How to fix a subwoofer popping when turned on?

1. Disable The Auto On Setting

The auto-on feature is used to turn on the subwoofer automatically when it detects an input signal. This auto-on mode reduces power consumption and, in turn, decreases internal heating.

But some issues occur in the auto-on circuitry that leads to this popping sound.

If your subwoofer is in auto-on mode, then chances are there for this popping sound. So the solution for this is to switch to power mode from auto-on.

2. Turn off your AV receiver and amplifier

Your AV receiver or amp that is connected to your subwoofer can send unwanted signals to your subwoofer. So disconnect the RCA cable from the receiver or the amp and then look if the problem is solved. If the popping sound stops, then the receiver or amp might be the cause of the problem. Also, it is recommended to connect your subwoofer with a different signal source and check whether the issue repeats it.

3. FIX the Wireless Subwoofer Interference

Wireless interference occurs when the signals coincide and negatively affect each other and disrupt or weaken the Wifi signal. This might be due to the signals that are emitted by the different devices in your house.

To fix this problem, you can move the subwoofer to a different place and see whether the popping sound stops. Or move your Wifi device to your different place. You can also use a Wifi shield to shield your sub from surrounding devices.

4. Receiver consumes too much power

If your receiver consumes too much power, then your speakers connected via it also draw high power. Over time, this causes the popping sound issue.  So to fix this issue, buy a good external amplifier that can handle the power correctly.


You don’t need to run every time to the manufacturer or shopkeeper to fix small technical issues like popping. Most of the time, something minor like the delay of a signal could be the reason for the popping of your subwoofer that can be fixed on your own.
