Why is my Harman Kardon subwoofer not working?
Many Harman subs have an On/Off switch independent of the signal relay. If everything is connected properly and the receiver is sending the LFE signal to the sub, you may need service. If there is no light at all, you may have a blown internal fuse or other nonuser-serviceable issue related to the amplifier.
