Hi,

I have a 1995 C280 and started it up today, and upon turning on the radio I heard a loud pop coming from the the right rear area inside the cabin - I assume from one of the speakers, but when the antenna mast came up and the radio was on - the system sounded just like normal, but then as I was driving I heard a loud siren like noise from inside the cabin (kind of like hearing a police siren INSIDE my car) and I smelled a burned smell from the speaker grill on the driver's side door - I also felt like a got shocked inside the car espcially near my left leg (near the speaker than smells bad) and I then turned off the radio.

Just so all of you know, I had had a sub and amp installed in the trunk of the car, but I took out all of the wiring that was installed for the amp to make the sub work, and disconnected the wires going to the battery. Please help on this issue - I told my mechanic about it and he said I may have a short in the behind the head unit. Anyhow, what do you think is wrong, and how much of the car must be taken apart (isn't wiring inside the door panels- that must be a pain) or dismantled to accurately diagnose what is wrong with the radio/stereo system. Please help - I'm afriad to use my radio right now.

Thanks,
Troy

It sounds like you have a high output connected to the wrong place. You may want a tech to look at this. Smoke is a bad thing inside of a car.

Troy,

If I were you, I started by taking out the front speaker that caused the smell to see what got burnt. When you take it out, you should be able to see whether it is the wire or a speaker's condensator that was shorted.
When you remove the grating in front of the speaker, you can take out the speaker and unplug the connector easily.


three screws and one connector is all there is

After you found out what was burnt, take out the head unit to see what is wrong (maybe one of the speaker wires got grounded or powered by accident).

greetingz,
