I just installed my new Pioneer head unit today and it being my first time doing this i wasnt sure if i was doing it right. After I was done I noticed that I must have done something right cause i was hearing music. Now the problem is I only hear music when the plastic connector with all the wires is only pushed in halfway to the head unit. When its pushed in all the way,there's power to the unit, but no sound...
Any thoughts to something I might have done wrong or should double check??

 

Recheck your wiring. Sounds like you have something connected wrong to me.
