I have an '10 cayenne and I have a problem where when I hit a bump I get a very annoying high pitch noise that comes out of the passengers speakers the noise does not go away until I either hit another bump hard enough or until I turn off the car and let it sit for awhile. I took my car the the deal to fix the problem about 6 months ago and they fixed it and it's back!! What can I do what is causing the problem clearly it's a loose wire or poor connection but idk where to start looking to fix and I don't want to take my car to the stealership and pay out the *** please help

 

I have some weird noises coming out of my wife's speerkers too on her 2004. The first problem and time was water in the Sapir tire location were the sub amp is . Now it's a clicking sound. That comes out of the speerkers wether the radio is on or not.

 

I had the issue with water in the spare tire well too. The drain tube from my rear A/C unit had come off. It shorted out the amp on the sub which is on the bottom. I bought a used one and swapped parts.

Not sure about a ticking noise though. Even with the stereo off? That sounds like a definite short somewhere.

 

Check the rear amp! Seen it more than a few times. If shorted or dying, it'll act up as described.

 

I have a 2010 Porsche Cayenne and I have the same speaker noise problem like what Joe described above. Any one has any solution to his hellish problem? Many thanks.

 

I second checking the rear amplifier.
