Radio/speaker issue

[Tymad]

Was driving home listening to the radio. I heard a loud crackling/pop sound and the music stopped playing. Everything on the display screen is working properly (ex. Navigation, radio presets, climate settings), but no sound is coming from the speakers. I have checked all related fuses in the trunk and glove box, but no blown fuses. I also plugged in my iPod and it dispayed, but no sound. I was thinking it could be an amplifier issue, but not sure. Does anyone know where the amplifier is located and is there a fuse? Any thoughts?

Thanks

Sounds like the amplifier to me.
The amplifier is located behind the left trim panel in the luggage compartment.

I agree with stevelp99l. Whenever you dont hear audio on the speakers I would start with the fuses, then check the amplifier.

It is also possible that your fiber optic audio connection got disconnected somewhere.

Since you have iPod interface - i would check the connection behind the iPod interface to ensure all connections are mated properly.

Well i believe it is the amp but I actually found another problem. When I pulled off the rear panel in the truck everything behind it was wet. I forgot to mention it was raining when the radio cut out. It looks like the amp and whatever else is back there may have shorted out due to the moisture. I dropped it off at he stealer so I'll see what they come up with. Thanks for the help guys.

I had the same thing happen to me with my 5 series when they installed the tint. My speakers started clicking and humming and then nothing. I let it dry out and cleaned the fiber connector. Thought for sure I would need a new amp. Well, after about 3 hours it started working again and had no other issues. Reckon got lucky. And yea, its placed in a poor location......

Moisture or water in the trunk is a must fix ASAP issue.

The battery is there, relays are there, amp is there, lots of electronic stuff back there and as you all know - moisture or water and electronic stuff dont get along very well. And moisture starts corrosion.

I suggest you get that fixed ASAP.

I have the same issue. Any updates?

I had something similar in the past. I would get a loud static noise through the speakers for up to a minute then it would go away. Nothing ever stopped working. After multiple trips to the stealer they finally replaced my amp and all has been well. Here is a link to my post. Annoying Static

My issue is on a M6 2006. The sound from the speakers play for about 1hour then starts cutting on and off. Almost like the amp is overheating? Anyone here have instructions of removing the rear cover in a M6 to get to the amp?
