Im trying to install a Dual Cd770 head unit in a 2000 sunfire. It turns on,plays cd but theres no sound, ive tried reversing the polarity to the speakers cant figure it out, any help would be great

Is there a Internal amplifier? (hook up the blue wire to the harness, and make sure its the remote wire, not radio one)

blue wire(remote) was connected to the power antenna wire from the car harness..right??

No. The Sunfire does not have a power antenna. This wire does not need ot be hooked up unless it is going ot be used to turn something on such as an external amplifier.
