Help! Car Audio won't work with my system!

Hey everyone, I have a problem. Today, while listening to a CD, I hit a bump and the audio seemed to all of a sudden shut off. However, the CD player itself did not shut off. Upon inspection of the display on the face plate, the CD was still playing, as the track listing and timing of the song were still there and still going. I removed the CD and tried playing the radio, but to no avail, no sound there either. I am really confused. I looked at most of the wiring and everything seems to be in check. Everything about the stereo is normal, it's just that it emits no sound. I really need help with this, I don't know a whole lot about stereos but any information is thoroughly appreciated and I tried to explain the problem as best as I could. The stereo is a Pioneer DEH-P75DH if that is a question at all. Thanks so much!

is that the one with the dolphins birds and formula one cars.....

its gotta be some loose wires.....thats the most likely cause

Well first off you need to be more specific with what you have. Is it just the CD player or do you have any aftermarket amps. Second did you car have the factory Bose system?

i dont think he has any amps but its 99% a wire failure.....somewhere....
