Going for a long drive with your friends but the sound quality of your car speakers kinda sucks? Well, we totally get you. The whole journey may get spiritless if your favorite songs are hardly reaching your ears although it’s already set at the highest volume.
Some people like to use an amplifier in such cases to improve the sound quality. Amplifiers target the low-voltage signals at the input terminal of your speaker, amplify them and turn them into stronger power signals which release out of the output terminal. Therefore, you get to hear louder and more nuanced music.
However, if you don’t have an amplifier and would like to know how to make car speakers louder without Amp instead, we have some super useful suggestions coming right up for you so keep scrolling.
Top 12 Ways to Make Car Speakers Louder Without Amplifier
If you don’t want to install a high-quality amplifier for your car speakers, we would recommend the following alternatives that work as good as amplifiers:
1. Use a Sound System Compatible With Your Car Audio
If the audio system in your car is not compatible with your speakers, it can occasionally result in poor sound quality. Setting up a sound system made exclusively for your car’s audio system is the greatest solution in this situation for solving the low-sound problems.
2. Car Noise Isolation
Asphalt sheets are a great way to soundproof the inside of your car doors and dampen unwanted noise. This will help to get deep bass at high volumes as the in-coming noises coming in from the surroundings of your car will be highly reduced. You may not be able to install asphalt sheets yourself so we recommend asking a professional to do it.
3. Upgrade Your Car Speakers
If you bought a second-hand old model car, you shouldn’t be surprised if it came to you with trash-quality sound systems. On the contrary, even if you bought a brand new car, it’s still possible to receive poor-quality speakers because many manufacturers don’t put in much effort and spend money over the speakers while designing the car.
For such cases, we recommend upgrading your car speakers and replacing them with better-quality ones.
4. Install a Subwoofer
Specifically designed to reproduce low frequencies, subwoofers are one kind of loudspeaker that will come super handy in your miserable situation. Most traditional full-range speakers can only cover around 20 kHz of the frequency spectrum, but a subwoofer does the magical job of filling in the challenging-to-generate bass range up to about 40-200 Hz.
Therefore, subwoofers can be a great replacement to amplifiers because it makes the low-frequency sounds become louder and not to mention, with subwoofers you can fully regulate the volume and sub-bass to your liking.
But make sure the phase and crossover frequencies are set up correctly in the subwoofer. The phase dial set should be angled anywhere between 0° – 180°.
5. Decorate The Inside of Your Car With Sound Deadening Materials
When we’re driving at very high speeds, our cars tend to vibrate more and create noise that affects the car speakers’ sound quality. Hence, in order to “deaden” the unnecessary noise, we recommend keeping soundproof materials over the metal parts to reduce vibrations and unwanted car noise.
Some common examples of sound deadening materials include: OSB, fiberglass, plywood, plasterboard, acoustic hangers etc. You can also add insulators to your car. This way you’ll be able to hear clearer sounds coming from your car speakers despite the road noise and engine vibrations.
6. Detect Any Obstructions or Placement Issues
Often, if your speakers were not installed or mounted properly, it’s possible that some screws still need more tightening and because of improper installation, the sound quality is being affected. What you should do is give a thorough check and make sure there are no direct obstructions between the speakers and the listeners for better sound-quality results.
Also, you must check if the grilles of your speakers are not smothered with dust and debris which could also obstruct the path of sound waves releasing from the output terminal.
7. Ensure Proper Electrical Wiring
If your speakers are wired improperly and also if the electrical wiring set is not of durable material or has become damaged somehow, it could also cause the speakers to generate low buzzing sounds instead of louder. Therefore, you may do it yourself or seek help from an expert technician for a thorough wiring check-up.
8. Use an Equalizer For Better Sound Quality
If you want to bring out the best audio quality possible from your car speakers, there’s no better substitute for an equalizer which will help you extensively adjust sound settings such as increasing the bass and boosting up the treble to create louder sounds.
Not only that, an equalizer offers unique customizable settings for different groups of music such as jazz, pop, rock, classical etc. You can also increase or reduce the sound frequencies.
9. Get Rid of Your Old Car Stereo
If you’ve been using that old worn-out car stereo for decades now, we think it’s high time to replace it for a better car stereo. You should upgrade the factory radio and add more power to your car stereo to enjoy more volume, clarity and bass.
We have observed that using the higher car stereo of your car’s receiver greatly helps in raising the bass to match the music beats and generally produces cleaner and clearer sound quality from the speakers.
10. Bring in Some Capacitors
Did you know? Capacitors are a great way to retain energy and reduce wastage of energy when you’re playing loud music on your car speakers. With the help of capacitors, you can hear big and loud sounds without causing excessive bass in your car.
11. Don’t Compress Music File
If you have a habit of compressing the file sizes of your music audios, it’s likely that the sound quality is being negatively affected as well. Remember this golden rule – the lower the audio compression, the better the sound quality.
We recommend playing songs that are between 256 kbps to 320 kbps and recommend MP3 format for better results.
12. Use Tweeters
Tweeters are very useful when it comes to improving the sound quality of car speakers, particularly because tweeters can play sounds of frequencies up to 20,000 hz and can make peak tunes sound more crisp and clear.
Installing a tweeter to your car speakers is very easy – see those holes under the speaker grille? Using a wrench, screw up your tweeter into those holes and you’re good to go.
Out of all the suggestions we’ve provided, if you only decide to follow one, you may not get better results as per your expectations. We recommend following at least 3-4 of these guidelines to see noticeable improvements in the audio sound quality of your car speakers.
Oh and if you don’t wanna spend bucks on purchasing subwoofers, sound dampeners, tweeters, better wirings and stuff, you can check if your car speakers are covered in the warranty certificate instead. Then you can enjoy a free upgrade or replacement of your old car speakers depending on your car company policies.
Frequently Asked Questions
1. How can I increase the bass in my car speakers?
Answer: You can use a powered subwoofer to increase the bass and an amplifier with RMS. Additionally, non-invasive sound frequency regulators such as an equalizer or tweeter can also help to increase the bass. Moreover, you should also upgrade the current car stereo in your vehicle because honestly, in-built stereos aren’t powerful enough to reproduce clear and deep bass.
2. Does adding car speakers increase volume?
Answer: Theoretically yes, the more car speakers inside the louder the volume – but remember, having multiple car speakers won’t guarantee better and clearer sound quality. For the latter, we recommend upgrading your existing sound system with better wiring, better capacitors, subwoofers, tweeters and amplifiers instead of increasing the number of speakers in your car.
3. Why are my car speakers not loud?
Answer: Sometimes, even if your car speakers are set at max volume in the settings options, the sounds are still not as loud as they used to be before. Possible reasons for this can be – worn-out speaker drivers, piles of dust and debris all over the speaker grille holes, damaged wiring, blown fuses, poor-quality stereo, loud engine noises and vibrations, etc. Or perhaps the issue can be external, such as the volume is mistakenly set at low in EQ settings or you’re playing low-quality audio files.
4. How do you get deep bass?
Answer: In order to get a fat, deep bass sound, you must use a low-pass filter to cut out and reshape the higher frequencies of the bass notes. It’s also possible to enjoy deeper and better bass output simply by enlarging the diameter of your speaker box. Lastly, to get deep bass of a bandwidth between 16-80 Hz, you can take help of an amplifier or subwoofers.
