This package is dedicated to the most demanding customers who wish to get the best possible sound with no compromises. This solution will give you deep bass, high clarity and very loud volumes with no distortion.

Using a high-end DSP amplifier combines two of the most important functions in sound signal processing – amplification and sound tuning. In conjunction with new underseat subwoofers, front, centre and rear speakers the achieved results will leave you astonished.

This amplifier, developed specifically for BMW, powers up each driver in the vehicle with a much stronger and cleaner signal. At the same time, the embedded DSP (digital signal processor) allows us to professionally tune up the entire sound stage with results similar to those of a home cinema.


Briefly, the sound tuning consists of:

  • Speaker polarity check
  • Volume optimization
  • Correct crossover setting
  • Time alignment
  • Equalization
  • Sound image fine adjustment
  • True centre speaker setup
  • Dynamic bass enhancement
  • Subbass extender
  • Adjusting the sound stage to the customer’s preferences

Installation of these packages start from $1250 incl GST.

For the basic BMW sound system version lacking tweeters, we can supply OEM BMW tweeter domes to fit component speakers and achieve improved sound quality. Cost: $350 incl. GST
