Rear Speaker Issues

OK, so my rear speakers don't work. I yanked the ones out of a car that I know work, rigged up a plug and poof, still no worky. I thought I remembered seeing a diagram for the PDC of a 99, but I can't find it now, I've searched here and through Google. Any help.

Check with a voltmeter to make sure you are getting power to the speakers. If you are not getting power, pull your head unit and check the power at the harness for the rear speakers. There are color codes all over the internet for the radio.
