Popping Noise In My Speakers When I Use Electrical Stuff

[johnsonjf]

Hey guys thanks for taking a look at my post. I have a 2007 NBS Silverado 1500 ext cab with a little over 2,000 miles on it. I can't remember if it has been happening since the beginning or just really early in my ownership of the truck but when I am connected through the AUX audop port on the stereo and I have the stereo turned up about 50% or more, I will hear a popping noise through the speakers when I press the brake pedal as well as when I roll up or roll down my windows. I have not modified the audio system in any way except for that I have my XM hooked up through the AUX port with a gold-plated 3.5" connection wire.

 

If anyone has any suggestions they would be greatly appreciated.
