First, car audio conversion program
If you search for the current economical in-car audio improvement methods on the market, you will find that the main focus is on the following: replacing the CD host, installing an MP3 player, replacing the MD head, plugging an MP3 converter, and improving the speaker. The investment varies from tens of yuan to several hundred yuan.
Improved CD host
More and more cars are now equipped with CD hosts at the factory, but in the middle and low-end cars, the cassette heads still occupy a considerable share. Here, we introduce a host improvement solution for those who do not meet the car audio system. If the speaker effect of the car is still correct, consider replacing the head of a Alpine CDE-9841. The market price is about 930 yuan. Advantages: It can completely change the sound effect of the car, and the display panel of the machine head is fine. At present, the quality of the machine at this price can be considered as the top quality. Disadvantages: There is no other function than playing a CD.
Add an MP3 player
If you count the most popular music playback equipment at the moment, then the non-compact and flexible MP3 player is the only one. Due to its small size and large capacity (a 256M MP3 can hold at least a hundred high-quality songs), you can also play the characteristics of editing songs according to your own habits, so it is the most popular music gadget. In fact, it is not difficult to get the MP3 in the pocket into the car. At present, many car audio manufacturers in China have launched a car CD host that can directly connect to the MP3, and only need to go to a professional audio conversion shop to replace a new type of car. The audio equipment will allow the car to embrace the MP3. For example, there is a machine called GoRun Songyun 6110 on the market. The market price is around 950 yuan. It is a versatile car music player that can be compatible with U disk, MP3 player, SD/MMC card, CD CD and MP3 format. CD, even ié„„POD can be eaten. Advantages: greatly improved the audio convenience of the car. Disadvantages: The sound quality is naturally a lot worse, and the line modification is more troublesome. It needs to be modified by a professional qualified audio store.
Replace the MD head
For those car owners who like to make some moves by themselves, nothing is more suitable for them than a set of car MD. MD is a kind of disc with digital recording format, which enjoys high-quality repeated recording, which greatly facilitates the special use of personal music. Advantages: Recorded music, meetings, class recordings, live music, etc. can be played in the car in time, and all the loved songs can be edited on an MD disc and enjoy digital sound quality. Disadvantages: The price is high, only suitable for a few enthusiasts.
Add MP3 converter
For consumers who have both an MP3 player and a CD head, it is the owner's greatest wish to have a "communication". Don't worry, people have seen this market huge, so a device called MP3's in-car audio converter (also called receiver) came into being. The working principle is to convert the audio source of MP3 into FM signal, and then receive it through the radio of the host computer. Although the sound quality of MP3 live broadcast is not good, it is better to no longer have to modify the line inside the car. Advantages: Small investment. The conversion from MP3 to in-car audio can be solved with only a few tens of dollars. Disadvantages: poor sound quality. It is similar to listening to the radio.
Speaker improvement
For those audio systems that have a good match in the original car, the owner can no longer have to toss the electronic equipment. If you only want to improve the sound quality in a targeted way, you can selectively replace some of the speakers in the car, or add a power amplifier. However, this requires a professional audio store to match the different sizes of the car. If the owner is a fan of pop music, then a pair of 6×9 woofers is very necessary. Generally speaking, the sound quality of the 6×9-inch speakers on the market is about 500 yuan/pair. If the owner of rock music prefers to add a subwoofer, it will be able to get around 300 yuan. The change is quite big. Advantages: low investment, obvious effect. Disadvantages: After all, there is no system matching, so there will be concerns about the stability of use. In short, the audio conversion in the car varies from person to person, depending on the money. Sometimes, spending a small amount of money can bring about big changes.
Second, modify the car audio precautions
One day not long ago, a car that was burnt to the face of unrecognizable was dragged into the car repair shop. The owner confessed that this was the result of his own modification of the car stereo that caused the circuit to be short-circuited. He also revealed that it was a car stereo installed in a car wash shop. Recently, car fires caused by audio line problems have been on the rise.
Experts remind consumers to buy car audio not blind, to ask more, read more, listen more, learn more, avoid being fooled. It is necessary to go to a professional organization to modify the car audio.
Let me see you more
In order to attract customers and promote products, merchants often fake domestic audio equipment into imported products. Some dealers claim that their products are produced in the United States and the United Kingdom, but consumers can find flaws as long as they pay attention. For example, take a look at the packaging, whether there is a place of origin, Chinese characters, and whether there is an import license. Some manufacturers have faked famous brand products such as Sony and Pioneer. In this regard, we should carefully observe whether the manufacturing process of these products is rough. In addition, check the manufacturer's sales license, listen to the sound quality, go to the audio manufacturer's website to check the product serial number is also a simple way for ordinary consumers to identify the product.
"emergency" often cannot be wise
Some young people have a higher heart. After buying their first car, they often want to decorate their car at once. In fact, they may not be able to give birth to wisdom. This is easy for the unscrupulous car dealers who sell cars and the owners of car audio. They colluded with each other and used the consumer's lack of understanding of the car stereo to deceive the owner. They install high-quality products and charge a high price difference. In this way, the owners of the car not only can not appreciate the good music, but also cause a series of joint quality problems. And once a problem occurs, it is a problem for the owner to clarify the responsibilities and claims here.
Think twice
When buying a car stereo, don't make a blind decision, think twice. Car audio is a semi-finished product, only professional design and configuration, professional installation and commissioning, in order to achieve the desired state. For the choice of equipment, the car mainly knows the reason, using the general equipment, through reasonable matching and debugging, the sound effect can exceed the value of the equipment itself. Therefore, for the average car owner, it is not necessary to deliberately pursue all the devices from the power amplifier to the subwoofer, and the quantity needs to be entered. The best use of the car sound is the principle of selecting the car audio.
Speaker amplifier has more water
Some merchants use the customer's price sensitive characteristics to minimize the host price, even lose money to sell, and then configure low-end power amplifiers and speakers for customers to obtain high profits.
Parallel sound can not be
Now on the market, there is a part of "parallel imports". Some car owners think that parallel imports are mixed and have certain advantages. This idea is wrong. When purchasing a car stereo, you cannot choose parallel imports. The first is that the national law does not allow it. Secondly, it has no warranty. Once it is damaged, it has to pay for it. The standard of some parallel imports is different from the current broadcasting system in China. The radio can't be used normally. In addition, the service life of the repaired products and refurbished machines is also very short, and it is difficult to guarantee the quality.
Install audio also invoice
Before installing the car audio, the owner of the car should use his own observation to determine whether the seller has professional installation tools, after-sales service capabilities, etc. If necessary, he can directly request the merchant to check whether there is a manufacturer-approved sales authorization certificate, business license, Car audio professional installation training certificate, etc., which can also protect their rights and interests from infringement to a certain extent. The product must have a formal warranty card, fill in the sales date, and cover the effective seal of the sales unit. Consumers should also carefully read the warranty terms, confirm the warranty time, the warranty location, and request invoicing.
"Looks beautiful" don't believe
Some people pay attention to the appearance when purchasing the host, choose the host that looks beautiful, and do not consider the inherent quality and performance of the sound itself. If the panel is to be beautiful, the production cost will inevitably increase and the sales price will increase. In addition, if the audio panel has graphic balance and high brightness display, it will also affect the driver's observation of the road when driving at night. If you want to install a sound and cheap audio system, you can't choose this kind of flashy model. Some of the very good brand models, although seemingly simple in appearance, are well coordinated with the car dashboard, and the expressiveness and sound quality of the music are first-class.
Volume, power is not the only
Some young people feel that they are not strong enough to use the host to push the speakers. A power amplifier is required. There are many types of power amplifiers on the market, ranging in price from a few hundred yuan to more than 10,000 yuan. In the eyes of laymen, exaggerated appearance, large size, high nominal power, and low price are value for money. In fact, some products use ordinary power amplifier integrated circuits, the power is very small; some use high-power transistors, easy to produce noise, especially static noise; some use fiber circuit boards, solder quality is inferior, easy to produce desolder or cold welding . As the use time prolongs, especially through changes in heat and vibration, the failure will manifest itself. Therefore, when choosing a power amplifier, be sure to know more and compare more.
Big is not necessarily good
The speaker is an important part of the sound system, which is equivalent to the human voice. The quality of the speaker directly affects the sound quality. Take the low-end coaxial speaker as an example. The middle tweeter is generally fake. Although there is a tweeter speaker cone, there is no wiring. Some speakers have larger magnets, and laymen think it's good. In fact, the size of the magnet is only one aspect. The quality of the magnet depends on its material. The good material is small, but the quality of the magnet made with it is very good. .
Car subwoofer adheres to scientific installation and reasonable configuration
The installation of car audio requires first-class installation technology and good after-sales service. Car audio is different from home audio. The harsh environment, temperature changes, vibration, dust, etc. will cause the car audio to malfunction. A properly designed and installed audio line will not affect other lines on the car and will not cause any noise to the sound system. The car audio is installed using ordinary wires, although the overall price is low, but the sound effect is poor. Moreover, there is a possibility of fire or malfunction at any time.
Third, the top ten misunderstandings of car audio modification
Misunderstanding 1: The more speakers on the car, the better, the better the sound effect
The more speakers, the better the sound. This is a big misunderstanding that many riders nowadays generally believe, but it is not. There is no proportional relationship between the number of speakers and the effect of sound quality in the sound. The number of speakers is fine rather than more. As long as the positions of the individual speakers are correct, the sound quality will naturally come out, and the speakers will only destroy the effect of the entire sound field.
Misunderstanding 2: According to the original parking space of the car, the modification does not leave traces.
Please tell us what is the modification? Change is the meaning of change and change. In particular, some cars now have no high-pitched sounds. Can we just change the car subwoofer? Obviously this is impossible. The most common modification method now is that in order to get a better sound field effect, the treble is usually cast on the A-pillar. Because the treble is very directional, and the penetration is weak, the treble is modified. It is necessary on the A-pillar. In fact, the current store is basically responsible for the owner of the mold, because the pair of A-pillars will take at least 6 hours, and the technical requirements are relatively high, and the modified store will make the sound system more A good performance is to recover only the material cost.
Myth #3: Wire is not worth the money
Wire is not worth it. I believe that this sentence has been modified by many shopkeepers. On the power line, as long as it is a slightly better line, it must be several hundred bundles, and only 10 to 20 meters. There are also speaker cables, audio cables, especially audio cables, dozens of cheap ones, hundreds of good ones, thousands of them, and thousands of them. These so-called "not worth the money" is that the wire does play a very important role in determining the sound quality of the sound. This is like a good sports car. If there is no good road, how can it run faster?
Myth 4: Tuning is free
Tuning is free, which is widely accepted by many car owners. And still take it for granted, why is this happening? The reason is very simple. The refit shop thinks that the sound is installed in itself. If you adjust the tone, you will not say that the money is not money. In fact, everyone knows that the car audio conversion tuning is the most difficult to learn, the most difficult to master. Skills. But why do you send this skill that you have mastered for free? That's right, it's for the sound system to work better. However, the owner did not know how much time and energy the tuner spent on this piece to have this skill. Therefore, if you have the master who will help you to tune for free in the future, buy 2 packs of cigarettes for the master.
Myth 5: How long does it take to install? 1 day? Time is too long
The modification time is too long, I believe this is the "excuses" that most people often encounter. In fact, the masters of the car audio modification industry are really too hard, because the time given by the owner is not enough, the modification process is not good, and there is no way to do it. Even the simplest wiring under the pressure of time constraints, I believe that the masters want to get better, it is not enough. Therefore, it is recommended that you give the master enough time to install the sound.
Myth 6: My original car's sound quality is very good, my original car horn sounds very good
As everyone knows, no matter what car, it sells the car itself, there is a comfortable Mercedes-Benz car that sells in the car, a BMW car that sells driving stimuli, a Volvo that sells safely, etc., but no car is saying The sound in the car is very good. Therefore, in order to have a good sound effect, modification is a must. So how do you modify it? Please change it according to your own personal needs. Because we are going to play the sound, not the sound. Don't listen to what people are blowing, know that no matter what you want, you only have to buy the right ones, not the expensive ones.
Misunderstanding 7: I listen to who and who said that the set of speakers sounds very good
I listen to who and who said that the sound quality of the speaker is very good, fatal modification misunderstanding. Everyone needs to know that we are equipped to listen to the sound, not to the one who listens. Anyone's understanding and feeling of sound is different. It is recommended that everyone no matter what speaker, amplifier, host. You have to know for yourself, you need to know what sound style you want to choose a good sound with your own style. This is like going to a restaurant for dinner. Do you think that the dishes that others like are delicious? The truth is actually very simple.
Myth 8: Why is there no sound in my bass?
Why is there no sound in my subwoofer? The most fear of professional car audio conversion is to hear this sentence. Tell everyone that there is no sound from pure bass. Do you know why there are different speaker units in the audio? Because each unit is responsible for different positions. The treble is responsible for the high frequency sound, the middle sound is responsible for the intermediate frequency, the middle and low sound is responsible for the low frequency and some intermediate frequency, and the subwoofer is responsible for some ultra low frequency sounds. Of course, there are more subdivisions in the frequency response. And a good sound, in the driver's seat can not hear the sound of the speaker behind, or even feel.
Misunderstanding 9: Can you not do sound insulation?
Can't you do sound insulation? Regarding the sound insulation, some people think that the effect is not great, and some people think it is necessary. And a good sound has a lot to do with soundproofing. In fact, everyone knows that the same set of speakers is good in the audition cabinet. How do you get into the car and change it completely? Tell everyone that the answer is the speaker problem. The sound is made to make the door panel close to the sound. Because the sound is emitted by vibration, the car is not soundproofed. When the sound is turned on, the horn vibrates, and the iron of the car is also vibrating. This will offset a lot of low frequency, and the effect of the sound will naturally be greatly reduced.
Myth #10: I want to use U disk to listen to songs
I want to use the U disk to listen to the song. I think this sentence is very understandable to the average person, but if it is in the eyes of an enthusiast, it will look very different. But listening to music, only you feel good. After all, the current plate is not cheap, although the sound quality of the U disk is almost the same, but more selective.
