Audio Whine - rear door tweeters only

Cross post to the audio section, but it is on my D2.

Recently installed a Chinese made 10" touchscreen, used the Schosche SLC4 (https://www.scosche.com/car-stereo-output-converter)adapter and two pac SNi-1 RCA noise filters (https://catalog.pac-audio.com/catalo...erfacing/sni-1). Thoroughly grounded the head unit caseing/housing to the dash metal structure with a separate ground wire.

I have a very annoying alternator whine (increases volume and frequency with engine speed) in the rear door tweeters only. Anyone ever run in to this and have a fix?

Do you have anything like this plugged into the cigarette lighter? If so, unplug it and see if the whine goes away.

I wish it was that easy, yes of course I use one of those but unfortunately unplugging that makes no difference. I guess I will have to start installing choke coils in the system.
