High pitch ringing even with no HU on. Bad ground? Amp failure? So I have a 98 Z with the Monsoon amp and over a year ago bought Kee Audio's level 2.5 package. The past month or so, when I turn the head unit on- even before music plays, there is a high pitch ringing that instantly starts and persists along with the music. Due to this and losing my phone whose Spotify app I used to play through the bluetooth head unit (Pioneer) I pretty much stopped trying to listen to music.
I recently got another phone and upon turning on the head unit, not only was the high pitch ringing back, I could barely hear the music even when turning up the receiver way past where I needed for the music to be loud previously.
I did some searching on this and most seem to say the ringing can be a bad ground. Is there any particular place to look? I am not familiar with audio equipment. And is the too quiet music also related to something loose or has the amp gone to ****?
