problem with alternator whine after new h/u

[Ant R1]

I installed my kenwood kdc x794 in my 05 yukon with factory bose system so I had to use the metra gmos 04 adapter to keep chimes and factory amp untill I get money go upgrade all components, also I installed the metra aswc and now when the radio is on but turned all the way down I get some alternator whine out of only one speaker and I never had the whine before the gmos04.... I've took it apart twice and re wired and still can't get rid of it.......help please
