Not sure what to do. I have an 06 c class coupe.with navigation system. Radio and cds play but get no sound! Any ideas?

 

might be crimped/pinched wire. best thing to do is look at the speakers and see if they're blown or wire grounding out.

 

I gave my car to local garage to fix minor front end damage but came back like this. They r not open till monday!! Is it likely all speaker s need checking. Might be nothing but steering feels heavy too. Might.be the fact ive been driving a micra for 2weeks.weird

 

i call it's a shorting issue in the factory amplifier. check fuses and test power leading up to the factory amplifier.

 

where is the factory amp?

 

in the trunk
