Re: Defective Amplifier
I had a similar problem. The 6 door speakers weren't working (2 per front door + 1 per rear door). Only the front center, sub, and 2 rear column were working. I didn't notice at first because the center front speaker is nice and combined with the 2 rear column speakers, you do hear sound from both sides. I recommend playing with the fade and balance then getting out of the vehicle so you can get close to each speaker to verify sound. Through this great forum I found TSBs. I searched them and found 08-018-11a. I printed and brought to the dealer with me. Of course the day of my service appt, they all start working. (go figure)! I told the service manager about the tsb & he said it was unlikely. Then since the speakers were working at the moment they said they couldn't find anything but checked wiring etc. A week later...same as before, speakers not working again. I bring it back and bring up the tsb to another tech. They still said they didn't think that was it. Luckily speakers stayed not working for this appt. Day later, I get a call saying they had to order a new amp. Now I have to wait a week for shipping and spend another day at the dealership for install. Oh one other thing I noticed was an occasional popping noise from speakers.
