Alt whine solved
I asked a tech at work what the best way to get rid of ground loops/alternator whine, he suggested buying a noise filter. First I tried on my constant batt into radio, it seemed to be better, but on second thought, it wasn't. So a few days later I chopped it off and tried on my ACC wire, definitely not better. Today I was going through some old wire scrap bins and found a chopped harness with a noise filter on one of the + wires. Having read that sometimes you may need to filter all 12v sources into radio, I swapped the $15 filter back to my constant wire and added the freebee filter to my ACC wire. Under heavy acceleration I get absolutely no hum/whine through my tweeters.
Lesson learned, noise filters can work, if you have enough of them
