No sound coming from my speakers

[bholm6]

So I changed all four door speakers the other day with some Pioneer 3 way 300 watt max to go along with my Pioneer head until that I've had installed for a while now. I had no problems until today when I had the volume @2/3 max and I lost all sound. Turned off the radio and when it first comes on there is sound for a split second and then its gone again. I have checked the speakers, head unit and fuses. No sound no matter what input. I'm at a loss for what it could be. Any ideas?

UPDATE: So I did some more searching a found out that if one of the speaker wires is pinched it will ground out, resulting in no audio at all. Sure enough after I removed the door panels I found multiple wires pinched. Apparently the extra vibrations caused the wires to get lodged between the speaker and the door itself. I simply rerouted the wired and wrapped them with some extra insulation to prevent any further issues.
