buzzing/whining sound coming from speakers in chevy tahoe / suburban / silverado 2007-14 

this applies to any chavy tahoe or similar models from 2007-2014 and some older models with similar options. the part I replaced is called "rear audio control unit" and u can find them on Amazon or Ebayat a better price. Also, I noticed I called the problematic clip RED, but I meant to say GREEN. I hope this helps somebody. Good luck!
