How To Make Car Speakers Louder




Cars are one of the most popular sources for audiophiles to listen to their lovely music because it helps you to spend your leisure time in a better way while driving into your city.

Are you looking to get more detailed & loud volume from your car speakers but Don’t want to spend money on purchasing a new speaker system?

Don’t worry!

Speakersmastered is here again to help you make a deal for your enriched audio system to pack some quality audio with loud volume for your long drives.

Besides getting a good set of car speakers for your vehicle, we will give you some tips that may help you sound better & louder. First of all, you will have to make sure, what is your ideal case scenario for your car audio system.

If you think that your car speakers do not provide a loud sound, that can fill your cabin entirely or at least for the max, then you can optimize them for sure. But if you already have enormous sound, that can get out of your cabin easily, then don’t dare to do this.

Because it is noise pollution first that is going to disturb the environment, plus this can cause an explosion inside your car. So be clear on your needs.

For this thing, ask a local but experienced & professional car audio installer for honest advice on what gear you should get and why.

Because we are not aware of what model of car do you own, what is the size of the cabin, how many hours do you spend in your car, etc. Be super clear on such things.

But for here, we will be giving you some do’s & don’ts for your car audio in order to get quality & louder sound.

How To Make Car Speakers Louder – Step By Step

If you have a custom car audio system, for that you have upgraded your factory sound system to the current one, you can keep trying these helpful things to improve your listening experience.

And first of all, you need to know if the speaker you are buying is the best for you. Because at the moment there are many types of speakers, of which 2-way and 3-way are quite well known.

And unless you know the speakers properly, how do you make your speakers louder? So read 2-way and 3-way speakers at once.

1. Use Gaskets Tape

This little thing may leave a significant impact on your car audio system, that you can’t even believe.

You might be thinking why do I get this useless & cheap hack, but “you are definitely wrong”.

If you are not getting a good quality & loud sound, there’s a chance that there have some installation & mounting issues.

Now, you have the option of getting it uninstalled first, & later installing it properly. Does it make sense to you?

Obviously not, you will not get any significant improvement but this will become more hectic for you. Instead, you can use a car audio gasket tape to get cleared.

This gasket tape will insulate the speakers from vibrations & will stabilize the speaker mounting efficiently. This tape is a kind of foam tape, that has a wrap on one side, and you will be peeling its adhesive layer in order to install it on your speaker’s ring.

This way, you have successfully partitioned the front wave from the rear wave of your speakers, & you have also canceled most of the air that was reaching from one side to another. Now, you will not get any distortion in your listening while driving that will also positively impact the loudness.

I am pretty sure that this gasket will help in most cases because it is specifically made for car audio, plus it is a cost-effective method.

2. Figuring out the Polarity

Now, if that gasket method does not work, figuring out the best polarity should work. All speakers work on a polarity, in which your speaker has a pair of positive and negative leads.

Here, you have to make sure that the positive terminal of your head unit is connected to the positive terminal of your amplifier.

If you have installed speakers on more spots, like one is on the driving side, two are at the rear doors & the other sub is installed on the back, you might have linked your amplifier or head unit’s opposite (or) reverse, which is now causing a minimal output.

If the polarity is wrong, there’s a huge loss depending upon your number of speakers. To check this out, simply figure out the labeled terminals of speakers to your amplifier/head unit.

If these are parallel, it’s super good, you do have to check somewhere else.

But, if it doesn’t, make sure you connect them properly. Just, pick your terminals & a clock battery by connecting them to each other, that will help you figure out the right terminal.

If your speaker is coming out, it means your speaker’s positive terminal that you are touching to your positive terminal of the battery is actually positive.

If you are some sort of techie, you can do this check on yourself. Do this yourself only if you know some sort of technicalities. Don’t use this method on sensitive speakers.

You can also use a polarity test tool, to get cleared on what you have performed.

3. Tune Your Sound Control

This method is for you, if your speakers are okay, & do not have any technical issues. Try tuning your factory-made or aftermarket head unit, to calibrate it.

Just use balancing and fade in your sound controller to improve your sound. You are just shifting your center sound image to your most near speaker, probably the driving seat spot.

If you have multiple speakers installed in your car, which is the ideal case scenario, then you can simply move your sound backstage to your favored side, inside your cabin.

If you just want your speakers to sound louder as much as they could, just position your fade in the center. Or you can shift the sound on your front seats if you are an audiophile.

4. Get Rid Of All Clunking

If you have a lot of spare stuff in or around your center console, your car dashboard, and doors, you can’t imagine that you are blocking your sound.

You might have some random, spare & hard things, stored in your storage compartments, that keep messing & hitting each other as you keep going on accelerating the car.

It is just for sensitive speakers with a sensitivity of less than 90dBs. This thing you can find on your speaker’s box, if you have installed aftermarket car speakers, or you can check it on your speakers as well.

This stuff is referred to as sound-deadening materials in the car audio system, which is actually ruining the sound quality & loudness. These materials absorb the distortion and muddiness that is coming out.

As soon as you push your car & your speakers become the worst, believe me, this could be the problem & the biggest issue that you can’t even

imagine. Another thing you should keep tightening the screws next to the speaker grill. Sometimes, your amplifier with loose cabling also causes your speakers to sound way lower.

5. Improve/Choose The Right Music

Most of us are too energetic & time savers persons, who just browse music from Youtube & turn that video into a music file, to play that in your car. This is the most common & simple problem with most of us.

Basically, whenever artists upload their project to youtube, that file downgrades a little bit, that later loses some of its quality.

Whenever you play music on youtube & get it downloaded through converters, it again loses its quality, which makes the audio files of low quality.

When you play that file on your phone, you barely feel any distortion because you are playing on a very little medium & sound level.

But, when you play it on your speakers, that file is going to be heavily compressed, which is not going to sound much good & loud.

Now, this is why audiophiles don’t recommend youtube for playing genres on your car audio, because this is not actually meant for it.

You should keep considering purchasing a monthly subscription to audio such as Apple Music & Spotify, to get the most out of your car audio.

When you are transferring those audio files to your device, make sure you have selected the highest quality instead of automatic quality. Audio files with 320 Kilobytes/sec or FLAC files are recommended to play.

This will definitely consume more data and time, but you will be saving your speakers at the same time.

6. Using The Best Volume

This is the thing, which you can improve right now after figuring this out. If you are using your mobile as an input device/music source, you will be playing music from it by pushing the sound level all the way up on your phone.

It is just an addition to music improvement and loudness, but you should avoid this bad habit.

Because most speakers do lose their quality because of internal vibration, which leads to sound distortion. This may also cause damage to your speakers if you are using an underpowered amplifier.

By overcoming this, you will surely get a clear & crispy sound with beautiful loudness.

Another thing you should try is to select the correct frequency for your speakers. Almost every speaker, with no matter of factory-installed, or aftermarket, will get a frequency rate on that system, on which the speakers are most comfortable to play.

If you are exceeding that limit, you are more likely to ruin your speaker’s loudness & clarity which is not a good habit.

You can find this information about your speaker, in the box if you have not wasted that, or you can enter that model name on google to get all of its technical information.

Usually, speakers starting from 50Hz are likely to do well in terms of both loudness & clarity.

7. Using Gain As Volume

Another mistake or a bad habit, that most of us are currently doing is that; they use the gain knob as a volume knob or a bass-boost knob, which is freaking wrong. In fact, they don’t even know the difference between these two knobs.

Obviously, your volume knob is to control the volume level to turn your volume loud or low, depending upon your desire, but the gain is a different thing.

This is basically used to match the distortion level from your plugged-in device to the distortion level on your amplifier. Whatever signals your device is transferring, it involves some data loss & some distortion always at different voltages.

If you turn the gain all the way up, the amplifier is going to clip, because you are not allowing the amp and your device to match the distortion and voltage. This bad habit can not only damage your amplifier, but this can also damage your speaker by causing an explosion.

If you have your audio system professionally installed, don’t mess with these things. Professional car audio mechanics uses professional equipment, to figure out the exact distortion, & they later set the gain accordingly.

8. Aftermarket Head Unit/Amplifier

Now, if you don’t want to mess with the amplifier, try getting an aftermarket head unit that already has a built-in amplifier, so you can make your speakers sound louder.

This is a bit costly option, but if nothing works for you, it’s better to change your head unit entirely which is not much recommended at least unless you have a new car with a pretty good head unit.

Alternatively, you can just get an amplifier, connect your speakers to that amp & you are all set, even if you have a new (or old) car. It will put more power to your speakers, a relatively cost-effective way.

9. Electrical Upgrades

Sometimes, if you study some sort of sound engineering, you will get to know that after some quality equipment, your sound quality depends on the way you installed your equipment.

You have to make sure that you are using the recommended, compatible & capable power cables & electrical components, which can run your amplifier & speakers.

Make sure to upgrade the wiring if you haven’t done this yet or add an additional battery if you don’t want to get underpowered in terms of driving your car.

If you don’t use recommended electrical components, you will get poor quality sound, dimming headlights or indicators, that might ruin your battery.

10. Getting Over-Sized Subwoofers

If you have got a new car, or you don’t have much idea about your requirements and you have chosen a way bigger subwoofers, this is a huge mistake in your car audio.

You are living in the 21st century & you no longer need to have massive & super technical equipment to get a good sound experience.

Gone are the days when people preferred the size of any piece of equipment to categorize that thing as a good one.

This is not the case anymore, at least for car audio. Sometimes, smaller subwoofers with proper airspace can easily outrank the big subwoofers.

You need to focus on your needs such as figuring out the point where you will be installing the sub.

This could be indoors, dashboard, or under the seats (for large vehicles). You need to take the measurements yourself simply the volume of your car cabin, or you can also contact a professional car-audio installer who is an expert in such stuff.

It will help you select the best-recommended speaker with sufficient driver size, economically.

11. Max Wattage Myth

Some newbie audiophiles confuse it when it comes to wattage. They thought that the higher the wattage, the higher the sound quality. This thing is somehow true, but you need to clear on this as well.

Most of the speakers have two wattages, one is called RMS & the other is peak power. You have to make sure that peak wattage has almost nothing to do with the sound quality or loudness.

This is basically the highest value that the manufacturer of the speakers had tested so far. It only refers that your speaker can manage that much wattage for the most. If the power exceeds that peak wattage, you are more likely to blast it.

For example, we have reviewed a JBL GX600C by JBL in our guide of best 6.5-inches car speakers, where we have mentioned the 400W peak power wattage & an RMS of 140W.

Considering these values, If the power/wattage exceeds this peak limit, your speaker can cause an explosion due to overpowering.

If your input is less than that RMS (140W) at less than that recommended voltage, your speaker’s cone & some other components will break out due to underpowering. Plus, this can also damage your amplifier.

11. Max Wattage Myth

The type of port that your speaker box has also has a lot to do with loudness. The most common ports are round ports and slot ports. Normally, if you have if both have the same cross-sectional area for both ports, they will sound the same except that slot ports are easier to incorporate into designs.

The Bottom Line

Here in this article, we have discussed some tips that may be helpful for you on how to make your car speakers louder & sound better.

Most of these tips, may or may not need a professional car audio mechanic, which means little to no expense. But, some things may involve a bit of expense, depending on your case.
