I just installed all new aftermarket speakers in my Kia. After I finished testing them with the last door panel off, they all worked. After replacing the door panel that was off I checked again and none came on. The radio was on and functional but no sound at all. What might be the problem?
Just a guess, but you may have bumped the wiring as you were placing the door pad. Best option is to remove the pad again and check everything, make sure there is plenty of slack in the wiring in case it is being pulled tight. Or it could be earthing out.
