Audi Concert

[Neale_hardie]

Was driving home from work today and lost all sound from my stereo. My car is an 07 with the concert CD/Radio head unit with Bose. Everything is working display wise just getting nothing through any speakers. I heard a small crackle the other day through the speakers but never took any notice as it continued to work until today. Tried doing a search also.

Any help grateful.

First thing I'd check would be the fuses for the Bose amp?
Seems a logical choice then if that's ok inspect the amp

Checked the fuses for the Bose amp then tested the power to the amp via the 4 pin plug and took readings, I then took a reading to the speaker in the sub.

But still no sound from any speakers

Just a wee update managed to get to the bottom of my problem.....in the end it was the Bose amp that had failed.
