Audio Systems: dodge truck infinity system, infinity system, factory radio

Question
My front speakers stopped working. I switch the radio with another factory radio and the same thing happened. Some say radio some say power amp, some say speakers.

Answer
If the factory radio has hte same problem, I would vote for the speakers being bad.  If you know which wires int he harness are for the speakers, measure across the wires with an ohm meter.  You should read bwetween 3 and 6 ohms.  If you read infninity, the speaker is blown and needs to be replaced.
