My speakers freek out ocassionally seems to do it around 60mph. I can vary my speed and make it go away.
I'm guessing something to do with the transmission at that speed is causeing somekind of electronic interference.
I does it with the FM radio or the CD so I know it's not radio interference only.

 

I had the latest flash AV and no more speakers freeking out.

 

I have a buddy with an 08 Powerwagon. He has the upgrade stereo, but not the REC. He got a letter from Dodge asking him to come in and get the front door speakers replaced. His speakers had problems with high levels of bass causing distortion.

RiverRunner.

 

The speakers could definatly do better in the base department. My speakers were squealing didn't seem to matter on the base level.

 

Had both my front speakers replaced.

 

Well it's done it again. Now I'll have to take it in.
