Except for the exceptional one, people love to listen to music when they are driving. I personally love to listen to music louder on an empty road. But yeah, if you want to enjoy it like me, your car should have a system to make the car speaker louder. You can improve the sound system in a cheaper way and without an amp.
You may think that making the car speaker louder is not possible without an amp, that’s what most people think too. Although amp increase the volume but a good quality amp is pricey.
I know it seems counterintuitive that you don’t need an amp to increase the volume. But some simple ways can boost the volume and you don’t have to invest much money for it.
How to Make Car Speakers Louder Without AMP
The techniques are not critical and the sound will be clean and have havier bass. To know about it, keep reading the article.
Dampening The Sound System
When we driving a car, the engine makes noise and the car vibrates so the car audio system emits low sound. Sound dampening materials simply minimize those noise and vibration so the speakers will sound higher. It is not difficult to insulate vehicle panels. Some areas should be insulated, such as,
Car doors are the main points to pass the outside noise so dampen these areas are mandatory to reduce noise. The dampening materials will deaden the vibration and reduce outer noise so you will get a stable environment for your car audio.
The engine creates such a disturbing noise so dampening this area is important. Apply Dynamat or hush mat in the car hood so it will absorb the vibration and rattling so the car audio will improve. Although Dynamat is expensive but it has great effectiveness. They also eliminate the speaker resonance.
The boot and floor should be dampened too. The floor is an area that is very close to the road surface and it facing the tire and engine noise the most. To dampen the car floor, muffles, and boots to reduce those noise.
Use a Subwoofers
No other things can beat the amp, but a subwoofer can be the alternative of an amp. It can increase the music level of your car but it should be installed properly. It is almost similar to an amplifier as it functioning the sound system and increase the frequencies and bass so you will hear more powerful music sound.
The subwoofer can be used with or without an amp. The result will be the same. You can install it with its budget-friendly price and can utilize depends on your needs.
A subwoofer can produce bass and sub-bass. It has high frequency and you can use the best of it. Just follow some things such as, install the subwoofer in a less vibration place you can install it in the trunk and use a good subwoofer box.
Do not install it at the corner of your car as this place vibrates the most. After installing, properly fine tune the new subwoofer and adjust it phase so that it can give better sound.
Replace The Cables and Connection
Fresh cables and connectors increase the sound quality and wires also make the audio system in a shape. Regularly check the wire connection and do not use the old connection as it can create short circuits if there has any leakage.
Also, the sound quality depends on a good quality wire. Reduce the electrical impedance by regularly checking the speaker coils, circuits so the electrical signal can travel smoothly.
You should spend well money on buying good quality cable connectors. Get a good splice connector and splice them correctly. Do not use any worn out cables otherwise, the sound quality will drop. Remember, this type of work you should not do on your own.
Replace The Capacitor
The capacitor is the must item for using the subwoofer. It maintains the high bass and high energy so the loud sound won’t affect the car’s performance. This electric device improves the bass and stores high charge so the sound quality increases. Without a capacitor, the power will be dissipated and affects the battery. The stored energy will release only when the subwoofer needed it. If the capacitor is old, replace it with new ones.
Use Non-Invasive Add Ons
Sound dampening materials and subwoofer are not the only device that makes the sound loud and quality. The non-invasive add ons boost the sound system and you do not need the subwoofers.
Also, there are tons of gadgets that you can use to control the audio level. It properly tunes the sound and adjusts the frequency. The add ons are compatible with almost all car models. It is a portable gadget so you do not have to install it.
Just install a signal processor or an equalizer and use a Bluetooth or wireless system so the sound quality will be much better.
This type of gadget prevents the wiring hassle and has many features that you can also hear the music on your mobile with it.
Fine Tune and Crossover Setting
This is an important factor to set the fine tune and crossover to improve the sound and bass quality. There is a dial hat on the subwoofer, just turn it slowly and listen to the bass. Set the dial depends on your needs and the phase will set to give heavier bass. Also, the car receiver has a frequency filter that boosts the sound system. Set high pass filter to a full range speaker to get a clean sound in high volume. Check the crossover settings and bass frequencies as they can really improve the sound system.
Adjust the crossover setting and check the default factory setting. The sub crossover should be 60Hz and the mains will be the same. Both the crossover should be mains and sub combined.
Control The Tune Properly
The sound system comes with complicated settings. Ne of them is setting the proper tune. It is a very common problem to mix up the tuning controls so it’s important to set it in a proper way when you are on the driveway. The sound should be bearable and without distortion. So set the tune with a small bass boost, the highs and mids should be low and the other level is a little up. If you use an aftermarket receiver the tuner will be the same.
The equalizer setting should be proper to avoid the terrible sound. If you want deeper bass, set a smaller bass boost. Create some advance preset so you can set your desire to sound quickly and change it depends on the situation.
Tweek The Sound
The sound quality also depends on the car interior design. If the car seat cover is made from plastic, the sound reflection won’t be good. But if the surface has carpet and the seats are made from fabric or leather, you will hear good sound. The surface should have absorbent materials.
The speaker’s frequency should be a response to perfectly. So it is important to have an audio equalizer as it removes the sound peaks.
If you are lucky, you will get various tone control, advanced EQ preset in your car. Check the head unit and its control system.
If the options are less( only midrange, treble, and bass control features), use a digital sound processor to get multiple options to adjust the desirable frequencies.
Almost every digital sound processor has a built-in equalizer so it can eliminate the frequency peaks and enhance the sound system.
Select High-Quality Music Files
Your all hard work will go in vain if you have poor quality music files. Poor music files can not produce a great sound so it matters a lot. The sound system has a process called compression that boosts the quieter signal and reduces the dynamic range of sounds.
When you play music, the files enter the compression so it loses some frequency so the files should have a high frequency that makes the music quality full and soft for your ear.
So you cannot deny using the compression. Select as much as higher bit rate music files you can to hear the loudest and high bass music. Higher resolution music has a higher quality and better output.
Modify The Speaker
Speakers are the only things that give music output. It is an important part to set a good speaker for making louder music without an amp. Check the speaker condition and modify it if needed.
Purchase a powerful speaker and replace old parts. If you want to modify the speaker, change the coils as it releases the vibration so it should be strong enough to reduce any hassle. Also, change the magnet as it creates an electrical impulse.
Old and weak magnets won’t be able to handle the high frequency and vibration.
Speaker cones are also very important. Old and worn out cones can not produce much vibration so change it and re-tune the music. These are cheaper and you will get good sound from the speaker.
Electrical impedance lessens the music performance so it needed to reduce for better sound. The impedance should be matched with the files and speaker so the overall circuit should be proper in size and quality. If you have a small speaker, the file should have similar resistance.
Use Digital to Analog Converter
This device converts the digital music signals to an analog signal so you can hear much clean and fuller sound. Although most of the receivers do not have this option to bypass the system.
