1. Three Steps to Car Audio Tuning
First of all, the most important thing to note about tuning your car audio is - what style of music you really like! As we all know, today's music style can be described as blossoming, what rock, DJ, pop, acoustic music, vocals and so on have a lot of audience. Because of the specificity of music, car audio manufacturers will produce different types of speakers for different music styles. So, only if you are clear about your favorite style of music, you can choose the best car stereo for you.
Then there is your budget, both how much money you are going to spend on your car stereo! As the old saying goes, you should wear shoes with big feet, and the same is true for car stereo modification. According to their own actual situation, to car audio modification of the car, one to meet their own needs, the second did not give themselves what the so-called "three points of the equipment, seven points of the technology," the choice of car audio modification store: a dish, the average person may be done more ordinary, and skillful chef can be done! "The main reason for this is that the chef has the ability to cook! The main reason for this is that the chef has a high level of skill in cooking. Car audio modification is the same, the same car audio products, different master installation, will cause different sound effects. It is important to choose a good car audio tuning store!
2. Audio Modification Taboos
1, take advantage of the psychology of cheap According to statistics, the general cost of modifying the sound of the audio ranges from about 1,000 to 7,000 yuan. So when it comes to modifying car audio, there are a lot of car owners who confess that they are not quasi-professional audio enthusiasts, so they just want to spend a little money to improve the music environment and the music sense on it. So when choosing a car audio tuning store, you tend to "choose what's cheap" and forget all about the "one price, one product" principle, resulting in the final effect of the modification
2, the wrong estimation of the professionalism of the car tuning store you choose. The first thing you need to pay attention to is the circuit problem, in the car audio modification and repair must be to the car audio modification store with professional experience, because, unprofessional modification store is likely to damage the original car circuit in the modification process, so not only the sound effect has not been improved, there may affect the vehicle warranty and a series of after-sales service problems, in the cloth, must do a separate cloth power lines, audio lines, signal lines, and also to do a separate cloth power lines, audio lines, signal lines, and also to do a separate cloth power lines, audio lines, signal lines, and also to do a separate cloth power lines, audio lines, signal lines. In the wiring, be sure to do a separate cloth power lines, audio lines, signal lines, and lines between the good shielding and protection, to do a foolproof. But for car owners, it is difficult to correctly determine whether a car tuning store is professional. The best way to check in advance on the recommendations and evaluation of the car tuning stores around the world, so that you have a clear idea of what to do to save unnecessary trouble.
3, ignoring the upgrade space of audio modification, it is understood that many car owners in the car audio modification, often ignoring the future upgrade space. The audio modification generally has a gradual process, the general order is the first speaker, and then upgrade the efficacy, and then increase the subwoofer, and finally replace the host. But the owners had better be able to reserve some upgrade space, if you want to upgrade the strong resolution of the host in the future, you can achieve the sound quality of HIFI effect. If you don't anticipate the upgrade space in the future, you will encounter the upgrade bottleneck when you have the need to upgrade.
4, when people judge a professional audio good and bad sound system, both frequency response as the evaluation of the main target curve smoothness.
Want to improve the sound quality of the car audio system? First start from the sound source. In the establishment of the audio system, the matching of individual equipment should be kept in the same style basically, otherwise it may cause the appearance, function, use, indicators and other aspects of the disharmony.
●To CD, MD, not VCD, MP3
If only used to play the sound, the host is still the choice of CD, MD or DVD. VCD's sound quality is poorer, it is best not to use; MP3 belongs to the compressed format, although the increase in the sound quality of the processing circuitry, but the quality of sound is still inferior to the CD; DVD's sound quality is close to the CD, but the overall comparison is still not as good as the CD; MD's sound quality is not much different from CD, but the sound is slightly harder.
●To "original flavor", do not equalizer
The host should be used to the signal without any modification of the model, that is, the so-called "original flavor". After the signal has been modified, its waveform is distorted, so the music played out is not ideal.
"Original" host preferably without graphic equalizer, field effects (such as theater, square, studio, etc.). After the modification of the field effect, the original signal will produce changes, losing the original sound quality.
●To 24bit, not 1bit
Choose the model to see the frequency response indicators, without any additional modification of the sound quality features. 20bit and 24bit high resolution in order to make the music to be fully realized. Ordinary audio is mostly 1bit.
●To high power, not distortion
If you use the host to drive the speakers directly, choose a high output power. The host output power is usually 4 × 50W, mainly to reduce distortion.
If you use the host's pre-output, to choose a high output level, the purpose is to improve the signal-to-noise ratio, the output level is generally 2V, the best choice of 4V output. By the way, the CD record should be used to choose genuine, with the disk printed on the surface of the "DDD" the best, this CD record produced by the sound quality is good.
3. How to configure audio modification
Selecting the real car with a good sound needs to be strictly controlled in the purchase of car audio or other automotive electronic goods, most consumers the first factor to consider is mostly the budget, but to be Note that the price and the function and characteristics of the goods are absolutely related to the consideration of the time to think more clearly first, what their needs are, so that the selection makes sense.
Consumers who pay attention will find that the function is almost the same audio, car use will often be more expensive than home, the reason is that all the equipment used in the car basically to be able to withstand high temperatures, vibration, and therefore the specifications on the requirements of the more stringent. At the same time, the most important thing is that the use of equipment in the car to minimize the interference of driving, do not be noisy, in order to operate the equipment and affect the safety of driving.
Car stereo since it is a kind of audio, belonging to the points of audio purchase is generally similar, is to see the individual on the sound quality, tone requirements. Here especially to mention is because of the use in the car and the point of difference.
Car audio to focus on safety
First of all, the security considerations mentioned earlier, to consider whether the operation of the goods are in the hands of the place, whether they are easy to learn, easy to remember, there is no special design for the safety of driving. For example, some car audio hosts can be paired with a control lever called the safety lever control, the principle of the design is to control the main functions of the audio control is concentrated in a control lever, through the touch of the hand can be operated, such as in the control of windshield wipers, lights, etc., do not have to be distracted by the eyes to see.
Secondly, the listening environment in the car is very different from home, in addition to the aforementioned high temperature, vibration, there will be noise coming from all directions, these noises will interfere with the music of the low-frequency band, is generally retrofitted with an enlarger to overcome this problem. Amplifier to be based on the size of the entire audio system? Number of speakers, speaker size and frequency response, etc.? Consider the number of sound channels and output power. Output exceeding the maximum output power of the amplifier may cause the amplifier to burn out. In that case, is it true that more output power is better? In fact, the space inside the car is not as large as at home, do not have to be superstitious high power output, as long as enough to use. In addition, the higher the output power, the higher the price.
4. Car audio soundproofing steps
Specifically, the system soundproofing project is generally through the vibration damping, noise reduction, sealing three steps to complete.
First of all, the four doors, trunk, floor, engine compartment and roof damping treatment;
The implementation of damping treatment, there is a primary and secondary: the first is the door and trunk, because the vast majority of the noise is through the car's suspension system, trunk, chassis, doors, and other parts of the car into the car; the next is the floor and the engine compartment; and finally, the roof.
Finally, seal the interior of the car.
When sealing the car, don't over-seal it, because the car body sealing project is the basic project to solve the problem of noise transmission from the outside to the inside, it should be a good sealing of the car body, so that the air pressure inside the car to maintain a balance, or else, over-sealing can cause the lack of oxygen inside the car, which will bring danger to your body.
Because of the car noise is not easy to focus on the management, therefore, the quality of construction products and construction technology has high requirements, in general, professional acoustic products are better sound insulation products, which includes soundproof pads and sound-absorbing cotton two kinds of materials, soundproof pads paste in the body of the vibration of the parts, while the sound-absorbing cotton can absorb vibration damping adhesive can not cope with the noise of the noise generated by the vibration. Usually, the implementation of the car sound insulation project, need to paste a layer of sound insulation pad and a layer of sound-absorbing cotton.
After the general soundproofing project, the noise can be reduced by 2-3 decibels, good materials can make the car noise down 5-8 decibels, in the best case, can be reduced by 13 decibels, if the construction personnel told you can reduce 20 decibels, or even more, then you should pay attention to is not being fooled.
Additionally, just doing a firewall is not going to achieve a better soundproofing purpose.
About car audio car sound insulation
Car sound insulation products originated in the late 1980s by the United States a group of car audio enthusiasts in order to be able to better enjoy the fun brought by the car stereo and the development of these products can reduce the driving process of the noise inside the car, but also can enhance the sound pressure and tone of the car stereo. So the car sound insulation was originally created for the real love of the car hedonists, the purpose is to let more car owners to get the perfect sublimation of life to enjoy more wonderful driving pleasure. If you don't pay attention to soundproofing after car audio modification, then the owner's enjoyment may bring great disturbance to the passers-by.
5. The Five Myths of Car Audio
The motivation for consumers to decide to buy a certain product depends on three elements, one is the quality, the second is the price, and the third is the brand. Car audio modification of good and bad, good and bad, in addition to the quality of the product, price, brand factors, but also focus on the modification technology. However, some car owners do not quite understand, and audio modification store is not properly guided, some stores instead of misleading, so you need to be vigilant. [1]?
Misunderstanding one:
To very dazzling product appearance and packaging to attract the attention of car owners and consumers. For example, I have seen a car amplifier, packaging is very exaggerated. Wooden box outsourcing leather, open the box lined with scarlet velvet, a production, printing beautiful rectangular similar to the cookie tin box, open, see is indeed placed on the amplifier on a pair of high-count knitted snow-white gloves, the following is the amplifier with a blue velvet bag. This packaging makes people feel that the product is very high-grade. Manufacturers in the product up and down so much effort, is nothing more than creating gimmicks, Bo a car owner consumer's first impression, the price is naturally expensive, however, the quality of it ------
Misunderstanding two:
Price has become a measure of the quality of the car audio yardstick, the existence of two extremes, one is overly pursuing high-priced products, that the selection of the more expensive the better, that is, the reason for the price is expensive; another is that the more the cheaper the better, that the audio modification, the better. The cheaper the better, that audio modification is nothing more than a change in the head, speakers, the selected replacement the cheaper the better. In fact, these two ideas are vanity. The former will show off, I modified car audio, how much money spent, high grade; the latter will say when asked, my car did car audio modification, seem to have taste.
Myth three:
The foreign brand complex lingers. Because of the usual consumer goods have foreign brand complex, so the car modified audio do not pretend to understand, that foreign brands must be better than domestic brands. Domestic brands also have excellent products, many foreign brands are well-known brands of Chinese small factories to use their brands to fake. So the most important thing in the mixed market when selecting products is to audition. Everyone's understanding of music is different, only audition to determine whether the speakers are in line with your sense of hearing.
Myth 4:
The more power the better, install a large-caliber subwoofer and drive the amplifier is to achieve the bass effect of the external driving force. Do not know, in the bass speaker quality is not good, drive amplifier quality is poor in the case, distortion of the bass will become noise. So "fried" as a bass reflects an aspect of impatience, and again, sitting in the car every day "fried", your ears can stand such torture? In fact, with age, the human mind will become more and more calm, listening to the most may still be light music or vocal singing.
Myth 5:
Not focusing on the modification technology, there is a seven-point equipment, three-point technology. Car audio is different from home audio, buy home to connect the line on the OK. Then good host, speakers, amplifiers without good tuning technology with excellent auxiliary materials for matching, installation, debugging, and then debugging (new equipment modification is completed must be boiled for a period of time and then back to the store to re-tune), is equal to twice the effort and half the effort, due to the quality of the audio did not play out is not very depressing ah?
Examples of the above car audio modification of the misunderstanding of all kinds, is to illustrate, car audio modification is also equipment, technology, the perfect combination of artistic cultivation. To be able to integrate them reasonably, like a complete and beautiful picture, like a complete stage, show in front of you, which is a real enjoyment, in order to achieve value for money. Car sound reform, vanity should not be, quality is the hard truth.
