How to Make Car Speakers Louder Without an Amp

Last Updated on

Driving is much more enjoyable with a good music system. And what better way to achieve that than by having premium car speakers that produce louder audio without compromising the sound quality? Unsatisfactory speaker volume can be a nuisance, especially when you don’t have an amplifier to rectify it. And when doing away with the entire sound system is not an option for you, the best way to handle the situation is to improve the car speakers without an amp

9 Tips To Make Your Car Speakers Louder Without An Amplifier

Below are some of the ways you can manage to make the necessary improvements to your music system to achieve excellent audio performance without needing an amplifier. Moreover, you can use the best 6.5 speakers without an amp to enhance bass and sound quality.

1. Add Subwoofers

It goes without saying that subwoofers work miracles in any sound system without an amplifier. They are designed to enhance the performance of a speaker system in terms of sound quality, clarity, and resolution. However, You should take careful consideration when it comes to placement. They must be placed away from any vibration, preferably in corner placement. 

Moreover, ensure that their phase is optimally adjusted for superb performance. Research the amazing subwoofers available on the market and make a pick depending on your needs. There are several related articles on the same subject. 

2. Check the Audio System Connectors and Cable Connection

Notably, your car’s cables tend to wear out after some time and will need replacement if you can’t stand the subsequent horrible audio and low sound from your speakers. It may not be the go-to option for many given its complexity, but sound-lover or not, the last thing you need is constant music interruption. Therefore, regular checking of the cable connections is advised as it can save you from getting an unnecessary amplifier. 

3. Go for the Aftermarket Speakers

Another trick you can go for is brand new aftermarket speakers. You can choose them over your factory speakers, which could be the solution you have been looking for. And when you are in the market for these speakers, high sensitivity should be at the top of your specification list. To be specific, anything above 92 dBA should be your goal. With this, you are assured of clear sound, deeper bass, higher clarity, and higher resolution. 

4. Sound Proof the Car

You often realize that external noises, such as road noise, are factors that significantly reduce music quality, even when you have an amplifier. Sometimes, car owners may ignore this when installing door speakers. The result is low bass and generally poor audio quality—increasing the volume when in motion is also not the best solution. On the contrary, more distortions will be heard than the music.

That is where sound-dampening materials such as rubber or foam come in. Add them to door panels to reduce vibrations. These materials absorb the external noises and vibrations and ensure maximum bass production. The best part is, with these improvements, you won’t need an amplifier. 

5. Use Quality Audio Files

Another overlooked aspect of improving car speakers is the quality of music being played. When streaming tracks, there are usually several quality options to choose from and multiple formats. If you want to achieve the best sound output, choose the highest quality of music. 

6. Add Tweeters

Another way you can make your car speakers louder without an amp is to modify the car’s audio system, which may include adding a tweeter in the door panels. Some cars have them pre-installed and they work just fine, so there is no need to replace them. However, if your car does not have any, you should work towards adding them to your speaker system. The tweeters are invaluable for adding high-frequency sounds.

7. Modify the Speaker You Already Have 

If you are looking to get the louder audio without adding an amp, modifying the speaker currently in use should not be farfetched. This should be done with one’s budget in mind. Improving all the speakers in the vehicle to get more sound and power is affordable. It will translate to higher-quality sounds. 

However, some car speakers tend to output distorted sounds with time or faulty signals. It may be possible to troubleshoot the distorted audio, but modifying the speaker from the beginning is a more practical solution. The high-quality ones will even offer the luxury of making the car’s volume seem higher. 

8. Configure the Crossover and Phase Controls

Setting the crossover frequency and subwoofer phase also goes a long way in improving the car audio system. These factors directly affect the bass as well as the sound quality. Therefore, it comes down to ensuring that the subwoofer phase is compatible with the overall music system. Different subwoofers have different variations in terms of phase levels. You will adjust the phase dial to get the best bass production.

It is important to note that the phase and crossover work in synchrony to attain optimal frequencies, particularly ensuring that the audio output is smooth and clear. Therefore, fine-tune the crossover controls for optimal bass boost. This makes it easier to achieve good sound quality at high frequencies and with louder bass. 

Conversely, improper crossover settings mean that the car speakers and subwoofer are competing in bass frequency delivery. In this case, you will have to deal with the unclear sound and constant distortion.

9. Accessorize with Non-Invasive Gadgets 

You need to have an open mind when thinking about how to increase the volume of your speakers without needing an amplifier. With that, you can consider accessorizing with some non-invasive gadgets as they play a role in tuning. Some handy add-ons are designed to control and tune the volume levels of your speakers. These gadgets include equalizers and signal processors. 

For convenience, you can use a Bluetooth kit that allows wireless control. These non-invasive additions come in handy to attain the optimal performance of subwoofers and speakers. The best part is that they come at reasonable prices and guarantee superb performance. 


Above are the simple and affordable methods you can opt for to make your car speakers louder for cleaner and louder audio. And when all is said and done, you will notice a massive impact on the overall sound system of your car for the best music experience.
