i got my pioneer navigation installed in my AUDI A4 2006. The Front and the Rear speakers are not working and the rear door speakers has very low volume. Once the front door speakers are working properly. I asked the guys and he says, once you install the after market radio you will the front and rear speakers. Is this true- i dont believe him. I think he is trying to rip me off.

if Someone can please explain what the problem is? and how to fix it.

Thanks a ton,

Can you please more clearly explain your issue? I don't think anyone can understand what you just wrote. Not trying to be an ass, but I have a 2006 A4 with a D3 (I just put in a X910 in a MK6 Golf last night,so I know WTF I'm doing) and will help you out here if I can.

did you ever get it figured out, im gettin x910 this week, and also have a 06 audi a4, non bose.
