I noticed that you are using the telephone power connector as the source of your switched power. I used that connector as a power source to charge an iPod when I had a CDR-220 stock head unit. I also had an alternator whine, but only when I played music from the iPod.
When I wired my Pioneer deck, I used the power sources that were designed for the stock head unit and I don't have a whine with any sound source.
I cannot be sure that the problem is coming from the phone connector, but I would try a different source for switched power as the first step. If you need the information for the stock head unit wiring, let me know and I will scan and post it.
Good luck.
