Front driver speaker not working. The only thing I have to test it is a cheap lil 12v tester (1 with light in handle of a screw driver). Is it possible to test with this. When I ground the tester and touch each terminal separately the light does come on albeit a Kim flickery but never the less the light is on. I have a feeling this is not a viable way to test car speakers. Any suggestions
Also, you can get some speaker wire directly from the radio to the speaker - if it works fine one possibility is the speaker wiring is damaged in the joint between car body and door.
