Re: 2008 GMC Envoy speaker static
Looking at the manual (p. 3-70), one thing you could adjust to account for this static is to decrease the treble. Aside from this, I hope you're able to get some great technical feedback from the other forum members, and if you should decide to visit your dealership to get this looked into be sure to let me know.
