Besides replacing the standard speakers, the HK Logic7 has amps/signal processors, additional speakers in the dash (center channel) and adds a subwoofer. It can be done, but the time and $$$ would be on the high side. When I bought my 2008 C300- the car had just been released and it was difficult to find one with options. I upgraded the tweeters in the A-Pilar and added an Infinity Basslink subwoofer for under $400 total and the sound quality was much better.

AkaSig:
Tapping the head unit to connect such a self contained sub, does this require a sound shop top pull trim and faceplates and head unit, too, or done from behind/under on a GL?
Also, anyone know if M/GL front door tweeter covers easily remove without taking off entire door panel to replace tweeters?
Not sure how I feel about who takes apart what, but I want these upgrades.
Bertha has 17000 in German options so ticked most all feature boxes as a used car choice - other than HK. Life is full of compromise.

The A-pilar tweeter covers are easily removed and do not require the removal of the door panels. The Infinity Basslink was installed by a high-end car shop (Ultimate Auto in Orlando)- I'm not sure where they picked up the signal for the subwoofer.

Dealership asked if it was possible for me, they even called Germany. Due to the the fiber optic cable running tonight to the wires and command not possible. Ended up trading that one in for a bluetec with a hitch and hk.

Adding speakers to factory set up?
Is it possible too add mid speakers, tweeters, a crossover and a 4-channel amp to the factory deck? I installed a 15" Kicker L7 sub, Hifonics amp and Rockford converter. Was hoping I can add two 10 inch Beyma's for mids and kicker QS tweeters, on top of the factory set up. I know its fiber optic. Ideas anyone? Thanks.

akasigfreak - $400 to upgrade the sound is a huge bargain, I'll look for that as a minimum, see what a little more might get me. I'm no audiophile when it comes to car audio, but the base system sound is surprisingly poor. Tinny and annoying, I'm sure that sub solves a lot of the problem.
arcangel - any luck regarding your question above?
