Question1991 sl500, music keeps cracking and fading
AnswerThat could be a multiple of things, loose wiring, bad Speaker, bad head unit and so on.
Fist identify which speaker is causing the problem by using the fade and balance to pan the music to front left, front right, rear right, and rear left.
If all speakers do the same thing your problem is most likely the main head unit in the dash. Check the connections to make sure they are seated properly and there are no exposed copper wires.
If it is isolated to just one or two speakers your problem is most likely on the speaker end. Check the connections to each speaker and that the speaker is physically intact, not ripped loose or physically disconnected from the from the round base,or damaged. Be care not to damage it if it isn't damaged speakers can be fragile if forced.
If you are not comfortable with doing the troubleshooting your self I recommend bringing it to a service center.
