How To Fix A Subwoofer With No Sound? Top Full Guide

If your subwoofer isn’t making sound, there are a few things about how to fix a subwoofer with no sound. First, check to ensure all the connections are secure and the power is turned on. 

If everything looks good there, the next step is to check the settings on your receiver or amplifier. Ensure the volume is turned up and the crossover frequency is set low enough for your subwoofer. If you’re still having trouble, you may need to consult your subwoofer’s owner’s manual for further troubleshooting steps.

To utilize the subwoofer, ensure that the speaker settings on your audio system or television are properly set up. The subwoofer will not operate if the speaker settings are wrong. You may need to adjust the speaker settings. See the user manual for your audio system or television for further information. If your stereo receiver supports several sound fields, choose a different one.

Whether your speaker is producing no or distorted sound, check to determine if your amplifier has a built-in crossover control (on most integrated amplifiers, this is found in the setup menu). If this is the case, ensure the crossover frequency control is set to “off.”

Are all wires connected and secure? Examine the speaker cable connectors.

Is the subwoofer turned on? Check that your power switch is turned “on.” If you use an extension cable, be sure it’s not linked to a switch.

What Causes A Subwoofer To Stop Working?

If there is no incoming signal to the speaker, the subwoofer will cease operating.

Surges in electrical current may harm electronic components such as the amplifier and power supply. This may result in blown fuses or a capacitor that fails to provide the necessary power to your sound system.

A dangling wire links one of the numerous components of your sound system. The faulty connection might be on a high-quality system component, such as your amplifier or subwoofer. If the plug end of one of your speakers has been damaged, it might be there.

A sound system with a single speaker and no additional sound source may create sound while using little electricity from the power supply. A sound system with several speakers, on the other hand, uses more electricity from the power source. An overloaded or undersized power source is one probable reason for capacitor failure.

Like other speakers in your system, a passive subwoofer needs an external amplifier to function. A passive subwoofer may be utilized in a home theater system with an additional amplifier connected between the passive subwoofer and the receiver’s preamp outputs. In this design, the receiver is not required to deliver amplifier power to the subwoofer.

How Much Does A New Subwoofer Cost?

1) Contact your manufacturer if the issue is electronic and you lack the knowledge or competence to repair it.

Consider replacing the subwoofer with a new one if it is more than five years old.

Electronic components have a limited lifespan, and an older model may need more repairs or replacements than the machine is worth.

2) A qualified electrician can assist you in locating a new power supply.

3) If you don’t already have an electrician, contact your manufacturer to locate one in your region.

How To Fix A Subwoofer With No Sound What to Do When the Subwoofer Isn't Working Properly

Before you begin, ensure that all equipment, including the subwoofer, is switched off. It would help if you never connected or unplugged any cords while turning on, should anything be damaged by mistake.

Examine the connectors and speaker cables. Check all cables and connection points leading to amplifiers, receivers, or speakers, beginning with the subwoofer. Check that the wires are securely connected and inserted into the proper locations.

The subwoofer inputs on the rear often connect to the subwoofer output on the back of receivers or amplifiers. Inspect the whole length of wire connections for flaws if the subwoofer is connected to speaker outputs on the receiver or amplifier. Replace any wires that look to be worn, ripped, or broken before trying to use the device again. Check the wires for functionality with a brief test.

Examine the outlets, power cord, and fuse. The majority of subwoofers contain a “standby” LED that illuminates to signify active power. Check sure the subwoofer is firmly connected to a wall socket, surge protector, or power strip if it isn’t lighted.

If the prongs of a plug fall out halfway, which is frequently enough to impede power flow, gently bend them, so the wire remains attached when you let go. Check that all connected switches (such as those on walls, power strips, and so on) are turned on. If the subwoofer still doesn’t turn on, try plugging it into a different outlet that you know works.

Inspect the subwoofer’s power cord for any damage or faults like you did the speaker cables. Some subwoofers have a fuse, which may or may not need the removal of a rear plate. Check to see if the fuse needs to be replaced, if it is a feature, and if you are comfortable working with electronics. Otherwise, first, contact the manufacturer or a local repair shop.

Examine the system and menu settings. If all the wiring and cords seem to be in fine condition, check the menu settings on your receiver or amplifier—you never know who could have accidentally altered everything. Check that the subwoofer is connected to the correct audio inputs. Check to see whether the subwoofer’s output has been reduced as well.

If the input device has speaker size choices, choose the smallest option first; occasionally, changing the speaker size causes the subwoofer not to receive a signal. Some receivers may enable subwoofers to work with a big speaker setting, so check your product handbook for further information.

Check the connections, power on the subwoofer, and adjust the volume. Turn on the subwoofer once all connections and settings have been checked. Before transmitting any audio input, check the subwoofer’s volume levels, receiver, or amplifier. Start with a low level and gradually raise it to see whether the subwoofer is operating properly. Use music test recordings with low-end bass content to ensure that there is no doubt one way or the other.

If Nothing Works, Consider Replacing Your Subwoofer

If the subwoofer does not power on at all, or if it does power on but does not play anything, it is likely faulty and must be replaced.

Connect a second subwoofer to the transmitting device if feasible to ensure the sender doesn’t cause the hardware fault. If the second subwoofer works, the original is most likely defective. However, before you begin searching, decide if you need a powered or passive subwoofer.

Why does my amp come on but no sound from speakers?

There are many possible reasons for this condition, and determining which one is to blame may be challenging.

One possibility is that the speaker cables are not properly attached. Check that all of the cables are firmly connected and that they are routed in such a manner that they may reach the speaker.

Another possibility is that the amplifier is malfunctioning.

Why is there no sound coming from my amp?

There might be several reasons why your amplifier isn’t creating sound. First, the amplifier may be switched off. Examine the power light to determine whether it is on and flashing.

If the power indicator is flashing but the amp isn’t turning on, it might be because something obstructs the amp’s audio output.

What causes subs to stop working?

Subs may fail for several causes. The most frequent is when the subs’ power goes out. It might be due to a clogged speaker if you’re having problems hearing the subwoofer inside your car.


A subwoofer is a speaker that reproduces low-frequency sounds, typically below about 20 Hz. Bass tones are important for music and home theater because they add depth and realism to the sound. If your subwoofer is not working properly, it can be frustrating.
