static/popping from speakers

[grider68]

Need some help all. I have an 07 Yukon with the Bose audio system. Anytime there is an audible indicator (turn signal, door ajar, low fuel, etc..) the speakers start making a loud static popping noise. This noise cancels out cancels out whatever kind of audible indicator that is trying to sound off. This issue isn't constant but happens about 95% of the time. It also does it while the radio is on. Any help would be greatly appreciated. Thanks in advance.

Factory HU or no?

Kinda funny, my work van, a '05 2500 Express, does the same thing but the opposite. I get static on my am channel sometimes that will go away the second I step on the brake pedal, or plug something into the cigarette lighter. Really strange. Something to do with grounding I think.

That would be grounding yes.

Yes it is all factory including the head unit. We have not had any electrical work done.

Sounds like it's the HU, that's where all those sounds come from.
