Weird audio problem with the H&K system on S212
So, I recently bought a 2010 S212 with the Harman Kardon sound system, but the bass is very low or pretty much non-existent. I can hear the subwoofer working, but the door speakers produce very little bass, to the point where it's barely noticeable. The bass is already set to +10 in the sound menu.
What bothers me is that I went into the engineering menu on the NTG 4.0 and found that under both the Audio Parameters and EQ Parameters sections, all of the settings are empty. No values are set, and the options are grayed out, so I can't change anything.
How can I fix this?

Not much bass in my W212 so I investigated and the woofers in the front doors were faulty which seems to be a common problem.
The originals are mounted in a weird HK surround which to me seems to be just a fancy engineering exercise
I found some 6.57" (167mm) speakers on ebay with specs 600watts music power, good sensitivity 93dB, frequency response down to 60Hz
At $20 a pop worth a try. They wouldn't fit inside the HK surrounds so I cut away the flange with a power jigsaw to mount the speaker on the outside.
I cut the old speaker out and trimmed a larger circle cut out to fit, cut some plastic off the connectors and bent them up.
I used a bead of black silicon between the HK surround and the speaker flange to make a seal so that the baffle works.
Pop rivetted the speaker on the HK surround and pop rivetted the HK surrounds back on the doors and plugged them in.
Amazing result. Good as new and possibly better. Booming bass for a bit over $40.

BUT note not to play with "reset" or "factory reset" you unit to ignore your car until factory recoded with MB Tools. At least it is one issue you wont have to face.
