Power Supply Issues

In case your subwoofer does not receive enough power supply to get operated, then you might get an alert. An erratic power supply or low voltage can pose a significant problem in the smooth functioning of your devices.

Also, the voltage coming to your device must not fluctuate. 

Solution: Get a Stabilizer or Voltage Regulator

To regulate that, you have to have a stabilizer or voltage regulator. This ensures that the power is supplied correctly and controlled.

When picking out a servo voltage stabilizer, it’s important to think about a few things: how much power your devices need, what range of voltages they can handle, how quickly the stabilizer reacts, how efficient it is, and what safety features it has. 

For example, if you’re using a subwoofer that can take up to 100 watts of power, you’d probably want a stabilizer that’s at least 1.2 kilovolt-amps (kVA) or higher.

An issue with Bluetooth Pairing

You might forget to connect the devices via Bluetooth. Without a proper pairing, your subwoofer won’t work properly. 

Solution: Pair the Bluetooth Properly

To establish a perfect connection, you must turn on the Bluetooth of your soundbar and your device; thereby, you are supposed to pair them with one another.

Having done that would resolve your issue instantly without any trouble. Pairing the Bluetooth is easy, and you can do that momentarily.

Connectivity Problems

Connectivity Problems arise due to poor cable quality or a mismanaged setup. If the wire you use for connecting your soundbar and subwoofer is not reliable or not good in quality, you are likely to get an alert from your soundbar.

Solution: Replace the Cable

Use a fine and thick HDMI ARC cable. Not only would it ensure a proper connection, but it would also prevent all kinds of short circuits in the wiring.

While you set the HDMI ARC cable make sure to do the following

  • Check the compatibility of the cable
  • Connect the cable properly and configure the settings
  • Check the audio output

Faulty Setting of the Subwoofer

If your subwoofer has already sustained issues with its sound bass, or volume level, it will create a problem in its working. 

Get a constant alert from your soundbar to check your subwoofer. 

It could be because one of your devices is faulty, or otherwise, there could be an issue with the wiring. Try managing that to get it back to work.

Solution: Diagnose the Subwoofer Setting Properly

To resist that, you need to ensure that your subwoofer functions correctly and there are no underlying issues in the system.

Make sure to plug in the subwoofer, turn it on, and adjust the volume to the right level. Double-check that the subwoofer is properly connected to your audio device and that nothing is blocking the connection.

Large Distance Between the Soundbar and the Subwoofer

When your soundbar and subwoofers are placed far apart, there lie several hindrances between the two devices which obstruct the sound signals from passing directly from one end to the other.

This results in the disturbed functioning of both of your devices.

Solution: Set the Proper Distance between the Soundbar and the Subwoofer

If you have your soundbar and subwoofer kept at a distance, try to replace it, and then the problem might be solved.

To get the best sound quality, keep the subwoofer less than 9.8 inches (0.25 meters) away from the main unit of your soundbar. Though Bluetooth can connect up to 33 feet (10 meters) away, it’s smarter to keep the subwoofer and soundbar close to each other to prevent any wireless problems or audio quality glitches.
