I have a 2003 Chevy Silverado Z-71. Within the past week-10 days, I've noticed that there is a whine (sounds like high pitched white noise) coming through my speakers whenever I am driving and the pitch gets higher whenver I accelerate. If my radio is off, there is no noise. I have the Bose speakers in my truck, all stock, no aftermarket. Can someone help me to get rid of the noise!!!
