Subwoofer Stopped Working But Amp is ON: Reason & 4 Ways to Fix

Subwoofers are types of loudspeakers. Sub-bass is the low-frequency sound produced by sub-bass. It converts audio signals of the low pitch into sounds that the woofer cannot generate. Consumer products typically have subwoofer frequency ranges from 20 Hz to 2000 Hz.

The ranges have a diameter between 8 and 21 inches. Subwoofers have stopped working numerous times. Subwoofers should not be used for several reasons. Below I will explain all the reasons.

How to Fix the Subwoofer Stopped Working But AMP is On?

Subwoofer Stopped Working But Amp is ON: Reason & 4 Ways to Fix
Reason-1: Check the short circuit –

Subwoofers are usually stopped with the help of a short circuit. Electrical signals cannot pass through it in an emergency. A short circuit also prevents the current from reaching the Subwoofer and restricts the flow. The electromagnet will not be able to generate the power needed to drive the cone if the wires have the proper power, and a short circuit cannot produce the power.

Reason-2: A failure of the con seal –

  • An accurate frequency is critical for a high-quality sound to emanate from a woofer or subwoofer. Because of this, subwoofers must move the air at a precise frequency. A shift of air occurs in the cone of the speaker.
  • This movement makes the subwoofer move pulling and pushing. Materials are used to seal the cone. Damaged cones prevent air from flowing properly inside subwoofers. A damaged or broken cone seal, or if it gets damaged by a mishap, will cause the subwoofer not to function.

Reason-3: Failure of driver magnets –

  • Each Woofer and Subwoofer is fitted with a permanent magnet rather than an electromagnet. An electromagnet stays near the coil at the bottom of the Subwoofer to act as an electromagnet. Through the electromagnet, all signals are converted into voltage and current.
  • It is the electromagnet that drives the cone by attracting the permanent magnet. In order for a sound to be created, the electromagnetic pole must continue to work for the permanent magnet to remain functional, otherwise, it will cease to function and will not deliver the correct sound.

Reason-4: Insufficient power –

A permanent magnet in a Subwoofer will not work properly if the wires to the electromagnetic coil are not providing the right amount of power for the electromagnetic coil.

Reason-5: Speaker Magnets and Their Effects –

Effect of Magnets on Speaker

  • There are 2 magnet poles that students or children may be familiar with. The same magnetic poles repel each other when they are near, and the opposite poles attract each other when they are near.
  • Both magnets are attracted to each other for a reason. As a result, a magnetic dipole grows as a result of their proximity. Magnets that are dipoles do not have magnetic poles on either side of them. The magnet in the speaker works in this way.

The best subwoofer solutions:

You may also want to stop your Subwoofer for other reasons. Replace or remove your subwoofer if it is broken before replacing it. Follow these steps and your subwoofer will be fixed;

Process-1: Ensure that the speaker wires are connected and that the connection is secure –

Wires Connection Check

  • You should first check each amplifier, speaker, and receiver for anomalies when a malfunction occurs.
  • Any wires or cables that are damaged must be changed and a replacement one brought to fix the Subwoofer. If you are changing parts yourself, you should be careful to position them correctly.

Process-2: Power cables, outlets, and fuses should be checked –

Checking the Powers and Fuse

  • Standby LEDs are installed on almost all subwoofer devices, indicating active power. In the event it does not work, then you must first check the power strip and make sure it is securely plugged into a wall outlet. Subwoofers cannot receive power if there is a problem with the plugs.
  • Additionally, all the switches should be checked. Try plugging it into a different outlet if it still does not respond after reviewing these suggestions. Subwoofers often include fuses, and removing them may be required to replace them on occasion, but not always.
  • The fuse should be checked to determine if it needs to be replaced or not. Any questions regarding the fuse can be directed to a manufacturer.

Process-3: Check the menu settings and the system settings –

  • Ensure all wires and cables are in proper working order and then check your amplifier or receiver’s menu settings if any are incorrect.
  • In your absence, someone may have changed the settings accidentally. Be sure to pay attention to the menu settings.

Process-4: Turn on the subwoofer, check the connections, and set the volume –

Connection and Power is On

  • Ensure that all the settings and connections are checked again. The subwoofer should now be turned on after all has been verified. If you would like to transmit audio inputs from a Subwoofer to an amplifier or a receiver, check the volume levels on the Subwoofer first.
  • You should increase the volume gradually at first, keeping it low at first. When you have a Subwoofer that is working without a problem, determine the volume level.

Final Word:

When you have taken all steps, done all things, and if the Subwoofer quits working, or when the power is off, and the Subwoofer programs won’t work, there is no other option than uninstalling and then reinstalling.

Frequently Ask Question:

Question: What would cause a subwoofer to stop working?

Answer: Most speaker failures are caused by short circuits. Signals won’t reach the subwoofer if the wires providing the signal are shorted. Subwoofers will also be unable to receive electrical current and signals if they are short-circuited at the terminals.

Question: How Do You Tell if a Home Theater Subwoofer Is Blown?

Answer: Listening to the sound of your subwoofer, observing the way it moves, and using a multimeter to determine if the coil is blown will help you determine whether the subwoofer is blown. See if your subwoofer has blown at a low volume.
