How to modify the car subwoofer

I wonder how many friends are dissatisfied with the original car acoustics? The treble is split, the alto is dry, and the bass is thin. If you are dead, listen to it. Listening to songs is not as good as wearing headphones. So, the following is how to modify the car subwoofer for everyone, hoping to help everyone.

1. Car audio modification scheme

If you search for the mainstream economical car audio improvement methods in the market at present, you will find that they are mainly concentrated in the following categories: replacing CD host, installing MP3 player, replacing MD head, MP3 converter, improving speakers, etc., and the investment varies from tens to hundreds of dollars.

improving CD headsets

nowadays, more and more cars are equipped with CD headsets when they leave the factory. however, cassette headsets still occupy a considerable share in the ranks of middle and low-end cars. Here, we will introduce a host improvement scheme of less than 1, yuan for those car owners who are not satisfied with the car audio system. If the speaker effect of your car is acceptable, you can consider changing a set of Alpine CDE-9841 headsets, and the approximate price on the market is around 93 yuan. Advantages: it can completely change the acoustic effect of the car, and the display panel of the nose is fine in workmanship. At present, the nose at this price can have such sound quality, which is also considered top grade. Disadvantages: There is no other function except playing CD.

add an MP3 player

if you count the most popular music playing equipment at present, it is a small and flexible MP3 player. Because of its small size, large capacity (a 256M MP3 can hold at least a hundred high-quality songs), it can also play edited songs according to its own habits, so it can be regarded as the hottest music gadget at present. In fact, it is not difficult to get MP3 in your pocket into the car. At present, many car audio manufacturers in China have introduced car CD hosts that can directly connect MP3. Just go to a professional audio modification shop to replace a new set of audio equipment, so that your car can readily accept MP3. For example, there is a kind of headstock called GoRun Geyun 611 in the market, and the market price is around 95 yuan. It belongs to an all-round car music player, which can be compatible with U disk, MP3 player, SD/MMC card, CD and MP3 format, and even I-POD can be eaten. Advantages: the audio convenience of the car is greatly improved. Disadvantages: the sound quality is naturally worse with more functions, and the line modification is more troublesome, so it needs to be modified in a professional audio shop.

change the MD head

for those car owners who like to make some noise by themselves, nothing is more suitable for them than a car MD. MD is a digital recording format CD-ROM, which enjoys high-quality repeated recording, greatly facilitating the compilation of personal music and other special purposes. Advantages: you can play recorded music, meetings, class records, live music, etc. in the car in time, and you can also edit all your favorite songs on an MD disc and enjoy digital sound quality. Disadvantages: high price, only suitable for a few enthusiasts.

Add MP3 converter

For consumers who have both MP3 players and CD headsets installed, it is the greatest wish of car owners to connect them. Don't worry, someone saw the huge market long ago, so a kind of equipment called MP3 in-car audio converter (also called receiver) came into being. Its working principle is to convert the sound source of MP3 into FM signal, and then receive it through the radio of the host computer in the car. Although the sound quality is not as good as that of MP3 live broadcast, at least there is no need to bother to modify the lines in the car. Advantages: Small investment. Only a few tens of dollars can solve the conversion from MP3 to in-car stereo. Disadvantages: poor sound quality. It's similar to listening to the radio.

improvement of speakers

for those sound systems that have been well matched in the original car, the car owners don't have to fiddle with electronic equipment any more. If you only want to improve the sound quality, you can selectively replace some speakers in the car or install power amplifiers. However, this needs to be tailored to different cars in a professional audio shop. If the owner is a pop music lover, a pair of 6×9 woofers is very necessary. Generally, the price of a 6×9-inch speaker with acceptable sound quality on the market is about 5 yuan. If you are a car owner who prefers rock music, you can install a subwoofer, and 3 yuan can get it with about money. The movement after the change is quite big. Advantages: low investment and obvious effect. Disadvantages: after all, it has not been matched by the system, so there will be concerns about the stability of use. In a word, the sound modification in the car varies from person to person and from money, and sometimes a small amount of money can bring about great changes.

2. Precautions for refitting car stereo

One day not long ago, a car burned beyond recognition was dragged into the auto repair shop. The owner said regretfully that this was the result of short circuit caused by his own modification of car stereo. He also revealed that the car stereo was originally installed in a car wash shop. Recently, car fires caused by audio circuit problems like this have been on the rise.

Experts remind consumers not to buy car stereos blindly, but to ask, read, listen and learn more to avoid being fooled. You must go to a professional institution to modify the car stereo.

Let me look at you more

In order to attract customers and promote products, merchants often pass off domestic audio equipment as imported products. Some dealers claim that their products are produced in the United States and Britain, but consumers can find flaws as long as they pay attention. For example, see if there is a place of origin and Chinese words on the package, and if there is an import license. Some manufacturers copy Sony, Pioneer and other famous brand products to confuse the real with the fake. In this regard, we should carefully observe whether the manufacturing process of these products is rough. In addition, checking the sales license of the manufacturer, listening to the sound quality and checking the serial number of the product on the website of the audio manufacturer are also simple ways for ordinary consumers to identify the authenticity of the product.

Being in a hurry often doesn't make you wise.

Some young people, who are high-minded, often want to decorate the car at once after buying their first car, but in fact, being in a hurry may not make you wise. This is easy to take advantage of the illegal car dealers who sell cars and the owners of car stereos. They colluded with each other and took advantage of consumers' lack of understanding of car stereos to deceive car owners. They install products with inferior quality and high price, and charge high price difference for inferior quality. In this way, car owners' friends can not only enjoy good music, but also cause a series of joint quality problems. Moreover, once a problem occurs, it is a difficult problem for the owner to sort out the responsibilities and claims here.

think twice before you act

when buying a car stereo, don't make a blind decision, think twice before you act. Car audio is a semi-finished product. Only professional design and configuration, professional installation and debugging can achieve an ideal state. For the choice of equipment, the car mainly knows the truth that the sound effect can exceed the value of the equipment itself by using general equipment and reasonable collocation and debugging. Therefore, for ordinary car owners, it is not necessary to deliberately pursue all the devices from power amplifier to subwoofer, and the principle of choosing car stereo is to make the best use of it.

There is a lot of water in the speaker amplifier

Some merchants take advantage of the customer's sensitivity to the price of the mainframe to minimize the price of the mainframe, or even sell it at a loss, and then configure low-grade power amplifiers and speakers for customers to obtain high profits.

You can't have parallel stereos

Now there are some "parallel products" circulating in the market. Some car owners think that parallel imports are hybrids and have certain advantages. This idea is wrong. When buying car stereos, you can't choose parallel imports. First of all, it is not allowed by national laws. Secondly, it has no warranty, and once it is damaged, it will have to pay for itself. The format of some parallel imports is different from the current broadcasting system in China, and the radio can not be used normally; In addition, the service life of repaired products and refurbished machines is also very short, so it is difficult to guarantee the quality.

You need an invoice for installing the stereo

Before installing the car stereo, the car owner's friends should determine whether the seller has the professional installation equipment and after-sales service ability through their own observation, and if necessary, they can directly ask the merchant to check whether there is a sales authorization certificate, business license and professional installation training certificate approved by the manufacturer, which can also protect their rights and interests from infringement to a certain extent. Products must have a formal warranty card, fill in the sales date, and affix the' valid seal' of the sales unit. Consumers should also carefully read the warranty terms, confirm the warranty time and place, and ask for an invoice.

"It looks beautiful" Don't be credulous

Some people only pay attention to the appearance when buying a host, and choose a host that looks beautiful, regardless of the internal quality and performance of the sound itself. If the panel is to be beautifully made, the production cost will inevitably increase and the sales price will also increase. In addition, if the audio panel has balanced graphics and high brightness display, it will also affect the driver's observation of the road surface when driving at night. If you want to install a cheap and economical sound system, you can't choose this flashy model. Some models of good brands, although simple in appearance, are in harmony with the dashboard of the car, and the expressive force and sound quality of music are first-class.

Volume and power are not the only factors

Some young people feel that they are not strong enough to use the host to push the speakers, so they need to install a power amplifier. There are many kinds of power amplifiers in the market, and the price ranges from several hundred yuan to ten thousand yuan. In the eyes of laymen, exaggerated appearance, huge volume, high nominal power and low price are value for money. In fact, some products use ordinary power amplifier integrated circuits, and the power is very small; Some use high-power transistors, which are prone to noise, especially static noise; Some use fiber circuit boards, and the quality of solder is poor, which is easy to cause desoldering or virtual soldering. With the extension of service time, especially after cold and hot changes and vibration, faults will appear. Therefore, when choosing a power amplifier, we must know more and compare more.

A big speaker is not necessarily good

A speaker is an important part of a sound system, which is equivalent to a person's voice. The quality of the speaker directly affects the sound quality. Take the low-grade coaxial speakers as an example. The tweeter in the middle is generally fake. Although there is a tweeter cone, there is no wiring. Some speakers have large magnets, which laymen think are good, but in fact, the size of the magnet is only one aspect, and the quality of the magnet depends on its material. A good material has a small volume, but the quality of the magnet made of it is very good.

car subwoofer should be installed scientifically and configured reasonably

car stereo installation requires first-class installation technology and good after-sales service. Car stereos are different from home stereos, and the bad use environment, temperature change, vibration, dust, etc. will cause car stereos to malfunction. After reasonable design and installation, the audio circuit will not affect other circuits in the car and will not produce any noise to the audio system. Using ordinary wires to install car audio, although the overall price is low, the audio effect is poor. Moreover, fire or failure may occur at any time.

Third, the top ten misunderstandings of car audio modification

Myth 1: The more speakers in the car, the better the sound effect

The more speakers, the better the sound effect. This is a big misunderstanding that many riders generally think now, but it is not. There is no equal relationship between the number of speakers and the effect of sound quality in acoustics. The number of speakers is fine, not many. As long as the positions of each speaker unit are right, the sound quality will naturally come out, and more speakers will only destroy the whole effect of sound stage.

Myth 2: Install according to the original parking space of the car, leaving no trace of modification

Please distinguish what modification is? To change means to change, to change. Especially now, some cars don't have treble. Should we just change the subwoofer for such cars? Obviously, this is impossible. Now the most commonly used modification method is that in order to get better sound stage effect, the treble is usually inverted on the A-pillar, because the treble has strong directivity and weak penetration, so it is necessary to modify the treble on the A-pillar. In fact, the current shop owners basically do the duty for the owner of the car, because it takes at least 6 hours to mold a pair of A-pillars, and the technical requirements are relatively high. In order to make the sound system work better, the modified shop owners only recover some material costs.

Myth 3: Wire rod is worthless

Wire rod is worthless. I believe that this sentence has been heard by many refitting shops. On the power cord, as long as it is a little better, it will cost hundreds of dollars in a bundle, and it is only 1 to 2 meters. There are also speaker cables, audio cables, especially audio cables. There are dozens of cheap ones, hundreds of good ones, thousands of them and tens of thousands of them. But these so-called "worthless" wires do play a very important role in determining the sound quality of audio. This is like a good sports car. If there is no good road, how can it run fast?

Myth 4: Tuning is free

Tuning is free, which is generally believed by many car owners. And I still take it for granted. Why did this happen? The reason is very simple. The refitting shops think that the stereo is installed here, so it is not necessary to say that it is not expensive to turn down the sound. In fact, as we all know, car stereo modification and tuning is the most difficult skill to learn and master. But why does everyone give away such skills for free? Yes, it is to make the sound system work better. But the owner doesn't know how much time and energy Andhadhun spent on this piece to have this kind of foundation. Therefore, if there is a master who will help you tune for free in the future, buy 2 packs of cigarettes for that master.

myth 5: how long does it take to install? A day? Time is too long

It takes too long to refit, and I believe this is also the most common "excuse". In fact, it is really too hard to be a master in the car audio modification industry, because the time given by the owner is not enough, and the modification process can't be done well and can't be done. Even the simplest wiring is under the pressure of tight time, and I believe that the masters will be unable to do it well. Therefore, it is recommended that you install the stereo and give the masters as much time as possible.

Myth 6: My original car's main engine has a good sound quality, and my original car's horn has a good sound quality.

As we all know, no matter what kind of car, it sells the car itself, including a comfortable Mercedes-Benz, a BMW with exciting driving, a Volvo with safe driving, etc., but none of them say that the sound inside the car is good. Therefore, in order to achieve good acoustics, modification is necessary. So how to modify it, please change it according to your own personal needs. Because we want to play with the stereo, not be played by it. Never listen to anyone's nonsense, you should know that no matter what you buy, you should only buy the right one, not the expensive one.

Myth 7: I heard someone say that the sound quality of that set of speakers is very good

I heard someone say that the sound quality of that set of speakers is very good, which is a fatal misunderstanding. Everyone should know that we installed the stereo for listening to ourselves, not for listening to that person. Everyone's understanding and feelings about sound are different. I suggest that no matter what speakers, amplifiers, hosts.
