Amp Service Bulletin So just a FYI. I took my 08 GXP in for it's oil change and I told them the center speaker was blown so when the dealership went to order a new one they came back and told me GM sent out a service bulletin saying to replace the amp first if the center speaker is poppin, buzzin, hissin, cracklin, ect..... So they ordered me a new amp.

its not hard to tell if your center speaker is shot (3.5 inch) popping,buzzing. I had mine go in my 07...took me a week of above average sound levels. Ive since replaced all my speakers except the rears with aftermarket (Treo) ones. Saving up for a 18 inch treo sub! hahahah

Already had mine replaced not long after I got the car in 06 because of a hiss, I was told then of the TSB. Didn't help much, just a little. Thats bad to hawk the BOSE system as being their best and then having a TSB issued.

thats a bunch of bullshit....they replaced my battery even though it was my fault it went bad...my aftermarket head unit made the onstar search all the time and killed it.
