Hello. I decided to check the wiring for the speakers today as the front passenger side tweeter doesn't work, passenger rear speaker and tweeter weren't working. Took the door cards off and couldn't see any disconnected wires or breaks. Also looked at the back of the stereo and could not see any lose wires. Tried other speakers on the connectors and they didn't work also. Does anyone know what could be causing the speakers to not work?
