DOor speaker help!!

My buddy replaced a window motor on the driver side of my SS Camaro yesterday. It has the Monsoon speaker and it was working fine. Now the speaker isnt working at all and i opened up the door panel and it all looks like its plugged in fine. What could have caused this !?

Could be coincidence that it died or the wire could be cut. Have you removed the door panel again to check the wire?

there are two wires to be plugged in..
