Hello, I have a C300e 2023 with the burmester sound system. I am picky when it comes to sound systems and want it to sound perfect, but recently, when playing songs at 60-70% volume, something on the driver side interior rattles when the bass comes in. Even the slightest bass makes it rattle.

I cant seem to locate the rattle but I know it is on the driver side interior, either in the door or somewhere on or inside the dashboard.

Can it be the speaker being damaged or is something rattling inside? Does anyone have any experiences with this or know what I can do to solve this?

Thank you in advance.
