How to Increase Subwoofer Volume


The majority of people enjoy loud music, especially when the bass is robust. However, selecting the proper subwoofer might be difficult. Most individuals choose to purchase a costly, high-quality amplifier. In this post, How to make a subwoofer louder, I will instruct you on how to make easy tweaks to your subwoofer to regain or achieve greater sound without spending more money.

You must first become familiar with the many varieties of subwoofer enclosures. Enclosures enable the subwoofer to optimize its potential and function within the audio system. When the right subwoofer is paired with the proper enclosure, they protect the device and enhance the bass sound.

The enclosure you choose will depend on the style of bass you desire, such as boomy or tight.

Airtight enclosure

Due to the lack of airflow from the sealed enclosure, a higher wattage amplifier is required to drive the subs.

The enclosed enclosure is crucial because it creates superb low-frequency bass. It is the finest for playing hip hop since its bass is deep and precise. However, it is not suggested for jazz or rock, as it is less boomy and the music may not sound as well.

Portable/ventilated enclosure

One or two vents are located in the front or back of the box. The vents enable the production of tremendous bass without the need for a powerful amplifier. To be effective, the measurements must match the size of the box precisely. Do not estimate the size of the box by looking. Due to its proportions, the ported enclosure is louder and has more bass, making it ideal for hard rock and metal.

Bandpass enclosure

There are both sealed and ported enclosures present. It has two chambers, one of which is sealed and the other of which is ports and emits sound waves.

It is possible to have great low-frequency delivery performance while minimizing resonance. You are able to play bass for all musical genres. The bandpass should not be tuned to the port’s frequency, and this is something to be wary of. How to enhance the sound quality of a subwoofer

1. Adjust the subwoofer’s tuning

Adjust the unit’s parameters and listen to the output to confirm that louder and more precise sounds are being produced. If they are not properly adjusted, the main speakers and subwoofer will battle for bass frequencies and cancel each other out.

2. Secondly, insulation

As a method for enhancing bass, cabinet inside are coated with sealants. Also, adhere a soft material such as fleece or felt to the walls. This intensifies the bass.

3. Modify an amplifier

Play a music with a middle bass range, increase the volume to 80 percent, and if you don’t notice any distortion, increase the volume gradually.

4. Determine the correct size of enclosing box

Large subwoofer enclosures do not guarantee louder sound, only lower bass responses. If your box is larger than the optimal subwoofer, the sound quality will suffer. The excessive excursion of the free air will certainly cause harm to the subwoofer.

In contrast, a smaller box will generate more electricity to complete the same task.

Therefore, while picking the correct box for your speakers, be sure to select the correct one.

5. Position the subwoofers appropriately.

The position of a subwoofer has a startling effect on the level of the bass in your vehicle.

By positioning it in the corner, the bass is amplified by six decibels without the use of an amplifier. If the port is in the rear, leave at least 3 inches of space between it and the walls. The bass is amplified by placing them in an uneven location relative to the car wall.

6. Utilize audio files of excellent quality.

Currently, many players are attempting to compress their music files. This causes the audio to lose information at low and high frequencies as well as other characteristics, making the song energetic and loud. It is imperceptible while playing the compressed audio file through earbuds or headphones.

When selecting music files, prioritize those with a high bit rate. Certain formats offer the highest audio quality. It is FLAC and AIFF. Choose apps with a high resolution and make sure the settings guarantee great sound quality when streaming music.

When the music file is of excellent quality, it immediately affects the sound produced by the subwoofer.

7. Reduce electrical impedance

To function properly, a subwoofer must transform the electric charge into sound without restriction. Electrical impedance is utilized to determine the level of resistance a subwoofer encounters when performing this function. If your subwoofer has a high impedance, it is less able to transfer electrical charge into sound.

Ensure that coils and magnets are completely functional in order to minimize electric resistance. To determine this, the electronics that controls your subwoofer should be in excellent condition.

Consult a technician if any components require replacement.


8. Substitute the cable

If the wires in your audio system are outdated, they will interfere with the electrical communication, resulting in poor sound quality. The cables should be updated periodically, and they should be of sufficient quality and size.

9. Improve the heatsink

Heat affects many electronics. Subwoofer circuitry generates heat that might negatively impact the subwoofer. Most subwoofers have built-in amplifiers that generate a great deal of heat.

To rapidly dissipate this heat, a heatsink is installed. You can substitute a larger heatsink for your current one. Typically, heatsinks are positioned on the back of the subwoofer or on the circuit board.

A thin layer of heatsink compound should be put to the contact surface and the heatsink sides should be glued down because you cannot drill into the heatsink like you could with the original.


Amplifiers can be of great assistance when attempting to improve sound quality. Nonetheless, using the aforementioned suggestions, it is simple to attain the appropriate volume.

Moreover, if you must purchase an amplifier, you must consider which sort of amplifier is optimal for your subwoofer.
