Windshield Replacement Kills Speakers?

[Lejon]

I had my windshield replaced on my 2001 IS300 after it was cracked badly by a rock. Now, my speakers are not working. The stereo seems fine, because it is on and I can switch between radio, CD, etc.. but there's no sound coming out of the speakers.

The guy at the glass place says there's nothing that he did that would go anywhere near the speakers. He says he removed the glass from outside the car and only had to release somehting from under the hood but there's no speaker wires in the vicinity.

Can anyone offer any insight.

Thanks,

Joe
