harman/kardon® Logic7 not really powerfull
I have a 2005 E500 and use to own a 2003 E320 and I must say that I am not happy with the harman/kardon® Logic7® Digital Surround Sound System.
I think it does NOT crank out that much power, punch, i.e. Base! The louder you turn it up, the less rich the sound is.... It's it me or should MB put a better SUB system/SUB amp or amps in general in the car?
I also own a 2003 SL500 and the Bose system is the BOMB!!!!!!!!!
Anyone have any suggestions on adding an inexpensive aftermarket Powered SUB that can be hidden? NOT looking for an SUB that takes up any trunk space.

I had the Harmon Kardon on my e500 and have it now on my w221 s500...it rips the bose system to pieces...
any ideas why they are using bose systems on some cars and h/k systems on others...are they phasing out the bose system?
Not to say that the Harmon/Kardon system in the E500 is bad, by all means no, its great! But I would've expected atleast double the umph/thud considering it is double the wattage w/ the addition of a subwoofer. Now I know wattage isn't everything but I guess maybe I was expecting the margin of improvement to be alot more noticeable atleast.

I had an E320 Avantgarde W211 with standard sound system. Nothing wrong with it as far as factory sound goes.
Changed to a BMW 540i E39 with Logic 7 (BMW Branded) and the sound was ok. No difference really between the W211 standard sound and the L7 in the BMW in my opinion.
Changed to a BMW 645ci E64 with Logic 7 (BMW Branded) and the sound was really good. Much better than the E39 and W211.
Recently changed to a CLS550 W219 with H/K Logic 7. The sound blows the BMW systems out the water. Bass response is far superior and no drop in sound quality at high volume.
Compared to a friend's B&O system in his Audi A5 convertible the H/K7 system kicks serious but!
Now, it may not get to ear-bleeding loud, but it gets rather loud and still keeps high quality sound. (It is hard to push it to clipping levels - not that one would ever want a sound system to start clipping)
My main problem is that for stereo recordings, the "Logic7" equalization and "fake surround" adds a bit of harmonic distortion and misplaces instruments from time to time. Very disconcerting to me when I play a piece that I know well.
