How to adjust the audio system in Mercedes-Benz E300?
4 Answers
The audio system in Mercedes-Benz E300 can be adjusted in the following two ways: 1. Increase both treble and bass to +6, set midrange to zero, and adjust the overall sound field by moving it towards the rear seats to -3 or -4. 2. Set the bass to the highest level, adjust midrange to 4/5, and treble according to personal preference (recommended at 2/3). For speaker position adjustment, set the left-right balance of the auditory center to 0 and the front-rear balance to -5. This maximizes the use of the front bass speaker volume. Below are some recommended audio settings for Mercedes-Benz E300: 1. For vocal music, set treble to 70% and bass to 50%. 2. For rock music, set treble to 70% and bass to 50%. 3. For DJ or slow rock music, set treble to 40% and bass to 70%. 4. For pop music, set treble to 60% and bass to 70%. 5. For styles like Black Duck or Tong Li, set treble to 75% and bass to 70%.
Last time I spent quite some effort adjusting the audio system in my Mercedes-Benz E300. The key was finding the sound settings in the central control screen. Click the settings icon in the main menu, enter the sound options, where you can drag sliders for bass, midrange, and treble. I usually push the bass up two notches to enhance drum beats, and add one notch to treble to make vocals clearer. Remember to turn on the surround sound effect, which makes the music flow throughout the cabin. Different music styles require matching settings - max out the bass for electronic music, but tone it down for classical. Don't make adjustments too complicated while driving, safety first. Occasionally getting a system upgrade at the 4S shop can further improve audio performance, but these daily adjustments are usually sufficient.
Friends accustomed to German cars know that Mercedes' audio adjustment is quite user-friendly. Swipe left on the touchpad on the right side of the steering wheel to enter settings, select the sound symbol, and start adjusting. The core lies in the three EQ sliders: boost the bass for strong low-frequency torque, keep the midrange neutral to prevent muffled vocals, and moderately enhance the treble for more dynamic instrumentals. Often overlooked is the soundstage positioning function—setting the sound focus to the front row enhances immersion for the driver's seat. I've tested it myself: using lossless music and keeping the vents clear of clutter noticeably optimizes sound quality. If you suddenly want to switch styles, don’t panic—just call up the preset jazz or pop mode, which is much easier than manual adjustments.
Adjusting the audio system is actually quite simple—just give it a try and you'll get the hang of it. Tap the settings on the central control screen to enter the sound options, where the main page directly displays two control sliders for bass and treble. When sliding them, keep your ear close to the speakers to hear the most noticeable changes. When I first got the car, I followed online tutorials to tweak the parameters, but later realized the factory presets were actually tuned for the cabin's acoustics. If rear passengers feel the sound is too low, you can adjust the audio balance settings to shift the soundstage focus backward. For a surround sound effect, remember to turn on the Burmester surround function in the audio system—closing all windows will make the effect immediate. During regular maintenance, ask the technician to perform a sound field calibration with the diagnostic computer—it's more reliable than tinkering on your own.
