2008 Grand Prix GXP 5.3L



I recently bought a used '08 GXP and my center speaker is buzzing also. What are the chances of Monsoon or Pontiac fixing it out of warranty as a factory defect? I really hoped it was something trapped in there.:th_depressed:
 
i have an 08 and mine buzzes too, its quite annoying when you turn up the volume, combined with all the dash noises its like a symphony of crappy noises.
 
ask your dealer, if you bought it from a GM dealer, they should at least try and help you. You just made them a bunch of money. It never hurts to ask.
 


I have a 08 gp gxp. Center speaker sound slightly blown (popping). But i'm getting buzzing behind dash constantly sounds like a noisy harddrive from a computer. send some replys. i'm sure many gp gxp owners have the same problem, its driving me out of my mind.
