Hey Stogey -
Did you ever get an answer to your right speaker not working properly? I have just picked up an '07 Roadster with exactly this problem - stock Infinity AM/FM/CD Player in it. I have sound primarily only from the driver's side speakers. I have reviewed the vehicle owner's manual, and made adjustments to the balance, but when set at 9 for the righht side I have minimal sound coming out with none on the left. Set at 8 I have some semblance of stereo but the volume has to be set very high to hear both sides.
How can I change the settings to get proper stereo at a reasonable volume setting?
Your help is greatly appreciated.
