Howdy,

I have a 1996 C220 with the Bose system. Over the past few months, I have noticed a scratchiness in the sound from the right hand side speakers (seemingly the door speaker). Initially, I thought I had a blwn speaker, but after reading numerous posts, both here and elsewhere, I'm wondering in it is not the amplifier giving up the ghost. Is there a way to check/test the amp? Also, would anyone have any other suggestions as to other problems that may be causing the distortion? By the way, the LCD on the head unit is beginning to go as well, for what it's worth.

Thanks in advance!

(if you've seen this post on other forums, please forgive me. I'm only trying to research the problem as throughly as possible.)

 

the bose amplifiers was made with bad quality capacitorscold weather affects this unit
the problem is that the capacitors are damage and they are leaking acid on the board
this boar needs to be clean and the capactors replace
