Ensure the subwoofer has not been muted. Increase the volume level on the subwoofer. Ensure the speaker settings on the stereo system or TV have been configured properly to use the subwoofer. IMPORTANT: Certain speaker settings may disable the subwoofer.
Why is my subwoofer getting power but not working?
The most common cause of a subwoofer not working is the wiring or the connections of the subwoofer with the rest of the sound system. Leaks, breakage, twists, corrosion, loose connections and incorrect wiring are all quite common and can create problems with the subwoofer even if the amp has power.
How do you connect a headunit to a subwoofer?
A subwoofer and an amp run on a different voltage than your speakers and head unit. To compensate, connect a line out converter to your head unit by connecting the right channel and left channel in the line converter to the right channel and the left channel in the head unit with RCA cables.
Why does my amp have no output?
The speaker is completely blown. The output transformer is open or otherwise faulty. The speaker jack is not wired correctly. The speaker wiring has deteriorated, or the jacks have rusted to the extent that they can no longer make the proper connection.

How do I know if my subwoofer is blown with a multimeter?
Connect the multimeter’s probes to the positive and negative terminal of the subwoofer’s voice coil after setting it to the ohms setting, specifically in the 200 Ohms range. It is good if you get a reading between 1 and 4, if it shows no resistance, the subwoofer is probably blown.

Can an amp be too weak for speakers?
If you don’t have a powerful enough amplifier to reach the volume levels you want, you can damage the speakers by feeding them too much high-frequency energy by driving the amplifier into clipping. It’s the extra power in these harmonics that damages speakers.
