Probably rf interference from a plug/coil wire. On second thought bad wires usually make a ticking noise as the interference hits with each firing of the cylinder so maybe it's yer alternator. Check things like grounds on all accessories. just guessing here

Re: whistle in radio? (BobMachus)
Aha! One I can answer!
Most of the time when you hear a whistle coming from your speakers, when your stereo is on, it's from an improper ground wire in the stereo's circuit. When I did installs and put in amps and etc., the "whine" (which is actually the technical term), which rises and falls with your rpm, is alternator whine. The first place to check for an improper ground is near the head unit- your radio. If you have amps- (all bose), the loose ground could be near the amp itself. If you don't find it there, you'll have to root around under your hood- and hope it's obvious, it could be a bad condenser at the alternator, or even just a corroded wire here or there.
I'd probably try and do some recall first that would cause a ground wire to come loose, or become corroded. Did you dump beer on the carpet? (hopefully before you drank it, and not after- yes it's happened :U ) Did you install a new amp? A new head unit? A cb? Did you tear open your dash for anything? Even vacuuming vigorously could do it. Good luck- hope you find it! Take it easy- John
