How many of you kept your factory sound system?

My car has the Logic 7 system fitted & I'm pretty happy with it as car sound goes.
I have the oem bose system, and its perfectly balanced between bass and high notes.

The only thing that i dont like is that the headunit turns the volum down a bit when im slowing down like getting of the motorway.. does anyone know how to deactivate that function? I have the prefacelift comand..

I replaced all 4 speakers,2 tweeters, 12" sub, amp, DVD headunit all Kenwood. I wanted more bass and I got it lol. Wondered if any1 kept all speakers but upgraded only the sub.
I have no intentions of replacing the CLK's factory system. Even though everyone says the COMAND NAV is hard to use, but I swear I find it easier than using the AVIC or the system in the wife's Jeep. Basically, the major annoyance is using the joystick to enter letters - it's too bad they didn't allow using triple-tap on number pad (like sending text messages before smart phones). I only listen to SIrius and iPod, both of which I have as factory options in the CLK and they work just fine. All I need to do is add the Bluetooth interface and I'm set.
I usually have the rear passenger right side door open so the bass direct blasts directly into the cabin. Sounds amazing to me!
Will dynamat eventually.

Let me assure you that a genuine 500 watts RMS from one channel in a car would make your ears bleed & cause permanent hearing loss.
The practice of adding the power of channels together to give a total ouput is also misleading.
Then there are issues such as speaker efficiency to consider. Ouput at a specific frequency or range at 1 metre for a 1 watt RMS input.
Higher power does not = better. Total distortion at the specified level requires consideration.
Don't be fooled by the power claims numbers game. Quality of reproduction has nothing to do with watts. All you need is enough to drive a specific speaker to a level below which unacceptable distortion occurs due to cone breakup, thermal issues or amplifier clipping & to be able to do that continuously.

The only other method is to find a decent shop that can do a frequency sweep of your car & try to flatten the measured sweep response with the graphic equaliser. Car acoustics measure terribly with wild peaks & suckouts.
with all the bells and whistles, i considered it pretty useful compared to what I used to had. My only regret now (about 3 years later), i feel like i could use a smaller sub and box so it would take less room OR made it so that it mounted to the where the stock sub is located... but i didnt want to cut into the car or anything.
My speaker set up is currently 280Watts peak 80-120 RMS, 6.5 inches each. 12 inch bandpass sub, mono class D amp 1000Watt peak 300 RMS. all these should be better than Bose but apparently I didn't adjust or tune it so it kinda sounds decent but it could be better,

The number of speakers depends what you are trying to achieve. If you want to create some sort of stereo soundstage in a car you don't want too many speakers.
If you are trying to achieve a quasi surround sound then the more the merrier within reason. The rear shelf is not a great place to mount speakers due to UV exposure. Yes I know Benz usually stick the sub there.
One problem with modern speaker design is that some of the finest drivers have the lowest efficiency. In fairness these are not the sort of drivers you would mount in a car.
Trying to achieve really refined sound in a car is extremely difficult & expensive & you can do a lot of damage to a car in this pursuit. I personally can't stand the sort of thumping ghetto blasters that some people try to build into their cars. I like things to sound natural & realistic.
No car needs a 12" sub. You would be better off with a decent tight 10 inch W7 from JL Audio or similar.
It sounds as though you have enough power. I would start by getting the most out of what you have first before considering any more speakers & amps.
She actually has the idea that she needs a second sub (and amp!) in the C240 because she doesn't get enough bass. Sheesh! Kids!
Ps sub takes up more then half but still usable, groceries yes, set of wheels? No LOL
