5 Why Does My Subwoofer Sound Distorted Issues Explained


Subwoofers are an essential part of any speaker system and are used to reproduce low-frequency sounds that regular speakers can’t. While subwoofers can provide amazing bass, they can also be prone to distortions if not set up and maintained properly.

Why does my subwoofer sound distorted? If your audio has a physical problem, it could cause distortion. This can occur when a subwoofer is stressed beyond its capacity. Extremely high volume stresses the subwoofer’s cone material by pushing it far beyond its intended limits.

Distorted sounds can be really annoying and detract from your listening experience. In this blog post, we’ll discuss what causes subwoofer distortion and how it can be fixed.

We’ll cover topics such as placing your subwoofer in the right spot, setting the correct crossover frequency, and making sure your subwoofer is properly matched to your amplifier. We’ll also provide helpful tips and tricks to help you get the best sound out of your subwoofer.

Whether you’re a beginner or an experienced audiophile, this blog post should help you fix any issues you may have with car subwoofers or subwoofer distortion.

What is a Subwoofer Distortion?

A subwoofer distortion is an issue in which the sound produced by a car subwoofer is not clear and accurate but rather becomes muffled, distorted, or even noisy. Subwoofers are an important component of a car stereo and are responsible for reproducing low-frequency sounds such as bass and drums.

Bass distortion can greatly affect the overall sound quality of a car radio and may result in a muddled and unpleasant listening experience. This problem can be caused by various factors, such as improper setup or configuration, damaged components, or overpowering the car subwoofer with an amplifier.

To troubleshoot and fix subwoofer distortion, it may be necessary to adjust the gain control on the amplifier, check the audio inputs and connections, change the placement of the subwoofer in the room, replace damaged subwoofer components, or use an equalizer to balance the stereo system.

It is important to prevent subwoofer distortion to maintain optimal audio performance and a high-quality listening experience. Low bass frequencies and humming sounds may be a sign that the voice coil is damaged and the sound can’t pass well in the low-pass filters; that’s why the car subwoofers or car audio system has poor sound.

5 Main Causes Of Subwoofer Distortion

The common problem of distortion in a subwoofer can be caused by a variety of factors, including:

#1 Overpowering the subwoofer with an amplifier

When the amplifier is too powerful for the sub, it can cause the subwoofer to distort or even cause permanent damage.

#2 Incorrect setting of the gain control

Setting the gain control too high can cause the sub to distort the audio signal.

#3 Placement of the subwoofer in the room

The subwoofer’s placement can affect the quality of the sound produced. Placing the subwoofer in a specific corner or against a wall can cause distortion due to sound reflections and resonance.

#4 Connection issues with the audio source

Poor or faulty connections between the input source and the subwoofer can cause distortion or no sound at all.

#5 Worn-out or damaged subwoofer components

Worn-out or damaged components such as the voice coil, spider, or cone can cause distortion in the subwoofer’s sound.

How to Troubleshoot and Fix Subwoofer Distortion

Subwoofers are a critical component of any home theater system, responsible for reproducing low-frequency sounds such as bass and drums.

However, distortion can greatly affect the overall sound quality of a system and may result in a muddled and unpleasant listening experience. Here’s a guide on how to troubleshoot and fix subwoofer distortion:

#1. Adjust the Gain Control

The gain control on the amplifier should be set to the correct level to avoid overloading the subwoofer. Turn down the gain control and check if the distortion is reduced. Gradually increase the gain control until the distortion is minimized.

#2. Check the Audio Source and Connections

Poor or faulty connections between the audio source and the subwoofer can cause distortion or no sound at all. Check the cables and connections, and ensure that they are secure and correctly inserted.

It is also important to check the input source, such as a music player, and adjust the subwoofer equalizer settings to optimize the output gains. This should fix subwoofer distortion because of the subwoofer’s frequency response.

#3. Change the Placement of the Subwoofer

The placement of the subwoofer can affect the quality of the sound produced. Placing the subwoofer against a wall can cause distortion due to partial sound reflections and resonance. Moving the subwoofer to a more optimal position, such as in the center of the room or away from walls, can help reduce distortion.

#4. Replace Damaged Subwoofer Components

Worn-out or damaged components such as the voice coil, spider, or cone can cause distortion in the subwoofer’s sound. If there is physical damage to the subwoofer, such as a torn or damaged cone, it is best to replace the component.

#5. Use an Equalizer

Using an equalizer can help balance the stereo system and reduce distortion. Adjusting the EQ settings can help to cut or boost specific frequencies to reduce distortion.

When adjusting these frequencies, make sure you play good music files at high volume. Playing tracks at a higher volume helps you achieve that perfect bass boost.

A low and high pass filter can also help when it comes to removing distorted sounds from audio files. If you feel that tweaking these EQ settings does not help when it comes to improving your bass output, then it probably means that you may need a more powerful amp.

Tips for Keeping Your Car Speakers and Amp Working Properly

Speakers and amps are essential components of your car’s sound system, responsible for producing a clean sound.

To ensure they continue working properly, here are some tips:

#1. Use Quality Components

Invest in high-quality speakers and amps. They may cost more, but they will provide better car audio quality and last longer.

#2. Follow the Manufacturer’s Instructions

Always follow the manufacturer’s instructions when installing or using car speakers and amps. Improper installation or usage can cause damage and reduce performance.

#3. Use Proper Wiring

Proper wiring is crucial for optimal performance. Use the right gauge of wire for the speakers and amps and ensure the connections are secure.

#4. Keep the System Cool

High temperatures can damage a car’s stereo and amps. Ensure the car’s ventilation system is working correctly, and avoid exposing the components to direct sunlight for long periods.

#5. Regular Maintenance

Regular maintenance can help to keep the components working correctly. Clean the components regularly and check for any damage or signs of wear.

#6. Don’t Overpower the System

Overpowering the system can cause damage to the components, especially the speakers. Ensure the amplifier is not too powerful for the speakers and set the gain control to the appropriate level.

Make use of the low and high pass filters if necessary. This will allow you to lower the volume on any desired part of the frequency range. More power does not really translate into the best quality when it comes to car audio components.

DIY vs. Professional Subwoofer Distorted Sound Fix

When it comes to fixing amplifier distortion, there are two options: a DIY approach or seeking the help of a professional. A DIY fix can be cost-effective and satisfying, especially for those who enjoy tinkering with electronics.

With a little research, it is possible to troubleshoot and identify the source of the distortion, such as adjusting the gain control, changing the placement of the audio components, or replacing damaged components.

A professional will have the necessary experience and tools to diagnose and repair the problem, including removing the speaker cone or subwoofer cone and ensuring the sub is working correctly and safely.

Ultimately, the decision between a DIY or professional system fix will depend on the complexity of the issue, the individual’s skill level and experience, and the resources available.

The Correct Power Supply for Subwoofers

If you’re experiencing a distorted sound coming from your sub, it’s likely due to an incorrect wattage, impedance, or current. Subwoofers require a specific voltage and amperage, so it’s important to ensure you have the right suspension system to ensure optimal performance.

Furthermore, it’s important to use the right type of wire, as some power supplies require specific types of cords in order to work properly. Too much power can result in a clipped signal from the subs causing it to bottom out and potentially damage the equipment.

Purchase an amplifier that matches the impedance level of the sub and the speakers. Set the crossover point of the sub when the music is playing at high volumes so that you can achieve the perfect bass level for your system.

You need to ensure there are no loose wires and that your new subwoofer is connected properly to the car amplifier. Play around with the gain setting until you find that optimal setting and a decent bass volume.

How much distortion does a subwoofer have?

The amount of distortion a sub has depends on the quality of the woofer and the settings it is configured with. Try adjusting the bass booster setting on your powered subwoofers and set the low pass filter to at least 80hz to cut off any unwanted low frequencies.

Generally speaking, lower-quality subwoofers will have more distortion than higher-quality subwoofers. Additionally, incorrect settings for the sub can increase distortion levels. When you hear distortion at low volume levels is because of noise interference or because of a blown subwoofer.

A partially blown subwoofer would produce a distorted signal even if you are playing music at low volumes. That is why it is essential to check the condition of your audio equipment before your start tweaking any audio settings on your head unit or receiver.

Most experts recommend getting a new subwoofer if you find out that your current sub has a completely blown coil. When the amp gains are set too high, most subwoofers send out distorted signals. This can damage the coil, so it’s important to set the gain levels correctly to avoid damage.
