After putting in a new deck and a sirius reciever I have noticed that there is always a high pitch turbo like whine coming from the speakers. The noise gets a little louder and higher pitch when I increase the throttle, the noise is consistent to what my RPMs are. The higher the RPMs the louder/higher pitch it is. When I turn up the volume on my deck the noise also gets higher, the noise goes down when I turn the volume down also. Anyone have any idea what it could be? Before I had a sony deck and there was nothing like this, after putting in an alpine deck and sirius reciever I started healing the noise.
