2006 RT Radio issues

Hey gang my radio has been breaking up.

It seems like a bad connection to the speakers but I can't find any loose connections. It's on all functions Radio, CD and iPod. so its not a reception issue. It doesn't matter if I'm moving or stopped or if the motor is running or not.

I noticed it started a month or so ago but was intermittent so I thought i had an issue with my iPod or cable but now it's there with all audio functions.

Any suggestions or others with same issues?
