Pontiac Sunfire Speakers stp working?

[Tyler]

I was putting new 6x9s in my car just earlier. I put the first one in and tested it and it worked great, then i went to wire the second one in and none of the speakers would work. I checked the fuses, wires and even unplugged the positive terminal from the battery to reset everything but still, no power.... any ideas of what i did wrong?

Do you have an aftermarket head unit? If so, check the wiring harness to see if wires came untied, or were wired incorrectly. Other than that, I would be stumped.
