Question about Proficient S12 Subwoofer
If there is power to the woofer then a signal input must power the woofer to work. So feed a test signal or a audio siignal from a DVD and if there is no output then the AMPLIFIER section had faults.
Unless the sealed unit is opened it cannot be tested to confirm if the output , the input to the AMP or the power supply has failed.
Check if there is power to the output section to confirm.
