I'm having a problem with the sound system in my vehicle. From time to time, I am getting a high pitched buzz from my left rear speaker (even with the volume all the way down). As well as bad sound quality from that speaker when I don't notice the buzz. I have swapped the rear speakers and still have the same problem on the same side, so it's not a speaker issue. I've checked all the connections. Could my back amp be dying? Would that explain the high pitched buzz?
Like I suspected, my rear amp was the problem.
