At present, the car audio market and attractive profit, many roadside mechanic shops do not have any professional training in the installation, the installation of car stereos are often a variety of failures, to the traffic safety hidden trouble. So, how to ease the selection of car audio and installation of scientific and effective maintenance of it? Recently, the reporter interviewed a number of shops and car audio industry, they remind you to proceed from the three chapters, you'll easily have a Heart of car audio. The face of the market an array of various brands of audio, it is easy to know what to do and how to choose sound fact there are some basic rules to follow. 1. According to their own tastes and affordability of the This is a clear understanding of their specific expenditure cost of the natural sound as good to have a good price. High-end luxury cars in general have a more professional high-level audio, which is better in Europe and the United States products, and its sound quality, sound more professional than the Japanese products. However, some well-known Japanese car audio brands have also launched a number of brands in Europe and America against fever. Although good, but prices are also really amazing, it is true it is expected to build its brand name to achieve the targets set out in the long term value and sustainable use. Mid-range audio equipment such as the selection of non-Japanese products go, it's brand in the professional car audio equipment accounted for 2 / 3. The ratio of price and performance value for money, and the completeness of functionality and appearance of the shape, decoration and crafts and so sophisticated, it is impossible to contend with Europe and the United States of products. 2. To get a clear understanding of whether it is really brand Now operating the market of car audio equipment business particularly, in order to avoid to buy a set of fake and shoddy products, the best in the business have to look at the brand audio equipment manufacturers license authorized by designated agents, the availability of after-sales service capacity and quality of three bags of commitment measures. Again excellent product, we can not guarantee that problems will not run. To address the conservation and car audio troubleshooting problems, attention should be paid when purchasing the selected sound audio brand of whether at the local after-sales service for professional certification maintenance points. Only equipped with a sophisticated audio brand of after-sales service in order to guarantee your car stereo in the event of failure of professional and convenient service. 3. The power to consider the capacity of host Selected as far as possible amplifier power than the speaker instructions. Due to a small amplifier in the long-term use of high-power output, it is easy to burn, but also lead to poor sound quality, distortion and other failures occur. For example: All the instructions of power sum of speakers for 100 watts, then the amplifier power to 100-l50-watt in between, in order to have a good match. 4. To learn more about the performance of speaker In the performance of high-grade difference between the host would not be significant differences between speakers on the staggering. A speaker at every turn marked with a few hundred watts of power, many are also confused by non-professionals, many speakers you are using the mark as long as 1 / 10 the power to try a few minutes, then I am afraid we must take a white smoke. 5. To listen sound, sound effects Listen, it is best to find a representative set of several songs, music, percussion, such as compact discs, a variety of sound effects on the differential degrees of innocence, and then determine whether or not to buy. 6. Keep product invoices, proof of maintenance In order to avoid unnecessary disputes, to protect their own interests at the same time, please note that products keep invoices, proof of maintenance. Installation of articles Four main points to be记牢 Attention should be paid to the proper installation of car audio, car audio is not like home stereos, are no longer in place after the mobile. Motor cars and the ever-changing road conditions, driving strong body vibration can cause jitter, the laser scanning head can not be normal, there jumpers or even damage the laser is first class. Therefore, the choice of which sound science shop to install it is very important. Industry recommendations: The best car audio shop in the same purchase and install, such problems are relatively easy to resolve. 1. Choice of large-scale specialty As far as possible large-scale car audio specialty choice, the general strength of the car audio store brand variety, well-known brands of car audio in general will choose strength, as the size of the store designated as its point-of-sale products. Here, the audio display is standardized and orderly, you can choose. 2. Audition equipment must be If you have basically a good car audio shop, then we must inquire whether they have professional audition audition equipment or vehicles, this is very important, because prior to the installation of car audio, listen only through professional devices Listen, in order to determine the choice of audio quality is good or bad. 3. Has got to be professional mixer Industry have a saying: car sound effects rather than bought, but by design installation and commissioning. Can be seen in the audio design installation and commissioning of the importance of the installation process. The same host, several speakers, a few wires, different installers construction, the outcome will be different. Specialty store owners in order to improve the listening environment, the vehicle for scientific installation design, installation of test equipment by virtue of professional conduct mixer, so that the effect of all the audio equipment to the best state of play. 4. Installers have qualification certificates Internationally renowned car audio of "Sony" and so on must be installed on staff assessment, the "car audio installation license" to induction. Construction of unqualified personnel to install equipment not only can not play its due effect, and may even undermine the relevance of the original equipment vehicle.   Article alerts Five major areas to be alert to Audio modifications, vehicle modification has gradually become a very important part. Number of visits to Beijing auto decoration store, regardless of the size of almost all converted to provide audio services, cheaper or easier to plan, many people will not find a store "to on as" a result, the majority of audio equipment out of is not "good." Where exactly the problem, may wish to listen to the advise of professionals:   1. Shoddy equipment installed There are many fake brands of audio equipment on the market, there are many non-brand-made hi-fi equipment, not only did not pass the technical evaluation and does not comply with state quality standards. Technology equipment such indicators is very low, the quality is very poor, and some machines have boot noise, play music when the background noise, which is poor signal to noise ratio is caused by poor circuit, but also the existence of security risks . There are a number of owners of motor vehicles for a lower price to install a sound, it seemed to install the equipment, but are basically inferior goods. Such devices are generally not technical indicators, and manufacturers have no origin, some posing as the United States, Japan's brand-name products. Combination of the use of these products sound system, there must be noise, music signals have distortion. Moreover, poor frequency response of these products in the music player must be defective, it is impossible to complete the performance of the music out, in particular, active subwoofer installed so that the overall sense of chaos in music, or even ambiguous. Good sound quality should be high, medium and low level is very clear, crystal clear water as一泓. How to identify the inferior audio equipment do? 1. To see whether the package is described in detail, place of production, manufacturers, specifications, etc.; 2. Whether the distribution of power of attorney; 3. The key is whether the issue of quality indicators to meet the equipment; 4. Acoustics into how the system.   2. The installation of equipment is low-grade products Although brand-name products, but each brand has a low, medium and high-grade equipment, the general low-grade equipment is very cheap prices, such as: low-end machine of the single platter CD of two pairs of low-grade speakers, more than 1000 yuan price only to see up are very receptive to brand-name products, but this is often easy to be abused a number of local businesses. Customers only see the brand-name products, we do not know is low-grade products, do not know does not match between devices, especially low-grade and some do not even have the speaker treble head, is generally used to support the tape drive low-power, power smaller, higher sensitivity, the volume will be slightly open when the distortion produced to support a good quality CD drive show it is very difficult, mainly high performance worse areas, hoarse, unpleasant, poor control of bass, and sometimes " Shooting, "the voice sent to the" head, head "of the. Therefore, when consumers must buy the integrated audio test of the indicators. 3. The equipment installed does not match between Rather than brand-name equipment we will be able to good effect, a customer is brand-name equipment installed, the installation of the 12 speakers, including three bass and three amplifiers. Volume is not opened, but also noise, low-size calculation of loudspeaker design has a margin of error, equipment with the most important thing is unreasonable, do not use equipment when, poor installation and debugging technology. It is precisely these reasons, the result of the overall system did not play a role. After re-installation after the match and, although the basic use of the original equipment, acoustics is an entirely new look. A good sound system configuration, not only with simple, but the main thing is to give full play to the role of each equipment, the potential of mining equipment. There is also the view, use the same brands of equipment like, here to talk about the way, what is the "fever"? Instead of using the best equipment is the "fever" should be using some good quality equipment, but the price is not necessarily expensive, with the adoption of reasonable, professional installation, debugging carefully so that the best equipment to play, more than equipment of their own values, even compared with the effect of brand-name equipment This is the "fever."   4. Poor installation techniques and processes Car audio is a semi-finished products, the need for trained professional car audio installation training of staff in order to guarantee the quality of sound. Some shops use the non-trained personnel, the general installation of the equipment is simple to connect, the sound field positioning error, phase error, the installation of power is not installed insurance fire. Installation speed, not the implementation of standardized processes, the use of wire poor, rough work, the result is poor sound quality, the high failure rate, short life of equipment. Just for the sake of the consequences of cheap installation is caused by shoddy work and inferior materials.     5. Debugging skill Generally engaged in car audio industry, lower educational level, car audio and even less theoretical knowledge, the installation is generally considered that the car audio is a simple matter, this is not the case, in order to install a good sound system, he should have a comprehensive the quality and theory, have the car circuit, electrical theory, acoustics, installation techniques, such as Music theory Knowledge . As the saying goes: "Road to listen to experts, listen to lively outsiders", some people think that the voices sound great, bass is a good weight and really good sound is not distorted when the volume and sound level of a sense of permeability, and bass is not scattered. Some installers do not even look at the use of equipment that we will not use the equipment, never heard a symphony of musical instruments such as the real voice, how to calibrate the sound? How can we listen to where the problem lies? How can a good effect of sound system, which requires testing is the audio enthusiast, in the mixer when the sound system will be adjusted to its best. Therefore, the installation of sound system debugging is an important part of the final.
