How to Make Car Speakers Louder Without Amp? 7 Best Ways.

1. Damping

Damping is the most effective technique you can try doing if you want to boost your speaker’s volume.

Most of the time, due to the design of the speaker’s enclosure and also because of the space in which the speaker is installed, a vibration effect is created which makes the audio output distorted, hence disappointing to the listener’s ears.  

Damping is a savior in these situations. It is nothing but a method of adding insulating material to your car parts where the effect of rattling is produced.

Performing this technique is easy for home speakers since the speakers are in static condition. But when it comes to car speakers, since there is a continuous movement of the vehicle, there are certain parts that need damping.

Dampening parts like doors, floor, and boot space will be enough to notice significant results.

For doors, you can get good quality dampers in any local car accessory shop, and ask them to install it for you. Door dampers won’t cost much at all. Just a few bucks and you are all set.

Since there are lots of small hollow gaps between seats and floor, the noise from speakers starts to distort. Dampening the complete floor with insulating material proves to be a great idea.

Sound waves have to flow in a free pattern to reach the listener in a pure form. Your boot space might include a subwoofer and luggage which will affect the performance of the woofer as well as luggage will restrict the sound and make it flow improperly. Hence, dampening boot space is necessary.

2. Using A Woofer

Adding a subwoofer to your car audio system can be a deal-breaker. If you really don’t want to buy an amplifier and still wonder how to make car speakers louder without amp, a subwoofer is an answer.

Subwoofers are generally loudspeakers that take low-audio frequency output from the stereo and amplify the sound to a comfortable hearing bass level.

So it can be said that subwoofers are great alternatives for amplifiers. The subwoofer is of two types – Active and Passive. Passive subwoofers need an external amplifier to power them. What you need to look for is Active subwoofers because they come with an in-built amplifier.

Another reason to choose a subwoofer over an amplifier is that a subwoofer provides the desired sound output at a low cost compared to an amplifier.

Also, note that subwoofer placement plays a major role in its performance. In cars, locate them where there’s enough space on all the sides of the woofer to avoid vibration, hence the sound won’t distort and flow in the whole space fluently, without any interruptions.

So, if you love playing David Guetta and Martin Garrix i.e. heavy bass songs, then gifting your car a subwoofer that is good and compatible with the stereo and speaker system won’t dishearten you, ever. Click here to check out the specifications and price of the Skar Audio Amplifier.

3. Adding A Tweeter

For those who don’t know, just as subwoofers are designed for low-frequency output, tweeters are loudspeakers that are designed to create high-audio frequency output.

So the combination of a subwoofer and a tweeter will take your music experience to a whole new level. A tweeter is used to enhance the output sound. Most of the time, the audio quality of the speaker is determined by the type of tweeter featured in it.

4. Consider Using Capacitor

You must know that playing high-bass songs sometimes creates a rattling and vibrating effect in your car and this dispersed energy somehow affects the performance of the vehicle.

This is where the capacitors come into the scenario. Often, when subwoofer does not get the specific power supply, they perform poorly. Hence, capacitors are used with subwoofers to supply them with the power they need to give their best.

It doesn’t provide the required high power continuously. Instead, they store the energy and supply the power to the subwoofer only when peak performance is demanded.

Using capacitors also ensures that your car is running smoothly without getting affected by the high-bass output from the speakers.

5. Wires & Connectors

After a good number of weeks and months, speakers and subwoofer start delivering weak sound output which is undesired, right? Maybe it’s not the sound system that is at fault this time.

Wires and connectors involved in wiring the speaker system tend to lose their quality with time.

Even though wires are coated with plastic, but they are still made of metal like copper, they start to lose their quality which leads to low output volume.

Hence, it’s always a good idea to check on the wires and connectors frequently and replace them with new ones if needed.

6. Using Non-Invasive Add-ons

If you are still figuring out ways on how to make car speakers louder without amp, non-invasive add-ons are something that you can give a shot at.

Just like the small and handy gadgets are used to tune a guitar, there are similar gadgets for tuning and controlling the volume levels of your car speakers. These gadgets are known as non-invasive add-ons.

With the help of such technology, we can tune the subwoofers and speakers as per our needs. Using a Bluetooth kit will make it easier to control the system wirelessly.

Another great advantage of using non-invasive add-ons is that they are not expensive at all. Just a few bucks and you will see significant changes.

While tuning the system, make sure you know what you are doing. Because improper tweaks may lead to the worst outcomes. And you obviously don’t want to worsen the speaker’s output than it already is, right?

If you have no idea about what it is and how it works, seek help from an expert or a professional.

7. Play High Quality Music

If you tried everything and still can’t see any improvements (which is quite not right), here’s the last but not the least option for you. Play premium quality music. Yes, as simple as that.

This is a rare scenario but a considerable one.
