Do you get the noise while using all of the different settings? Radio, CD, AUX?

Sounds suspiciously similar to a "ground loop" issue, which can be a nightmare to track down.....

Saying it is worse with Bluetooth, that is the exact opposite of what I was expecting. I had to install a ground loop isolater on my '06 model, since it only has a AUX cable port. It fully eliminated by engine noise coming through the stereo.

Your issue has me baffled if it gets WORSE using a wireless signal. Beyond my knowledge there.

I guess I'd start by making sure the grounds for the amp and the headunit are good and work from there.
