I was recently facing the same issue and was looking for solutions or fixes. Bass drops intermittently and had crackling noises. There is another thread which is almost a year old discussing similar issue.

Visited the dealer and let them know about the issue. It is hard to recreate and just left the car with them for investigating. They ran diagnostics and found fault codes related to the amp and identified as bass booster failure.

Had to special order the part from germany and took about 2 weeks. Now the issue seemed to have been fixed (3rd week now).

Hope this helps and I would suggest to visit the dealer. Looks like a known issue at some dealerships.
