GLK Audio System Failure

My 2015 Mercedes GLK with a gasoline engine has a completely silent audio system, even though it recognizes auxiliary input. The volume control seems to work, but there's no sound. I suspect a bad bass speaker, any thoughts?

Radio silence is the worst. I had a similar problem with my old Volvo. Check the fuses. It seems basic, but that was my issue. The fuse looked fine, but was actually blown. Worth a shot before you start tearing things apart.

Can you tell me which specific fuses you mean? I know there are multiple fuse locations, so knowing which ones to check would be great.

I can't remember the exact fuse number. It was a while ago and a different car. But check the ones related to the audio system, amplifier, and maybe even the auxiliary input. Your owner's manual should have a diagram. If the fuses are all good, I'd say it's time to let a professional take a look. Save yourself the headache.

I checked the fuses you suggested, and they seemed fine. I then spoke with a technician, who confirmed it was a defective bass speaker. The repair was 280€, including parts and labor. The audio is working again.
