases. For all those, the tailor-made MATCH UPGRADE speaker systems offer the perfect alternative that opens new horizons of sound.
The 2-way component system UP C42MB-FRT.3 provides much better precision and dynamics across the whole frequency range combined with a fantastic treble resolution thanks to the 25 mm silk dome tweeter. Additionally its level is adjustable in three steps according to personal listening preferences.
Especially in combination with one of our DSP amplifiers these speakers reveal their full potential in respect of dynamics.


  • Optimized sound characteristics for Mercedes vehicles for a spectacular sound in combination with significantly increased power handling
  • Exclusively developed baskets and car-specific connectors for Mercedes vehicles for easiest installation
  • Separate crossover with 6 dB slope and 3-stage tweeter level adjustment
  • Perfectly combinable with further MATCH UPGRADE components – e.g. DSP amplifier
