Speakers not working sometimes on right side of car?
 

I have an s500 w140 1995.. basically when I am listening to radio the right side speaker isn't working at time and when I go over a bump etc., it starts working for a few seconds and stops.. I think its a loose connection.. Where would I look to find this 'loose connection'? Or is it something else?

I am guessing the trunk..but where in the trunk..

Thanks:)

Two possibilities that I can think of: Wiring between the body and the door can get brittle and crack. Or it could be a poor connection on the speakers.

In the trunk
 

My '93 W140 does the same thing. I found that the cable to the CD changer was not making a good connection. I reached under the CD changer in the trunk and jiggled the cable and it worked OK for a while. Every one in a while I have to do this. At some point I'll have to do a proper diagnosis and repair but this is what is working for me at this time. YMMV.

Thanks.ill give it a try..

Do you have factory amps in your car? If yours are like mine, there are 2 amps in the trunk on the right side. One amp/connector is for left side, the other for the right. Check that connection.

yes they are factory..ill check that out too..thanks
