speakers in the 2013 GLK model



VicViper has a DIY for Harmon Kardon replacement in the W204 forum used as reference.
I went the simplest route by replacing just the tweeters with OEM Harmon Kardon on my C300 and GLK350. You can find a thread that discusses the tweeter DIY and the OEM part number.
There is also a thread on how to adjust the equalizer through the engineering menu.
Search is your friend.
