No sound out of any speakers. Stereo turns on but no sound. I was changing the subwoofer, when stopped working.

Re-check ALL the wiring you did. You either had something disconnect, or shorted a wire out or the speakers are too powerful for the stereo in the car.

Thanx. I did short something I believe. The metal from subwoofer touched metal when I was putting it in and I forgot about disconnecting the battery. What do you suggest? I can't find any fuse labeled radio or anything that I understand.

Don't worry about the fuse labels, just get an inexpensive fuse tester at any auto parts store or even walmart, and check all of them.

No sound come from any speaker
