Premium cars deserve premium sound – the basic speaker setup in BMW 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 C42BMW-FRT.1 with car-specific baskets 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, e.g. the BMW-specific UP 7BMW, these speakers reveal their full potential in respect of dynamics.


  • Exclusively developed speaker system for BMW vehicles
  • Car-specific baskets and connectors for easiest installation
  • Perfectly tuned component system with optimized frequency response
  • High quality crossover with bridgeable highpass filter for perfect operation with a DSP amplifier
  • Perfectly combinable with further MATCH UPGRADE components – e.g. DSP amplifier
