I have an annoying very LOUD pop sound!

[bearzilla333]

Ever since last summer, when i turn my truck on all 8 speakers POP so dam loud. when i change radio stations it make a very annoying pop sound. It also happens when i shut off the truck too. It will pop too when I change from listening to the cd to radio or vice versa. I thought it was a ground problem, I checked throughly with both amps they seem fine.I also do have a very low sounding hum when the truck is running. I thinking maybe the head units ground might be messed up? any suggestions would be great thank you.
