I am new to the forum and hopefully this is in the right place? I have totally changed out the audio system I'm my 2012 SG. when I turn the ignition to the on position, the headhunt comes on and displays the time. I have NOT turned on the audio system yet. Just the power to the headhunt allows the time to display. Wait about 2 seconds and now a noticeable hiss comes from the speakers. Volume does not change anything as the audio is not on. When I turn it on every rocks fine. Why would the speakers be hissing when the audio is NOT turned on yet?
