Setting the equalizer
The acoustic characteristics of the car inte- rior affect the quality of the sound repro- duced in your vehicle to a much greater ex- tent than the speakers.
Position, installation and the rear volumes of, for example, the door or rear window shelf all play an important role.
Even the sound produced by well selected and installed speakers can be affected neg- atively by resonance frequencies in the ve- hicle interior.

Notes on making the settings
The following notes are intended as recom- mendations only. They do not necessarily reflect your own personal sound preferenc- es.
We recommend that you use a music CD you are familiar with to make the settings. The CD should include tracks with different instruments and vocals. Purely electronic music is not well suited to serve as a basis for making the settings because the original sounds cannot be determined.
Before you set the equalizer, set bass, tre- ble, balance and fader to “0”.
This setting is described in the Quick Refer- ence under 8 AUD.
Now listen to the CD you have selected.
Evaluate the sound according to your own personal preferences.
Now refer to “Sound impression/problem” in the table and you will find suggestions to eliminate any problems under “What to do”.
