I've got a 2002 Tahoe 4wd. I think I've got a ground wire loose somewhere. The speakers have a bit of a crackle even with a cd, my headlights and interior lights have slight flickering thing going and the blower for the a/c and heater seems to lose some power for a second or two after accellerating. Is there a particular ground wire or wires that are known for coming loose? Where should I start looking for a solution? Thanks for the help!

Start at the battery and the engine, chassis & body. Clean them with a fine stainless brush and use dielectric silicone on the terminals.
