Your Harman Kardon Audio system...




Also, a nice PDF:

Honestly if I was out somewhere and someone introduced me to the guy that invented "Alumaprene" I would not be able to stop kicking him in the *****.
Like, they would have to taze me. Multiple times.

Nothing to me sounded as good as the Mark Levinson stereos that Lexus has been installing in their LS models for years. You could hear each individual instrument in a concert hall. They were a little lacking on thumping bass, but I don't think they were trying to appeal to thumping rap music.
The problem is that people become accustomed to hearing their music presented in a certain way, usually with exaggerated bass and highs. Kind of like when you see a TV on display in a store and they have all of the brightness, contrast and color saturation maxed out. It grabs your eye but really in order to have true detail you have to back down the eye candy. The resulting image doesn't "pop" as much but the detail can reveal itself.

The Best of Mercedes & AMG
THE HK in the W221 is not that bad.....it sounds better than all Bose systems I've had in the past (Acura, Infiniti.....some GM products)
The best Bose system I ever head was in my old man's 86 Caddy Coupe D'ville. Listening to the heartbeat in the beginning of Dark Side of the Moon....when you closed your eyes you really could not tell where the bass was coming from....sounded like it came from the front & rear (only 4x6 speakers up front)
No Quarter from Led Zeppelin sounds thick & smooth.
No highs, no lows.......it must be Bose!
I will soon add a JL sub & my trusty JL amp to the Benz when I muster up the courage to tackle the back seat removal to access and remove the stock "subwoofer"
The W220's Bose system was almost universally loved by owners, whereas the W221 HK system is almost equally reviled. Actually, the one area I can't complain about, after adding a little EQ, is the bass response. The two 8" subs in the front doors hit really hard once their EQ is corrected, and the same for the 8 x 12" on the rear deck. I just had to Hushmat everything to stop the car from rattling.
The problem with the 221 is a combination of a midrange heavy factory EQ, over attenuated bass in the factory EQ, and excessively bright drivers in the front doors. That, combined with minimal tone controls in COMAND.
Is your JL sub in a box? If so you'll want to cut open a portal between the rear seats otherwise the thing will be pounding away back there and you'll barely hear it. MB builds really isolated trunks.

I can pretty much work with any stock system and get it to sound how I want without getting into major equipment replacement, but the 221 HK really presented much more of a challenge than I was expecting for an S Class. I did ultimately get there and it wasn't hugely expensive, maybe a couple grand total, but it was a pain in the ***.

The Lexus ML system I could have it on full blast and would not distort. The bass was nice and didn't drown out the vocals, it would even shake the rear view mirror.
I did blow the sub once, and I had to purchase one off eBay for $750. I didn't attempt to install it myself due to my Lexus having the optional shiatsu massager in it and the entire back seat, fridge, rear deck lid had to come out to install the sub. Cost another $300 in labour to replace the sub.

The lack of bass is entirely a self-inflicted wound by Mercedes. The factory EQ emphasizes the mids (again, the 4" front door speakers) and kills the bass, and my guess is they did that to avoid complaints of rattles. The good news is that buried in all that crappy EQ is a very powerful and capable 14 speaker system with a 600 watt amp and digital signal processing. There are three stout shallow mount subwoofers in the car and they will shake the rearview mirror with no difficulty at all. The mids can be tamed without killing all the highs.
My solution is to put a 7 band graphic equalizer in the glove box, pull power for it from the 12v receptacle in the glove box, and run the output from the EQ into the car's aux in jack, also in the glove box. Run a cable from your smartphone to the input on the EQ and you're in business. The whole install is tool-less and takes about ten minutes.
With the EQ, you just dial up the bass (it will give you more than you'll ever actually want) and push the mids into the basement. Several members have done the mod and I've had nothing but great feedback from very happy guys.
See the write up in my blog (the link is in my sig). I guarantee you'll start listening to music in the car again.

Great, informative post, Mike. I appreciate you sharing your experience with us.

My car is a 2007, so I don't have the RCA jacks in my glove box any way. I'm not sure I have any in the car in any location. Do you know of any solutions to run the EQ to control all audio sources?

For a global solution you'd need to do as I ended up doing and strategically replace some speakers. Obviously in a 600 you're probably not going to want to flush mount aftermarket tweeters like I did, but the whole speaker upgrade can be done entirely behind the factory grilles and you'd never know anything was touched.
Now you can, of course, get quite a bit of flexibility out of your Aux In if you're willing to use your phone as a source (or buy a dedicated device like an Ipod for the car) and install an outboard EQ. You can get the XM app and stream your account from the phone, there are streaming versions of a lot of FM broadcasts, you have Pandora streaming, Spotify, Rhapsody, Amazon all have streaming subscription services, and of course you can put local files on the device itself.
The apps do work on your local files though, so it would be an easy way to test the effectiveness of EQ. I know you're an Android guy but in my experience I've yet to hear an Android EQ or DSP app that didn't give the sound a very heavily colored "processed" artifact. But there are a ton out there and I didn't try a whole lot. Generally a software EQ app is altering files on the bit level and that's hard to pull off without a really good DSP chipset (like in the Audisen Bit1). Although the new high end Samsung phones may be able to pull it off.
The only software based EQ I've auditioned that added nothing but good EQ is the AudioForge EQ app (IOS). I'm actually on the Beta team for the upcoming release and it's a great sounding, refined app.
On the other hand, the Glove box EQ mod works on everything you run through it...streaming files, local files, etc.
