If you’re an audiophile who likes loud speakers, you’ve probably wanted to upgrade your sound system at some point.

You would want your system to play louder, have more bass, and be easier to understand.

An amplifier is one of the most simple ways to make your speakers louder. But amplifiers cost a lot of money, and you might not have that kind of money.

How to make car speakers louder without amp will show you 13 ways to make the speakers louder without having to buy an amplifier. You might be wondering if it’s possible, and the answer is yes.

13  Ways of Making a Speaker Sound Louder Without an Amp

  • Change the voice
  • Play music of good quality
1.Get new wires and plugs.

It is important to remember that the sound system is not always to blame. Sometimes, a sound coming from your speakers could be caused by the wires and connections.

The cables and connectors that you use to wire your speaker system also wear out over time.

Even though the wires are covered in plastic, they are still made of metals like copper. Because of this, the wires lose their quality, which causes the volume of the output to be low.

So, I would suggest that you check the wires and connectors often and, if necessary, replace them with new ones. Buy 12AWG Speaker Wire to avoid the trouble that wires can cause. The cable makes sure that the sound is clear, and it is more durable and flexible than copper wires.


It’s a way to stop your car from rattling by adding insulation to the parts that make the noise. It is the best way to boost the volume of your speaker.

Most of the time, the design of the speaker’s enclosure and the space in which it is installed cause it to vibrate, which messes up the sound and makes the listener’s ears hurt.

This is easy to do with home speakers because they are set to “static mode.” But some parts of car speakers need to be dampened because the car moves all the time.

If you use this method on parts like the doors, floor, and trunk, you will see a big difference. You can get good dampers for the doors at any local auto parts store and have an expert put them in for you. Dampers for doors are also cheap.

Insulating materials are put in the spaces between the seats and the floor, where the sound from the speakers starts to distort. This makes the whole floor quieter.

Why dampening? Sound waves need to be able to move freely to get to the listener without getting messed up.

There could be things in the trunk, like luggage or a subwoofer, that affect how well the woofer works, and the luggage will block the sound, making it flow in the wrong way. So, the boot space also needs to be padded.

3.Put in a subwoofer.

You can also boost your sound without an amplifier by using a subwoofer.

A sub-woofer is like a full speaker. In simpler terms, it is the part of a woofer that makes bass and sub-bass sounds.

Most of the time, their frequency range is between 20 and 200 Hz.

The good thing about this is that you can use the subwoofers on their own or with an amplifier if you decide to get one later.

With subwoofers, your stereo system can make more sound.

Also, the placement of your subwoofer is a very important part of making your sound louder.

Install the subwoofer in a part of your car that won’t shake much, like a corner.

Putting it in a corner, on the other hand, will close the wall, which can often make loud, rumbling, and unpleasant sounds.

This problem gets worse if the sub-woofer has a hole that lets air in. Make sure the subwoofer is about 12 inches from the wall in this case.

Also, putting the subwoofers in different places will make the bass louder and the response smoother in general.

If the installation isn’t done right, your car speakers will be competing with the subwoofer for sound, so it’s best to get a pro to help.

4.Setting for the Phase and Crossover

Setting the sub-woofer phase and crossover frequency is also very important for sound quality and bass quality.

So, change the subwoofer’s phase and make sure it is in sync with the rest of the system.

You will also notice that most subwoofers have a single-phase switch or a variable dial that you can turn from 0 to 180 degrees. Change the switch or the phase dial until you get the most bass.

5.Add tweeters

Tweeters boost the sound, so you can hear music that is louder and clearer.

Tweeters, on the other hand, are made for high frequencies, just like subwoofers are made for low frequencies.

So, putting a subwoofer and a tweeter together will improve the sound quality of your music in a big way.

Also, keep in mind that the type of tweeter a speaker has usually determines how good the sound is. Putting in Power Acoustik NB-1 200-Watt 2-Way Mount Tweeters has improved and made it more fun to listen to music in my car. I would 100% recommend them.

6.Put in Crossovers

As was already said, phase and crossovers are very important for how well speakers sound.

They work together to set the right frequencies so that the sound response is smooth and clear.

But if you don’t set the crossover correctly, your main speakers and sub-woofers will compete for bass frequencies and cancel each other out. This will make the sound distorted and unclear in general.

7.Use capacitors

When you play high-bass songs in your car, you might hear rattling and reverberation. This wasted energy could affect how well your car runs overall.

When the sub-woofer doesn’t get the same amount of power, it usually doesn’t work as well. Because of this, capacitors are used with subwoofers to give them the power they need to work at their best.

Capacitors don’t supply this needed power all the time. Instead, they store the power and only send it to the sub-woofer when it needs to be at its best.

Using capacitors makes sure that the high bass from your speakers doesn’t mess up the way your car runs.

8.Reduce electrical impedance

Electrical impedance is the distortion or resistance that happens when electric signals are turned into sound by the audio system or speakers.

The less well an audio system works, the more impedance it has.

So, check the specs of your speakers and make sure they match the specs of your audio system for the best results.

This doesn’t mean that you should get smaller speakers. Instead, you should check the speaker coils, the health of the magnets, the state of your cable connections, and the whole circuit to keep the impedance as low as possible.

9.Put a speaker horn on it

A horn is a flared tube that is connected to the output of a speaker. It helps reduce audio impedance by bringing it closer to that of open air.

When it comes to speakers, how well they work is very important for volume and sound quality. Because of this, adding a horn is another way to make it louder without using an amplifier.

Putting a horn on your speaker will make it better at transferring, putting out, and using power.

The only problem is that air doesn’t behave in a straight line, which makes them warp when too much power is used.

Also, wind noises can get into the horns and make the sound distorted. This is caused by air moving against the surface of the horns.

Before you choose this option, you should be careful and do a thorough check.

10.Use add-ons that don’t get in the way.

There are many gadgets on the market today that you can add to your car that won’t hurt it and will make your sound system better.

Thanks to improvements in technology, these gadgets help tune and control the sound levels.

These devices are easy to use because they don’t need to be set up. You can take them with you even when you’re not in your car.

Also, it would be best if you never turned your sound system’s tone controls all the way up. Like any other musical instrument, you need to make sure it’s tuned right and change the frequency. Also, always have two or three presets for your audio Equalizer ready to go so you don’t have to mess around while you’re on the road.

You can control the output by mounting them flat and then changing one or two things as the music plays.

Buy a signal processor or an equalizer to keep the sound quality up. If the settings aren’t right, plastic and glass surfaces will reflect sounds in a crazy way that will make your ears tired.

Also, use Bluetooth or wireless systems so that you don’t have to deal with wires and their problems. They are also cheap, portable, compatible, and have a lot of other benefits.

So, instead of investing in wired sound systems, you can buy gadgets or systems.

Also, before you buy something, you should find out what options are on the market.

Also, pay attention to how portable it is, how good the sound is, and how many stations it has.

11.Enclosure with a door

Also, putting your speakers in an enclosure with ports will make them louder in general.

Ported boxes are great for getting more high and low frequencies out of the speaker. Because of this, this design is often used to make subs have a stronger bass response.

12.Change who is speaking

If you’ve tried all of these things and nothing has changed, it might be your speakers.

If something is wrong with the way the speaker works electrically, you may need to upgrade it and replace the broken parts.

You can also keep your speakers in good shape by doing things like changing the coil, the magnet, and the cone.

  • If the speaker’s coil starts to wear out, the force on the cones that makes them vibrate will go down, which could cause power loss. So, it needs to be changed.
  • The force of the magnet makes the magnetic field, which makes the electrical impulses, which make the speaker cones move. Magnets that are old and worn out have a weak magnetic field, which causes weak vibrations.
  • Speaker cones can also be torn or eaten by bugs. These cones can’t make strong vibrations. Because of this, you have to replace them.

The frequency response of the speaker will change because of all of these changes. When you put it back in your stereo, it won’t sound the same as before.

To sum up, you should make sure to re-tune the system after making any changes.

I think you should hire someone to do this for you. And sometimes it costs less to buy a new speaker.

13.Play music of good quality

As simple as it sounds, the sound from your speaker system is directly affected by the quality of the music you play.

So, if you want to play music that requires you to compress a file, don’t compress it too much.

In other words, the quality of the music will be better if the file is bigger.

For instance, you’ve probably noticed that when you stream or download music, you can choose from options like 128kbps, 320kbps, etc.

There are many ways to play an audio file, but the MP3 format is good enough for high-quality sound and works on almost all devices.


If your speaker tries all or some of these ideas, he or she will definitely do better.

This comes down to improving your audio quality however you want.

When looking at a new sound system, you should also think about what kinds of songs you like and want to play, how much bass you need, how clear the sound is, and many other things.

Also, don’t forget to ask for help when you aren’t sure what you are doing.
