Hi the experts

I Have 3 Questions :

1. Where is the Sound Amplifier (Bose) is located and how it looks like ( picture will help )
2. Does All the C-Class 240 2003 comes with the Amplifier Bose or it.s an Option ? ( mine is the classic version )
3.If I do not have it, How to install an aftermarket one ( a Video or link will help )

Thanks a lot

 

The Bose system was an option. If you have it, your speaker grilles will say Bose on them. This was a relatively rare option. It depends on whether or not the original owner ordered the car with the option or not. German car options generally aren't tied to trim levels.

Modifying the radio is relatively straightforward. You just need the adapter that changes the trim shape to accept a DIN unit.
