Hooked every thing up right and the unit has power and does all the functions just no sound at all. And the speakers worked with the factory stereo unit.
Possible scenerio's with the little info you gave.
1.You have a bad speaker thats blown or the wires are touching the chassis of your car.
2. You have a factory amp and you need to connect the blue wire to the amp turn on wire. And if it still doesnt work then you have to rewire it complete or maybe have to get a special car amplifier compatible harness so your aftermarket works with your amplified system in your car.
3. In certain Ford cars they crisscrossed the back speaker wires. To test this unplug your harness from the radio. VERY IMPORTANT( splice these colors of wires in the middle enough so you can use a 9volt small rectangular battery to make the speakers you want to test pop(harmless))
1. green = back left + speaker
2. green/black = back left - speaker
3. purple = back right + speaker
4. purple/black = back right - speaker
test green speaker wires first touch battery to the + and - and the speaker should pop if not you have already discovered the problem. Know this time pop the green + and the purple/black - on the 9volt battery if the speakers pop you have found the solution.
Just criss cross the the negatives of the back speakers. From the radio harness end attach green to green, purple to purple, green/black to purple/black and last purple/black to green/black. And all your speakers should work again.
Dont ask me why late Ford Models crisscrossed their speaker wires. They just did.
