I have noticed an increasing whistle while driving. Its quiet enough that I don't hear it with the radio on, but off, it may as well be deafening.

My SS did the exact same thing, but intermittent, it was loose hoses on the HVAC controls. I thought ours were digital, but I could be wrong.

Is their something else that could cause a steady whistle in the cabin?

My car is 100% stock

That's actually what it is. right after I posted this I took a buddy of mine for a ride and he happened to hear the whistle over the music, he said its a grounded loop, I turned the stereo off and the sound went away, turned it on and it came back. the reason the sound follows the RPMS is because of alternator voltage.

I get the feeling it has to do with having my ipod, hooked up to the AUX port, and the power from the Cig lighter, one isn't insulated well enough
