Try unplugging your antenna or running a separate positive and negative to your head unit.

Tried that with mine didn't work, the dealer even replaced the deck to see if that was the problem but that didn't work either

I had the same issue on my 2014 T22. The feedback was very annoying, after working with the dealer they found the issue.
It turned out to be a loose/faulty y splitter that came off the amp heading to the head unit.
They found which speaker was making the noise and the y splitter and swapped it.

Have had no issues since. Hope that helps

How many batteries? Are all amps grounded on the same battery?

mine did the same but mine was a loose rca which you have checked, hope you find your problem

I think I have the same issue. It's just the tower speakers. It was initially just the two on the two on the right, now it is two on the right and one on the left too. Is this the buzzing you get when the volume is at around 20 but nothing is actually playing?

Swapped out the rca cables and it helped a little but has not went away. Going to try the extra ground tithe deck and see if that helps. Noticed the ballast pumps add even more feed back. On the plus side the water and surfing was great for the 4th

are you running the stock Sony deck? If so add a ZLD...

Yes stock Sony. ZLD?

Exile zld equilizer. It increases preamp line voltage. Bought mine today and no more wine
