Mercedes GLE audio failure resolved

My 2015 Mercedes GLE with a gasoline engine has complete audio failure at 273773 km. There's no sound from any source. I've tried radio, USB, and auxiliary input, but there is complete silence. I suspect the bass speaker, but I want opinions before disassembly. I've checked basic connectivity and the sound quality was excellent before.

I had a similar issue with my GLE. Check the amplifier in the rear cargo area. It might have gotten wet or shorted out. That killed my entire audio system. Look there before assuming it's the bass speaker.

Thanks for the tip. Where is the amplifier located? Is it easily accessible, or will I need to remove panels? Also, were your symptoms the same, complete audio loss from all sources?

The amplifier is behind the trim panel on the left side of the cargo area. You'll need to remove some panels. Yes, complete audio loss. After checking the amp, consider a workshop. They'll diagnose it properly.

I checked the amplifier as suggested and took it to a shop as you recommended. Turns out the bass speaker was defective, causing the system to shut down as a protection measure. Repair cost was 280€. Thanks for pointing me in the right direction.
