Low voltage causes speaker to crackle?

[NMT12]

Hey everyone,

I recently purchased an E92 M3 and never had any prior experience to the pre F series BMWs. I was on holiday and the car sat in the garage for about 3 days with no start ups. (I usually daily drive the M3)

As I was driving this morning I noticed the speaker had static and crackle but I didn't have time to check which speaker was faulty, although I imagine it was going through the front speakers. So I turned off the car for about an hour and tried it again and all the static and crackle disappeared. Will this eventually blow out my amp?

I have the Enhanced premium sound. Thanks!
