Right front speaker distortion

Trying to figure out root cause of distortion. It is only the right front speaker. I checked the HK speaker by removing the door panel to see if it had become loose. Nope. I took an old Alpine R series 6.5" and it produced the same distortion at certain frequencies/volume. Would it be the amp? Any ideas and alternative tests I should conduct..please advise.

I'm relatively new to M3's (not new to BMW's) is this a common problem? Has it been determined to be the amp or something else? Lastly, any ideas on a remedy?

It can be radio module/sound processor, known as BM54 or BM24 depending on audio system and MY of the car.
Try searching the internet for BM54 or BM24 radio module, so you can get an idea of various problems it can cause.

For instance, I have a problem when I turn down the volume, it makes distortion sound on all speakers (amplifies bass and mid-bass, kills tweeters and generally turns up?!?! the output, until I completely turn it down/mute).

It is located in left part of the trunk (silver box with one square connector), bellow navigation dvd/cd changer, accessible when you remove trunk liner.
