What to Do When the Mercedes-Benz Audio Suddenly Has No Sound?

[StAlexander]

If the Mercedes-Benz audio suddenly has no sound, first check if the CD player's power supply is normal. As long as there is power, the indicator light should be on, and the CD player's compartment should open and close normally. If there is no power, check the power supply, including the fuse box and wiring. The technical indicators of car audio include: 1. Output Power: Most of the power ratings labeled on current main units are music power, ranging between 40W and 60W. The power should not be too large. 2. Frequency Response: The frequency range audible to the human ear is between 20Hz and 20KHz. Therefore, this indicator should at least cover this range, and the wider, the better. 3. Signal-to-Noise Ratio: This refers to the ratio of the music signal to noise. Generally, high-end car audio systems have a ratio above 90DB. The higher this value, the better. 4. Harmonic Distortion: This indicator reflects the fidelity of sound reproduction. The smaller the value, the higher the fidelity, and the better the audio effect.
