I bought a 96 SL 500 yesterday and the radio worked okay all the way home (4 hours).

Today it has a lot of distortion out of the right speakers.

It was much warmer today than yesterday

anyone have any ideas if this is a radio problem or some other amplifier?

Is there a way to figure this out without swapping out/ replacing pieces?

Thanks
Ray

My 1995 SL 320 with the Bose system has all the classic symptoms --crackling,no bass,low volume,1 speaker not working,ect.So I printed off the door removal photos and went to town.MB wants about $1300 buy just the speakers,no labor.I am sending mine back to Bose for repair or relacement.If you want to keep the Bose system,you really have to do this every 7-9 years.Takes about 1-1/2 hours to get the speakers out and replace them.
