Lexus LX Audio System Failure

I have an LX and experienced something similar. Did you notice any sound distortion or volume control issues before it completely cut out? Is Bluetooth connectivity affected, or is the entire sound system unresponsive?

Before it died, there was some noticeable sound distortion at higher volumes, particularly with bass-heavy music. I didn't pay much attention then. Bluetooth connects fine, but still no sound. All audio system functions seem to work – I can change stations, select different inputs – just no audio.

Okay, the distortion before complete failure points to a speaker issue, possibly the bass speaker as you suspected. Given the complete lack of audio output even with Bluetooth connected, it might be more than just one speaker, or the amp. I'd suggest taking it to a workshop for a proper diagnosis, before trying to troubleshoot on your own.

Thanks for the insights. I took it to a local shop, and you were right – it was indeed the bass speaker, and the amplifier was damaged as well. Repair cost was 280€.
