I have an '08 V6 mustang and anytime i plug in my zune or ipod into the port under the center arm rest and put the stereo on "line in" i can only hear out of one speaker, the drivers side front speaker, i even checked my balance and fade and both are in the center. please help i want to know how to make it so i can listen to my zune on all the speakers

 

Are you using a 1/8" audio plug? If so, check your plug/cable, it may not be all the way in or may need to be replaced. You can check it by plugging in to one of the inputs on your home system.

 

And using a stereo, not mono cable. If you are, and your device is outputting in stereo then you might have an open in the cable fron the jack to the stereo unit or a loose connector.
