Hoping someone on here can help me with an issue that started up today while we were out in our new to us C6. There is a buzzing noise in driver side door speaker and everytime you push any button on the information center (DIC) or turn the radio on or off and when you turn the volume all the down the dash speaker pops. We turned the radio off and while driving down the road the speaker would pop for no reason. Another thing we noticed when we go home and parked the car when i opened the door to get out i noticed the door speaker was making a buzzing noise and after i shut the door and the power turned off the speaker popped yet again
Pls any information is appreciated

I saw a post on this a few months ago. I can't find it. I believe that the issue is with either the amp in the speaker or a relay that effects that amp. My 07 has been doing that off an on for a couple years. Do I search and see if you can find that post.
