3+ Genius Ways On How To Fix A Subwoofer With No Sound

Can’t decide How to fix a subwoofer with no sound? Congratulations you’ve got the right place! 

Subwoofers are usually used in home theaters, game rooms or recreational areas and have that regular bass frequencies not caught by regular speakers. 

What is a Subwoofer?

A subwoofer is a special kind of speaker that produces the lowest registers of sound (bass). Subwoofers are easily available and can be purchased as stand-alone units or as part of an entire sound system.

Here’s how to fix a home theater subwoofer that doesn’t work. Look very carefully at every part of your subwoofer Before you start, you might want to inspect your subwoofer very carefully! If your subwoofer is linked to the TV or audio system subwoofer output, it connects to the subwoofer output of the TV. You must ensure that the power cable for the subwoofer is connected to a functioning electrical outlet.

If a subwoofer is not working, there might be an easy fix without consulting a specialist. The solution often lies in the signal source of the sound system. To determine whether a problem with the subwoofer itself or with your amplifier exists, you can check several items:

Are all secure connected speakers? Disconnect and reconnect all cables.

Is the power on?

Check if your subwoofer has an LED indicator light that says it is powered.

If there is no power, or you have a receiver with no subwoofer output, check to see if your amplifier has a built-in crossover control (on most integrated amplifiers, this is found in the setup menu). If so, ensure that the crossover frequency control is set to “off.”

Do You hear Any Sounds From Your Subwoofer?

To use the subwoofer, make sure that the speaker settings on your stereo system or TV have been configured correctly. If the speaker settings are incorrect, the subwoofer will not work. You may need to change the speaker setting. See the instructions for your stereo system or TV for additional information. Choose a different sound field if your stereo receiver supports different sound fields.  

If no sound or a distorted sound is coming out of the speaker, check to see if your amplifier has a built-in crossover control (on most integrated amplifiers, this is found in the setup menu). If so, ensure that the crossover frequency control is set to “off.”

Are all cables plugged in and secure? Check your speaker cable connections.

Is the subwoofer switched on? Verify that your power switch is in the “on” position. If you’re using an extension cord, make sure it’s not connected to a button.

What Causes A Subwoofer To Stop Working?

A subwoofer stops working if there is no incoming signal to the speaker.

Electronic components, such as the amplifier and power supply, can be damaged by surges in electrical current. This can lead to blown fuses or a capacitor that fails to provide the proper voltage for your sound system.

A loose cable connects one of several parts of your sound system. The damaged connection could be on a good system component, such as your amplifier or subwoofer. It could also be at the plug end on one of your speakers if it has become damaged.

A sound system with a single speaker and no other sound source can still produce sound without drawing much current from the power supply. In contrast, a sound system with multiple speakers draws more current from the power supply. One possible cause of a capacitor failure is an overworked or under-sized power supply.

A passive subwoofer requires an external amplifier to operate like other speakers in your system. A passive subwoofer can be used in a home theater setup with an external amplifier between the passive subwoofer and the receiver’s preamp outputs. The receiver is freed from the need to provide amplifier power to the subwoofer in this configuration.

How Much Does A New Subwoofer Cost?

1) If the problem is electronic and you don’t have the knowledge or expertise to resolve it, contact your manufacturer.

If the subwoofer is more than five years old, consider replacing it with a new model.

Electronic components have a limited life span, and an older model might need more repair or replacement costs than the unit is worth.

2) A professional electrician can help you find a new power supply.

3) If you do not have an electrician, contact your manufacturer to find one in your area.

1) The best type of DIY speaker is a subwoofer because they are easy to make and require only simple materials.

2) To make your DIY subwoofer, you need a suitable speaker enclosure and an amp.

The materials required for building an essential subwoofer are wood, screws, glue, paint/stain, drill with bits and amplifier.

3) To build one yourself, you will need some reasonably basic woodworking and electrical skills, as well as a good knowledge of how subwoofers work.

Next, you’ll need to decide what type of enclosure you want to make out of the form of material.

5) If your speaker is not shielded or grounded correctly, it can cause damage to nearby electronics.

6) You can also purchase a subwoofer and amplifier separately and attach the two to create your DIY subwoofer.

Inexpensive models are available if you decide on this route.

7) Once you have completed assembling your DIY subwoofer, test it with an amp separate from any other electronics or speakers in your system.

Ensure you are not getting any feedback or interference.

8) Try to match your DIY subwoofer with the rest of your speakers for the best overall performance.

How Do You Repair A Subwoofer

It is easy for a speaker to get a tear in the cone. But don’t panic, you can repair your subwoofer at home if you follow these instructions.

1) An average speaker is composed of two different components, the woofer, and the woofers amp.

2) If the woofer is in good condition, but the amp is not working, you can see if your local electronic repair shop can fix it and replace it.

3) The best way to test for a blown subwoofer or faulty amplifier is to use an ohmmeter.

4) A blown fuse can mean that the amp is shorted or not getting a subwoofer’s power cable supply.

5) To test if the fuse is blown subwoofer and needs to be replaced, or if there is another issue with the amp, you can use an ohmmeter.

6) You will need to find the speaker wires labelled “power” on your subwoofer’s amplifier and attach it to one of the ohm meter’s probes.

Then, touch the other probe to any screw or bolt on your subwoofer that isn’t part of the amplifier.

7) If you do not see a reading when you touch the probes together, then there is no power getting to the amp needed for the subwoofer to work.

8) If the amp is shot, you can try taking it to a local repair shop and see if they can fix it or replace it.

9) In some cases, the amp might be fine, but there might be no power getting from your home outlet to the subwoofer itself.

10) In this case, replace the power speaker cables with a new one.
