Hello everyone!

This problem has been bothering me for a while. It started a while ago that the right side speakers turn on and off. Here is the funny thing...When they are not functioning and I turn my radio volume down, I can hear a slight high range noise coming from them. When they actually function that noise is not there when the volume gets all the way turned down.

Here is how they start working again. Most times when I run over little wave in the street they turn on or when I turn the volume up real loud they usually turn on as well which makes me think it has to do with "vibrations".
Where should I start to locate the problem? Do you think there's a short in the wiring? Could it be the harness behind the aftermarket radio? Or do you think it's actually the wiring behind the speaker covers?

I'd be happy for any input on this and where to start. I'm not a specialist when it comes to wiring, I put the aftermarket harness together as described on this forum and it worked fine for a while until recently this issue came along.

Thanks guys!

Nick
