A subwoofer is a substantial part of a home theater system. Speakers deliver lower frequencies around 20 to 200 Hz. However, you can’t feel those sounds without a subwoofer. By installing a subwoofer, you can hear the bass, which will enhance your experience when listening to hip-hop music or when watching action flicks.

Subwoofers have a long lifespan depending on the quality of the device. High-end subwoofers from reliable brands usually have a longer lifespan than the rest.

Take note that when a subwoofer doesn’t work properly, it does not always mean you need to replace it right away. Sometimes the reason why it is not working as it should is quite simple and can have a remedy.

If your subwoofer is not working, below is a guide on how to troubleshoot subwoofers.

#1 Check the Wire Connections

Before getting started, make sure the theater is system is off and disconnect the cables to prevent electrocuting yourself.

Once the speaker system is off, including the subwoofer, start troubleshooting the latter by checking its wire connections. A loose connection or an unconnected wire is the common problem why subwoofers don’t work. If it is the issue, firmly connect the cables and plug correctly.

When plugging in the wires, make sure the inputs at the back are connected to the subwoofer output at the back of amplifiers.

#2 Look for Damaged Wires

What if the wires are connected? What should you do next?

The next step is to inspect the wires for defects. A worn, torn, and damaged wire affects the device’s performance. If some wires appear to be damaged, perform a quick test to find out whether the wires are still working or not. If the damage is irreparable, replace the defective wires.

#3 Inspect the Power Cable and Outlets

Secure the subwoofer plug into the wall socket, power strip, or surge protector. Sometimes a poorly connected plug is the reason why subwoofers don’t work. It prevents the flow of power to the equipment, which results in poor performance.

Make sure the “standby” LED glows in the subwoofer. It indicates that the power is flowing to the device. If not, follow the advice above.

#4 Check the Subwoofer System or Program

If the wire connections are secured, and there are no defective cables, go to the subwoofer’s menu system. Check the program of equipment, for you might have accidentally changed the settings.

Here is a piece of advice if your subwoofer offers a speaker size setting. Choose the smallest option first; the speaker size setting sometimes disrupts the signal flow of the system. For instance, if you set the equipment into a larger speaker size, the subwoofer might not receive a signal. Thus, make sure to revisit the manufacturer’s manual. You might find more details regarding this matter right there.

If the subwoofer still doesn’t work after all these steps, consider replacing it. You can look for premium subwoofers in the market through reliable online sources.
