Hey guys I drive A 2007 E93, a few days ago I had no sound from my speakers!! Everything else works (Navi, HU) but no sound!! Could it be a blown fuse!! Or is it the amp

: cuz I heard the amps are very expensive!!!

Do you have iDrive or an aftermarket HU? Hifi? Harmon?

Battery could be low
The IBS system has the ability to shut stuff down if the battery is low to keep the car going.

google e90 electrical for the electrical pdf for and more detailed explanation.

Also I have heard of the amp fan going out.
