Effective Ways of Making Your Car Speakers Louder

There are numerous ways that you can approach the task of improving your car speakers’ sound output. Below are some of the most commonly used ones.

  • Car Noise Isolation

Whenever you’re driving, your car makes a lot of inaudible noises that mess up the quality of the music you listen to when you drive. Using asphalt sheets can help you soundproof your car for the best music experience. 

To effectively soundproof your car, there are three areas that you need to address – floor, engine, and doors.

Your car’s floor causes distorted sounds and shock, which affects the loudness of your car speakers. Insulating your car’s floor properly will ensure that your speakers sound louder and with better audio quality.

Next, you should focus on dampening your engine. The engine is a vital part of the vehicle, and it handles a lot, which contributes to all the noise it emits. To automatically boost the levels and quality of your music experience, you need to muffle your engine.

Finally, you need to cushion your car doors. There are many types of sound-deadening materials that you can use. Check out the Superlite Dynamic travel kit which is great for cushioning your car doors.

  • Adding Tweeters

You could also add some tweeters to help improve the sound of your car speakers. Tweeters are great at making the peaks or drops in music clearer, more precise, and more impressive. They also improve the bass of your speakers and create modest sound frequencies.

Tweeters are one among many accessories that are available on the market to help you boost your vehicle’s speaker output.

  • High-Quality Sound

The first step you should take is to ensure that you’re playing high-quality audio files. Avoid using files that have been compressed, as the process compromises the audio file quality. Low-quality audio files are likely to produce minimal sound output.

To avoid this side effect of compressed audio files, you need to ensure that you only use high-quality music. For music with great quality, you should check out sites such as Spotify and Apple Music or go old school and get some original CDs.

  • Sound Damping

Another solution for dealing with the noise made by your moving car is by dampening it. The constant moving of your car causes it to produce noise that affects how well you hear your car speakers. Luckily, there are several materials that you can use for dampening the noise.

To ensure that your car speakers get louder, start by dampening your car door speakers. You need to stuff the dampening material behind the windows, in the space within your car door. 

To silence the engine, which is an enormous source of external noise, you can install a hood liner kit. You can also use dampening materials to create a layer that keeps the engine noise out.

  • Add Some Subwoofers

Factory speakers aren’t good handlers of power and hence generate low-quality sounds. Subwoofers are a great solution to boosting your car speakers as they function as speakers too. Subwoofers are a good idea as they are capable of functioning with any sort of good sound system. You can easily adjust your subwoofers to ensure that your car speakers are producing the highest quality of music.

To ensure optimal performance, ensure that you place your speakers in corners of your car that don’t get a lot of vibrations. Some examples of subwoofers that you can use include Orion HCCA 12 12”, Alpine R – Series subwoofers, Focal Performance subwoofers, and Kenwood KSC-SW11 among many others.

  • Using Capacitors

Playing loud music in your car tends to damage your music system over time. To rectify that problem and hear the music clearer, you should use capacitors. These babies control the excess energy lost from music playback.

Capacitors also ensure that no matter how loud you play your music, your car audio system doesn’t get affected.

  • Replacing Wire Connections

Car speakers have wires that carry the waves from the sound system to the speaker, and currents from the power source to the sound setup. If you want to keep your car’s sound system playing quality music, you need to ensure that you replace the wire connections from time to time.

When the radio connectors and cables will start to degrade and wear off. This will lead to issues such as music interruptions and poor bass.  

What Would Make Your Car Speakers Quiet

If your car speakers sound like they’re getting low, you need to get them fixed especially if you enjoy playing music while driving. 

Before fixing your car’s sound system, you first need to identify what the problem is. This problem can arise as a result of a few factors that we’re going to address here. They include the following.

  • Highly Compressed Audio Files

First, you need to consider the type of music that you’re playing on your sound system. Some audio files are of such poor quality that it doesn’t matter how good the sound system you play them on is.

Too-compressed audio files are a poor choice for music and they contribute to sound quality. These audio files are normally found on sketchy sites, YouTube downloads, and burned CDs.

To ensure you have a great music experience in your car, you need to invest in higher-quality audio files. Though original CD tracks are the best option, they’re not popular which leaves the subscription download sites.

  • Wrong Wiring

You should ensure that the polarity of your wiring is right when connecting your speakers to the car sound system. If you connect a positive lead to a negative one, there are going to be problems such as distortions, flat sound, and silence at times. Mixing up the wires affects the mid-bass of your speakers, which is the main sound that we hear.

Though it may seem obvious, it’s easy to mix up the connections during installation due to their many similarities. Always ensure that you double-check the polarity of the wires before connecting them to your head unit.

  • Poor Tuning

Finally, consider checking the tuning dials of your car stereo system. The car sound systems come with sound alteration aspects such as fade, bass, and treble. If these dials aren’t set properly, they could affect your car’s speaker’s sound output.

Though the aim is to make your car speakers louder, you should never max out the dials when tuning the sound system. This will only result in distorted noise that could even damage your speaker. It’s best to balance them as that will produce good quality music that is ideal for enjoying.


  • How can I make my car speakers louder?

There are many ways that you can use to make your car speakers louder to enjoy your music. These include the use of subwoofers as additional speakers, capacitors to salvage wasted energy during playback, soundproofing, and through noise cancellation.

If you’re going to improve the sound quality of your car speakers, you should always give figuring out what the problem is, your priority. The source of your sound problem might end up being caused by a small issue such as poor-quality audio files.

  • Does adding an external amplifier make speakers louder?

Yes. Using an amplifier will make your car speakers louder. An amplifier makes the sound waves emitted by your speakers louder. On the downside, using an amplifier will end up consuming a lot more power than your sound system normally does.  

Though unpowered speaker setups need an additional amp to make them louder, powered speaker setups have an inbuilt amp and can function properly with an external one. However, you can make these powered car speakers louder without an amp by adding some other audio output devices.


If your car speakers don’t sound loud enough, one great way of improving them is through the sound-deadening material and ideas that we’ve covered. Though things such as dampening your car doors and engine aren’t tricky, you should have a professional do it. You want to ensure that they do the job right and leave no spaces for noise to sneak in.

Only shop for high-quality music files that will complement your sound system to provide you with a great music experience. If you decide to use an amplifier to make your car speaker louder, you should be ready to see the power consumption of your car’s sound system go up.
