I have a 2000 Tahoe 5.7 4X4 that makes a whining sound from the speakers whenever I accelerate. I'm thinking its either a bad battery connection or a ground somewhere. The rotor, cap, plugs, and wires are all fairly new (1-2 yrs. old) Does anyone know how many grounds there are and where to get started at? Thanks, Skip

You have Ground Loop issue. See

OR go buy an inline noise reducer for about $10 and install. It will clear things up.
