W221 speaker issue

[RuS]

Hi Bros

Finally, I just gotten my W221 after scrapping my W211 (wanted to renew but in the end didn't). I must say that the ride comfort is really up a few notch compared to w211. There are so many buttons and feature that I need some help from all the experts here.

1) where can i find the button to tell me my average petrol consumption. In the past, W211 just shows on the instrument cluster.

2) I can't change the ambient light color. currently only orange.Is it an option to have blue and white?

3) Are the stock speakers easily spoilt? When i turn up the bass, it sounded "broken" like there is no bass. I change the fader and balance and all sounded broken.

Any bro change all speakers before? Any idea what is the price range be?

It will be ideal if any bros knows how to remove the speaker cover so I can actually see if the speaker coil is broken.

sorry if the first 2 question are not ICE related
