Car audio refit ten points for attention

Add Date:2018/6/16    Clicks:

There are a lot of details to pay attention to. Not only should you pay attention to the circuit problems, but also the characteristics of the audio itself and the professional technical level. These are the prerequisites to ensure a good sound effect. Now, have you committed these ten major car modification mistakes?

Professional technology of sound modification:
Many car owners are cheap in terms of sound modification. In addition, the sound industry has a good development prospect. There are people with different levels of modification entering the industry. Many car owners choose a cheap store at will for sound modification, but I have to say that sound modification requires certain skills. Experienced teachers are familiar with the circuit, details and techniques of the audio modification. The modified audio is also safe for us.

Amplifier capacity of audio head unit:
Many people like the sound quality of the bass effect. They also spend a lot of time on the power amplifier of the main unit of the audio system. During the debugging process, they feel that the sound quality is good. However, they still find that the battery voltage is unstable and the sound quality is obviously damaged. Using high-power power amplifiers can easily burn out the circuit. This is what we often say about spontaneous combustion in the audio modification.

There are a lot of details to pay attention to in the sound modification. Not only should we pay attention to the circuit problems, but also the characteristics of the sound itself and the professional technical level. These are the prerequisites to ensure good sound effects. The car owner should not modify the sound at will.

Ten Mistakes in the Modification of Car Audio

1: The more horns on the car, the better the sound effect
The more speakers, the better the sound effect. This is a big mistake that many motorists generally believe, but it is not. There is no equal relationship between the number of speakers and the effect of sound quality. The number of speakers is fine, not many. As long as the positions of each speaker unit are correct, the sound quality will come out naturally. More speakers will only destroy the effect of the whole sound field.

2: Install according to the original parking space of the car, and there is no trace after refitting
Please clarify what is refitting? Change means change. Especially now some cars don't have high pitched sound. Why don't we just replace the car mounted subwoofer? Obviously, this is impossible. Now, the most common modification method is that in order to get a better sound field effect, the treble is usually inverted on the A-pillar. Because the treble has strong directivity and weak penetration, it is necessary to modify the treble on the A-pillar. In fact, the current stores are basically responsible for the car owners in terms of the inverted mold, because it takes at least 6 hours for a pair of A-pillars to be inverted, and the technology is relatively high. In order to make the sound system work better, the modified stores only charge back some material fees. I think it is very good at this point. The real Lei Feng spirit has not been written in the diary.

3: Wire is worthless
Wire rods are not valuable. I believe that the modification shop has heard a lot of this sentence. In fact, as long as we think about the current wire rods, we can know whether the wire rods are worth the money at the price of a catty of copper. On the power line, only the slightly better lines are bundled with hundreds of pieces, and only 10 to 20 meters long. There are also speaker cables, audio cables, especially audio cables. There are dozens of cheap cables, hundreds of good cables, thousands of cables, and tens of thousands of cables. However, these so-called "worthless" wires play a very important role in determining the sound quality of the sound system. This is like a good sports car. If there is no good road, how can it run fast?

4: Tuning is free
Tuning is free, which is widely believed by many car owners. And I still take it for granted. Why does this happen? The reason is very simple. The refitting shop thinks that the stereo is installed at their own place, so when you tune it, you don't have to say that money is not money,. As we all know, car stereo tuning is the most difficult skill to learn and master. But why do people give away such skills for free? Yes, it is to make the sound system work better. However, the car owner does not know how much time and energy the mixers have spent on this area to have such skills. So, if you have a master who can tune your voice for free, buy 2 more packs of cigarettes for that master.

5: How long does the installation take? 1 day? Too long
It takes too long to change, and I believe this is the most common "excuse" we encounter. In fact, it's really hard for the masters in the car audio modification industry to do so. Because the car owners don't give enough time, the modification process can't be done well and can't be done. Even the simplest wiring is under the pressure of time pressure. I believe that the masters can't do it well if they want to do it well. So I suggest that you should give the teachers enough time to install the stereo.

6: The sound quality of the main unit of my original car is very good. The sound quality of the horn of my original car is very good
As we all know, no matter what kind of car is sold, it is the car itself. There are comfortable Mercedes Benz cars in the car, BMW cars with exciting driving, Volvo cars with safe driving, etc., but none of the cars says that the sound inside the car is very good. Therefore, modification is necessary to achieve good sound effects. So how to modify it? Please change it according to your personal needs. Because we want to play with the stereo, not by the stereo. Don't listen to anyone's bluff. You should know that you should only buy the right thing, not the expensive one.

7: I listen to people who say that the loudspeaker sound quality is very good
I listen to people who say that the sound quality of the speakers is very good, which is a fatal misconception. You should know that we install the stereo to listen to ourselves, not to others. No one understands and feels the sound differently. It is suggested that you should not worry about speakers, power amplifiers and mainframes. You have to know for yourself what kind of sound style you want to select a good sound system with your own style. This is like going to a restaurant to eat. Do you think the dishes that others like are delicious? The truth is very simple.

8: Why is my bass silent?
Why is my subwoofer silent? The most frightening thing about professional car audio modification is to hear this sentence. Tell everyone that there is no sound from the pure bass. Why are there different speaker units in the stereo? Because each unit is responsible for different posts. The treble is responsible for high-frequency sound, the mid-range is responsible for mid-range, the mid-range bass is responsible for low-frequency and some mid-range, and the subwoofer is responsible for some ultra-low frequency sounds. Of course, there are more subdivisions in the frequency response. But with a good sound system, you can't hear the sound from the rear speakers, even feel it.

9: Can we not do sound insulation?
Can we not do sound insulation? With regard to sound insulation, some people think it is not very effective, while others think it is necessary. I think a good sound system has a lot to do with sound insulation. In fact, we all know that the same set of speakers sounds very good in the sound test cabinet. How can they change their taste when they are moved into the car? The answer lies in the speaker. The purpose of sound insulation is to make the door panel close to the sound. Because the sound is generated by vibration, the car is not sound insulated. When the stereo is turned on, the horn vibrates, and the car's iron sheet vibrates, which will offset many low frequencies. The effect of the stereo is naturally greatly reduced.

10: I want to listen to music on a USB stick
I want to listen to music on a USB stick. I think this sentence is very understandable in the eyes of ordinary people, but if it is seen by enthusiasts, it will be very different. But listen to music, only if you feel good about it. After all, the current dishes are not cheap. Although the sound quality of the USB flash disk is poor, it is more selective.
