If you are a music lover and own a car, then the sound quality and loudness of the speakers might be your major concern. You can resolve this problem with the addition of a power amplifier. It will boost your sound volume and give you clean power. But the problem is, the amplifiers are quite expensive. Everyone could not afford it. In this scenario, the next question that comes into your mind will be how to make car speakers louder without amp.
In this regard, you can make a lot of simple additions to your sound system and make it much better without an amp. Some of these tips and tricks are the addition of high-quality music files, subwoofers, capacitors, tweeters, digital-analog converters, EQ parameters, new cables, and a seal around the edges of speakers. These are easy to make suggestions with minimal or zero investment. There will be a lot of other benefits like distortion-free, clean, vibration-free, and powerful sound. Let’s have a look at these features to make car speakers louder without amp.
14 Ways To Make Car Speakers Louder Without Amp
Here are some of the handy methods that can play important part in making your car speakers louder.
1. High-Quality Music Files
First of all, you must check the quality of the music files you are playing. Quality means the bit rate of audio files. The bit rate sounds simple, but it has a significant impact on the quality of sound. Normally, people use highly compressed small audio files downloaded from sites like YouTube and low-quality MP3 files. However, if you subscribe to Apple Music or Spotify music, you can download high-quality audio files. This is the only way you can get high-quality music files.
2. Clear The Surroundings Of The Sound System
Loose items have a great impact on the quality of your sound system. You must ensure that the pockets of car doors, center console, and glove compartment are free from any kinds of these items. The wires of the speakers must also be taped down properly rather than left to bounce. For crisp and clear sound, you should eliminate all the unnecessary things as soon as possible.
3. Noise dampening
If you don’t own a luxury car, you will have to hear many engines and road noise. The background noise has a considerable impact on the quality of sound. Some products are available to reduce both the exterior and interior noise. These might be expensive, but once you install these things on your car, you can significantly reduce the level of noise in your vehicle. In this regard, use dampening material inside the doors behind the windows and around the engine. Most simply, you can install a hood liner kit and the dampening material in the bay firewall.
4. Use subwoofers
One of the simplest ways to increase the volume of car speakers without an amplifier is by installing good quality subwoofers in your car. Place the subwoofers at such places where there is no disturbance and any form of vibrations. For a maximum bass generation, please place them in the trunk rather than corners. It would help if you also fine-tuned the subwoofers to make them in phase with your sound system.
5. Addition of tweeters
Besides subwoofers, you can also add tweeters for extraordinary improvement in your sound system. With the addition of tweeters, the audio system will emit the louder bass and keep the music clear and distortion-free. The addition of tweeters with the subwoofers would be a great change in your system in terms of quality and loudness.
6. Use capacitors
Sometimes, when you play high-bass songs, these songs will generate rattling and vibration effects and impact driving performance. In this scenario, the capacitors will be highly useful. Normally, the capacitors store power and give it to the subwoofers when they need it to provide excellent performance. Capacitors don’t offer ability continuously but keep it. It is only given when peak performance is demanded. The car will provide you with a smooth performance if you are using capacitors in speakers.
7. Digital to analog converter
A digital-to-analog converter converts digital information like zeroes and ones into analog music signals. Nowadays, we rely on smartphones to listen to wireless music. These devices come with a built-in DAC system, which is good enough for casual listening with the help of earbuds. But you cannot get the same performance as you can achieve from the more DAC system. With this advancement, you can get a fuller and clearer sound. You can easily pass the built-in DAC by connecting I-pod or smartphone via cable in the several new receivers.
8. Use receivers EQ parameters
Usually, the interiors of the car are not acoustically perfect for sound quality. It happened when the sound is reflected from hard surfaces such as glass and plastic. Hard surfaces reflect sound while softer bodies like carpet or seat cover absorb sound. These things led to a peak in frequency response and made the bass and shrill of the music boomy and causing ear fatigue.
You can easily get rid of these peaks with the help of a car audio equalizer. Many modern car receivers are coming with built-in equalizers or preset equalizers. If there is only midrange, treble, and bass control in your head unit and you cannot replace them, use the outboard equalizers. It will provide you with multiple ways to adjust your frequency response, and you can easily iron out the peaks. Moreover, the digital sound processor is also a good thing for increasing bass response and eliminating frequency response peaks.
9. Replace speaker cables
The state of the wires is normally overlooked, but it greatly impacts the loudness of your car speakers. If you use cheap and undersize cables, then these cables will prevent the free flow of current from the unit to the speakers. Resultantly, the speakers could not operate at their maximum potential. Over time, the cables lose their effectiveness. Thus, you must regularly check and replace these cables to feed the speakers with the right amount of power.
10. Avoid out-of-phase speakers
The speakers are connected with the stereo system with the help of wires. The positive side is associated with positive output, and the negative side is combined with a negative outcome. If the positive, negative are mixed up, then the out-of-phase speakers might impact your sound quality. It will result in hollow base notes, too high treble, and clarity issues. So, thoroughly check the speaker’s wiring after installment.
11. Seal around the edges of speakers
The easiest way to improve the quality of your sound system without an amp is to fill the gap between the car’s panel and speakers through a seal. In this regard, you must use the speaker gasket tape with an adhesive backing all around the edges of your speaker. It will create good sealing between your speaker and panel. After doing this, you can enjoy clearer, louder, and completely distortion-free sound.
12. Built-in tuning
Nowadays, every car speaker is coming with a built-in tuning system. By tuning, you can easily adjust the fade and balancing of your speakers. For the increasing volume of car speakers, you must set the fade and balance in the middle.
13. Electrical impedance
The amount of resistance required to prevent the electrical signal from turning into audio is called electrical impedance. The impedance and sound quality are inversely proportional to each other. With more impedance, you will get low quality and lower volume sound. To get rid of this problem, you must ensure that the circuit is working efficiently and the speaker magnet and coil are in perfect form. The cable connections should also be good.
15. Non-invasive Adds-on
Despite adding the things mentioned above, if you still don’t know how to make car speakers louder without an amp, you can also add non-invasive adds-on for excellent improvement. Like the small gadgets are needed to tune the guitar, non-invasive ads are also required to control the volume and tuning of the speakers. With this technology, you can easily adjust the speakers and subwoofers. Moreover, if you have a Bluetooth kit, you can also wirelessly control the system. The non-invasive adds-on are also not much expensive. You must know the whole procedure thoroughly. Otherwise, you might get the worst outcomes.
