Under the damping process, the user has to add premium insulating materials to the essential parts of the car. One has to identify the origin of the rattling effect and dampen those parts, such as the boot space, doors, and floor of the car. However, dampening is comparatively more straightforward than the home speakers as they remain in a static position. Talking about the car speakers, there is a continual vehicle movement. Because of this, it becomes a bit difficult for the user to dampen the components of the car.

Usually, the door dampers are affordable and readily available in the market. Besides, they also have an easy installation process. Meanwhile, there are multiple tiny hollow spaces between the seat of the car and the floor. Consequently, the speaker’s sound begins to distort. That is why; one must dampen the complete flooring of the car with insulating material.

“Likewise, the sound waves have a free-flowing pattern through which they reach the listener in the purest form. Your car’s boot space includes luggage and a subwoofer that determines the performance of the luggage and woofer. Thus, it will restrict the audio and disturb its flow too. To prevent this, dampen the boot space also.”

Use Tweeters

For all those marveling how to make car speakers louder without amp; tweeters are a great solution. These are crafted specifically for generating moderate-to-high sound frequency output with optimal bass level. Besides, tweeters are popular for improving the quality and volume of car speakers. Similarly, these deliver the audio with apparent and distortion-free bass effects.

Additionally, a tweeter and a subwoofer will take the music experience a notch higher. A tweeter enhances the audio output to a greater extent. Moreover, the sound quality of the speakers also depends upon the type of tweeter it contains.


You can use asphalt sheets to soundproof the car to improve the volume and quality of the sound system. Most importantly, apply the sheets to the interior of the frontal doors as they work as housing for the speakers. By doing so, you can quickly reduce the resonances and imprecisions to a noticeable level. Apart from that, the speaker will deliver intense and detailed bass at higher volumes also.

Non-Invasive Accessories

Still wondering about the problem? Give a shot to non-invasive accessories. Many handy add-ons play an essential role in tuning a guitar. Similarly, there are few gadgets that one can use to tune and control the volume levels of the car speakers. Commonly, these are known as non-invasive additions to the music system.

With the help of these, you can tune the speakers and the subwoofers too as per the requirements. For this, one can use a Bluetooth kit to regulate the music system wirelessly. Other than this, gadgets such as signal processors as well as equalizers will also suffice the requirement. An essential benefit of using such non-invasive additions is that they come at affordable prices and deliver significant results.

Engine Dampening

Undeniably, the engine is one of the most pivotal elements to look for as it can generate a thumping sound. Therefore, it adversely affects the audio quality and volume of the car speakers. Ultimately, one has to dampen the engine of the car to get rid of such issues. By doing so, you can control and enrich the performance of the music system.

Playing Highest-Quality Music

Playing Highest-Quality Music

If you are still dealing with the problem, here is another option for you. Though most people often overlook this aspect, playing the highest quality music defines the speakers’ audio quality. When one stream or downloads a song, there are several options such as 128 kbps, 256 kbps, 320 kbps, and many more.

Yet, there are multiple formats for playing the audio files; Mp3 is considered the best. Apart from delivering premium quality audio, it is also compatible with most music devices. On the other hand, playing songs of 126 kbps will provide the audio quality that of a radio. Above all, the songs of 320 kbps are the preferable ones as they offer the purest and high-quality sound output.

Utilizing Capacitors

Capacitors are efficient in regulating energy wastage while playing music. Similarly, playing louder songs with a whole level of bass can drastically affect the quality of the music system. Therefore, capacitors enable the user to listen to songs in total volume without causing any damage to the music system.

Do Not Compress Music

Compressing the music files can deteriorate the quality and sound of the audio to a significant level. That is why it is recommendable to compress the sound as least as possible. One must remember that the smaller the compression, the better the sound quality.

Replacing the Wire Connections

Wire connections aid in maintaining the quality of the audio system in good shape. Many people have this misconception that wire connections are made to last forever. Nevertheless, the radio cable or connectors of the car tend to wear out after a certain period.

Due to this, it is necessary to replace the old wire connections with new ones. By doing so, it will eliminate the perpetual music interruptions. Besides, you will get to experience maximum bass with crystal-clear audio quality.

Check the Audio System Circuit

Examine the wire connections regularly as they can hamper the electrical signaling inside the audio circuit. As a result of this, the sound quality will also deteriorate. Besides, electrical impedance interrupts the electrical signals from converting into audio. As the intensity of the disruption rises, the more negatively it impacts the audio system.

“Make sure that the specifications of the audio system and the speakers are in sync. Apart from this, check the complete health of the audio system circuit, including the speaker coils and the magnets. Ultimately, it will help in lessening the electrical impedance.”

Setting for Crossover and Phase

Setting the phase of the subwoofer along with the crossover frequency is very crucial. The quality of the sound and bass depends on the same. Because of this, the subwoofer should be in phase with the rest of the music system. Many subwoofers comprise a single-phase output or a variable dial set anywhere between 0-180 degrees. All one has to do is adjust the outlet or the phase dial to attain the desired level of bass.

A crossover and the phase of them work in synchronization to set the suitable frequencies. In particular, it assists in delivering seamlessly clear and smooth audio output. If the crossover settings are improper, it will cause the subwoofers and the car speakers to compete in bass frequencies. Consequently, the subwoofer and speakers will call off each other, thus causing distortion and unclear sound.

Contrary to this, if the crossover settings are apt, it will become easier to get louder bass output. In addition to this, it will also provide excellent quality sound even at the highest frequencies. Usually, it is vital to set the crossover to the optimal level of the subwoofer. Do not leave it at the standard factory settings.
