Is there a member who is fluent with car audio electronics? I'm having a problem with my radio, static and poor AM-FM reception. I know the radio is good because I can plug-in an antenna into the back of it and it works. The problem is trying to determine if the problem lies inside the antenna cable as it journies to the trunk. How can I use a multimeter to determine if there is a break along the way or if my powered antenna booster/amplifier is defective. The last item is not standard issue. Any tips for me? I would like to test the cable to see if there is resistance or no flow if you will and not sure how to do this. Reasoning, if the cable is OK than the antenna amp has gone bad, Thanks Steve
