You can only hear the speaker whine from volume 0-2 and then the music goes over it. It still annoying. It is more hearable in the back coaxials. It is not altrnaor whine because it does not go up and down with rpms. It sounds like a higher pitch tone is being played through the speaker along with some static (u can only hear the static if u put ur ear right up to the speaker) s it a bad ground or something?
-I did sand the grounding point
-Sometimes the static goes up and down in volume randomly when the volume is at 0. Please don't say my amp went out already.
-I set the gains with a dmm.
