tomz_racing,
As it is a bose sound system for C class, i think it is possibly the same problem : but, go ahead with those subs install and if you got the problem , simply disconnect the microphone. it's done in 5 minutes time.
And then... enjoy Whopping Bass ;-)

You will definitely have that problem as well. Disabling the microphone is the only sure fire cure I know of. Although it's been said that setting the Speed Sensitive Volume to 0db in DAS can help in the non-upgraded Bose system.

Is that right?
I'm not so sure that what wimpytron said about the Speed Sensitive Volume Adjustment being already disabled on a Bose system is right. I have a non-modified Bose system in mine and I got wildly varying volume... had the dealer turn it off and voila, no more problems. The AudioPilot still adjusts the volume but it's not nearly as annoying as before.
Maybe it varies with model year or manufacture date, but that still might be a solution for someone who is not fighting with an aftermarket sub or amp.

Disabling speed sensitive volume control will NOT solve this problem. At least in my car it didn't. I've tried that.
Tomz_racing,
Apprently this mic detects the ambient noise level and 'tries' to adjust the volume. However, with the after market amp/subs installed, there's a problem with sudden volume increase that can cause damage to the subs.

Btw, the mic you are all talking about, is this the same one that is used for the Teleaid? I'd imagine if you removed it, that's it for the service.

Jade Lotus,
I thought we were discussing about the problem that BOSE systems has after installing aftermarket amp/sub without changing the head unit. That's why I said the mic needs to be taken out if you have the same problem that I do.
No, The mic that I disconnected and mentioned in the last few posts of this thread is not for the teleaid. The Teleaid mic is located near the rear view mirror in a black circle. I disconnected that as well while in search for the correct microphone. You don't have to do it.

Fair enough, just trying to make the point that it's not a foregone conclusion it's disabled if you have a Bose system.

jadelotus : that the volume speed control IS ALREADY disabled when BOSE SOUND SYSTEM is installed is a sure thing. the german technician said that it interferce with the Audio Bose Pilot, that has the about SAME FUNCTION, but much further developped than this normal volume increase
see the following email:"
The standard GAL (speed dependend volume control) needs to be deactivated!!!
The audio pilot function in conjunction with the GAL does not work properly -
it overshoots and requires constant manual adjustment.
Please have your technican check for it, but normally, by default it is turned off."
I had this checked and the Benz technician said it was already turned off.
This is THE ONLY TRUE explication. And I believe this technician has he was the only one to give me any correct information

Alright, I didn't mean to hijack the thread on the issue. Maybe someone turned it ON, beats the hell out of me... I definitely have the Bose system and I definitely had an issue with ridiculously conspicuous volume changes in my car. Since the audio pilot cannot be turned off, and the last time I took it in I had them disable the speed sensitive feature, which resulted in no more volume spikes (except for some very slight changes from the audiopilot) my only conclusion could be that the speed sensitive was enabled.
My only purpose on bringing it up is to clarify that unless my car is a freak of German engineering, or some speed-sensitive-enabling gremlin is chewing on wires in my vehicle, there may be some others floating around out there with it on.
Alright?
I concede the point! It's a Friday night and I'd rather be driving my car than talking about it!

No, but I do work for a dealer, so I drive many, many cars.

Speed Sensitive Volume control IS turned on by default and set to plus/minus 6db. My problem is that my dealer claims they have no way of changing that thru DAS. I know they can, don't know if they're just lazy or stupid.

Yes! this works.
BTW just a recap, I found this thread last night and removed the little mic shown on page 5. This is an excellent fix to a tiresome problem. [ No, I dont have an external amp, just a Bose that thought it knew "volume control", but didn't.]
This is supposed to be just the ambient noise sensing mic, but it also appears that the VSS volume is no longer acting up in my car!
Removing the mic defeated both problems for me.
Thanks one and all!

Wow, you truly saved my butt.. I just installed a JL audio subwoofer and amp into my CLK500 at the Good Guys, and as soon as we tested it, the volume shot up and down... the installer was all "I told you so... thats why I dont work on Mercedes", and I said, "watch this and learn", and I disconnected that microphone... man he was so happy with the results, he almost kissed me.
Thank you so damn much. WOOHOO!
