    Pioneer Premier DEH-P840MP, wiring harness to Subaru.
    No electrical problems on the car but a high pitch sound gets louder/higher with my RPMs. Coming out the back is one RCA in from the XM radio, radio antenna and wire harness.

    Ideas?
    In writing this I will try to unplug the XM to see if thats it but it will do it with radio, XM and CD.

    Thanks! :)
