Your car’s subwoofer is intended to improve the quality of your music, not to transform it into a cacophony of distorted bass, whines, and noises. If the sound emanating from your once-booming subwoofer now resembles that of a malfunctioning automaton, there is no need to worry.
This article will assist you in diagnosing the issue and give a hint about what to do if your car subwoofer is making noise when turned on. I’ve put together an easy-to-follow guide that can help you determine the problem and how to fix it.

Why Does A Subwoofer Make A Humming Noise When Turned On?
It is likely a hum loop and not the result of a defective subwoofer. Ground loops and other external factors are frequently straightforward to resolve.
There are three potential causes of subwoofer's humming noise, and the manner in which your subwoofer produces this noise is a significant indicator: Is the disturbance extremely low and does not increase in volume? Is it perceptible and contingent upon the volume? Alternatively, is it perceptible without regard to volume? Each of these three forms of interference has an explanation.
1. The subwoofer is likely to be the cause only in the initial scenario. The power supply may produce noise due to its malfunction.
2. In the second scenario, the noise may be caused by an unfavorably located subwoofer cable or mains cable or by a disturbance in the mains. This is a result of electromagnetic interference signals that influence the subwoofer to varying degrees, contingent upon the power or volume.
3. The issue in the third scenario is highly likely a humming loop that is the result of resistors from the power outlet to the source device to the subwoofer, resulting in a deafening hum at the end.
How Do I Find Out What's Causing The Noise?
There are several tests that can be conducted when a subwoofer creates a weird noise. In the initial instance, where the noise is extremely low, there is limited action that can be taken. Nevertheless, you may request a replacement by contacting your customer service team.
You may test with the volume to determine whether the humming is amplified or minimized and then tend to exclude one or the other point. However, the sole method of determining the truth is to extract the cinch cable from the subwoofer input initially. You can be certain that a humming loop is the cause if the subwoofer ceases to noise after this step.
If the whirring sound persists, the humming loop can be ruled out, and the issue is likely to be mains interference or poorly insulated cables.
What Action to Take if Subwoofer Makes Buzzing Noise?
To determine whether the issue is related to the cable or power supply, attempt to connect the subwoofer to a different power outlet. If this method proves successful, reconnect the subwoofer to the previous plug receptacle, but this time, eliminate all other devices from the socket. Sometimes, the subwoofer may emit a murmuring noise as a result of the use of specific devices or charging devices.
It is possible that the murmuring is emanating from the loudspeakers. This is uncommon; however, it may occur when the cables are inexpensive or neglected. To evaluate this, either rearrange the cables or employ shortened ones. A mutable wireless subwoofer is an excellent option for integrating a subwoofer into your residence.
How Can You Get Rid of Subwoofer Humming Noise?
If the issue is a hum loop, it is important to determine whether the hum is the result of the connection between the subwoofer and the source device or of other devices that are also connected to the source device. Disconnect the antenna cable from the receiver (if it is a receiver serving as the source device) and verify that the subwoofer continues to resonate.
If it does not, the issue can be resolved by employing an intermediate sheath current filter to eradicate the hum loop. In the event that you are in search of an additional device, you may also locate solo subwoofers there. Disconnect all connected devices from the source device and observe which device interrupts the sound loop if it is not on the antenna cable or if it is another source device.
To prevent the hum loop, a galvanic filter must be installed between the source device and this device. If this does not resolve the issue, you should seek assistance from the appropriate source.
Bonus Tip: A little preventative maintenance can go a long way in keeping your subwoofer thumping happily for years to come. We all love to blast the tunes sometimes, but pushing your subwoofer to its limits can damage it and make the bass sound bad. Enjoy the bass, but be mindful of the volume.
The EndNote
Initially, determine whether the subwoofer's humming noise indicates the volume and whether it is generally silent or loud. This will restrict the potential causes.
The search for traces commences if the subwoofer is not the source of the issue. This may involve the replacement of receptacles cables or the disconnection of other devices from the power supply. Eventually, you will identify the source of the interference. Depending on the cause, it may be beneficial to replace a cable, connect a sheath current or galvanic filter, or seek technical support.
