It is crucial to determine which model of audio drivers are being tested. Then, disconnect the outside speakers from the two terminals on the back of the amplifier. Put a DC ohm meter across the terminals. If the reading is higher than the listed value, then one or more of the drivers could be open, or a connection is corroded. If lower, one or more drivers or the wiring may be shorted. | It is crucial to determine which model of audio drivers are being tested.
