What Causes a Subwoofer to Stop Working?

Short circuit is the most common cause of subwoofer failure. When a short circuit occurs in the wires that provide the signal, it prevents the signal from reaching the subwoofer. Similarly, a short circuit in the subwoofer terminals will also prevent electrical current and signal from reaching the subwoofer. Short circuit is a reliable way to stop any subwoofer. In case of emergency, it is important to prevent electrical signals from passing to the subwoofer.

A short circuit also restricts electricity, and current cannot reach the subwoofer. The electromagnet cannot produce the necessary energy that it has in the wires for a short circuit, and this energy will not be able to drive the cone. To check for any issues, inspect all cables and connection points that go to the amplifiers, receivers, or speakers. Make sure that all cables are properly connected and plugged in at the correct points. Check the power outlets, power cord, and fuse.

Most subwoofers have a standby LED that lights up to indicate active power. If it is not turned on, ensure that the subwoofer is properly plugged into a wall outlet, surge protector, or power strip. If the pins of a plug slide halfway, it is often enough to prevent the flow of energy from gently bending them so that the cable stays connected after you release it. Additionally, check all associated switches (i.e. those on walls, power strips, etc.) If the subwoofer still won't turn on, try plugging it into a different outlet that you know is working properly.
