How To Increase Volume Of Speakers Without Amplifier?

1. Modify Your Vehicle’s Speaker

If your car’s speaker isn’t making loud music, you should first inspect your speaker before looking for other methods. Sometimes, there can be some electrical problems in the old speaker for which you can’t hear loud music.

However, you can skip this part of your concern is to hear loud sounds in the front row of the car. It’s because modifying the speaker includes fixing and replacing that may need some extra cash.

Anyway, here is some essential components that you should inspect first:

  • Inspect the coil: When the coil of the speaker has failed, it’ll reduce the vibration produced by the cone, which will lead you to loss of power. Consider replacing the damaged coil.
  • Inspect the magnet: The vibration on the cone is actually coming from the forces of the magnetic field’s electric impulses. If the magnet is worn out and old, it won’t create any strong electric impulse, which means weak vibration.
  • Inspect the cone: The cone of the speaker can be worn out or eaten by insects. A bad speaker cone can’t produce power vibration; as a consequence, low speaker volume.

If these three components need change, make sure you re-tune the audio system. However, it would be better if you take the speaker to professionals; otherwise, if you aren’t skilled enough, you may end up ruining the audio system.

2. Right Connectors & Cable Connector

If you’re having frequent interruptions while listening to your favorite music in the car, the possible cause behind it can be the wrong cable and connectors. Consider looking for cables and connectors that are compatible with your car’s audio system.

However, the worn-out cable can also be the reason. Over time cables get worn out, and you should consider replacing cables and connectors after a certain period of time. After changing the cables, you should hear a complete bass if the cables were the issue.

3. Use Capacitors


A capacitor is a device that is used for storing electric charge. This device controls the wasted energy pretty efficiently while playing music. And therefore, you can hear full bass and quality music in cars.

Adding this component to your car will allow you to listen to loud music and protect your car’s music system at the same time.

4. Add Speaker Horns

Adding horns is the most effective way to improve your car speaker’s efficiency. This component is a kind of flared tube, and these horns need to be attached to the output of the speaker.

When you add horns, it releases the sound in the air, which reduces air impedance. By adding horns, you can gain power’s better efficiency, transfer, and output, which means better audio sound inside the car. Adding a Subwoofer can be an excellent alternative to horns.

5. Add Tweeters

Here comes another effective way of increasing the volume of the speaker. Tweeters create a maximum bass level with a medium sound frequency and make the peaks better and more amazing. This will create a higher and more comprehensive alloy effect.

6. Install Noise Dampening

You must have experienced the mixed sound of the engine, surround noise, and music together unless you have a luxurious car. And these background noises have a significant impact on how you hear your favorite music in the car.

Fortunately, there are many products available in the market that effectively reduce the outer noise coming inside your car. However, these products can be expensive, and installing those products by a professional may add some additional costs.

7. Other Gadgets & Add-Ons

There are hundreds of add-ons and gadgets available to increase the volume of speakers with the amplifier, such as equalizers, BlueTooth, signal processors, and wireless audio systems.

If you choose BlueTooth as the additional gadget, you need to charge a BlueTooth speaker. These add-ons and gadgets also allow you to control the sound level.
