Well, I've had this noise in my right comps for about a month. It's been driving me nuts. The audio shop and I couldn't figure it out. It wasn't the amp or RCAs. I took apart the center console and dash to get to the back of the HU. I was maybe thinking it was this little box for the power source since I have a dead head. I relocate it to underneath the seat heater switches and the noise is gone.

Well, I put everything back and the noise comes back. I soon realized that the noise comes back when I have my cell phone charger in the center console outlet.

The easy fix is to just leave it unplugged. Anybody else ran into this problem? Any way to fix it? It happens only in Acc II, when power feeds to that 2nd outlet. Is it possible that certain charger is causing the problem?

 

Is it an OEM charger? Maybe it's just a cheap/broken charger. Borrow a charger from a friend or something and test it out. See if it happens with all car phone charges or just yours.
