It was originally due to lack of understanding of car audio, and even now some people think that the installation of car audio is a simple matter, this is not the case, car audio is through the installation of semi-finished products in order to become able to listen to the sound system, As the saying goes: one-third of seven equipment installation, the installation of car audio is an integrated technology and art, first of all to the car circuit and the circuit is well aware of sound, can not be affected by the installation of car audio performance, nor can the problems of insecurity brought about by motor vehicles, install the most sound The main purpose is to have sound effects, not only just for the sake of lower quality or the neglect of endless trouble to install. Of course, we all want to buy cheap equipment, brand name in the economy through the equipment with professional installation and debugging also play a good results, but do not share more than a pile of junk to buy equipment and stores to find small non-门脸professional installation, sound effects can be imagined, unfortunately disposed to listen to tasteless. installation of the low quality of the various failures often affect the useful life of the sound system, even in the car during the installation of structural damage, leaving the problems of insecurity. The second modification will need to spend money on the second, whether the accounting of it? Equipment with Car audio installation of the first session, that is, with equipment, with the installation of the process no matter how unreasonable to no avail. Not to buy brand-name products can be a good effect, with the principle should be that from the sound system as a whole to consider, for example, with some unreasonable: the host in general and the speaker quality indicators to choose high or high-end mainframe but the general speaker, so many lead to waste of resources. There is also the host power or the power amplifier power and speakers do not match, select the speaker not only depend on power depends on sensitivity, low sensitivity of the need to promote high-power. It is also important to choose the style of music in general divided into two schools, one is type sound: to listen to classical, symphonic-oriented. Another volume of hard-type: to听摇滚, disco-oriented, from the host - Amplifier - Speaker should be elected the same style, or great delight in naming. Some people think that bass called the Lung-lung Hu, sound is great, even to the point of distortion, this is wrong, the voice is not large or hours of the same distortion is really good, otherwise, can only be called noise. The quality of equipment is also critical, non-brand-name from the raw materials, performance, technology level, parameters are slightly lower, and some equipment as a result of the design and related devices, however, will have a natural, as the installation of a time bomb will be detonated at any time. Wire Wire is a sound system of an important part of its direct impact on the quality and quality of sound. Divided into signal lines, power lines and speaker lines, three lines the best selection of high anti-oxidation rate of high-conductive outer bags are PVC, PE, PP materials. Signal lines: double-layer shield should be used to enhance immunity, prevent access to the role of noise. Power cord: motor amplifier is used in low-voltage high-current, car audio and more carefully dedicated copper lines, the high impedance of small conductivity, the use of skin temperature of the high-flame-retardant anti-aging, it is necessary to power amplifier used in accordance with the size of current choice of diameter, too small diameter will have fever caused by heat loss, and even fire. If the current supply, the better the power play to see good results. Speaker line: the use of high and low temperature-resistant anti-aging, wire conductor material to titanium, silver, copper, Flexibility and strong skin, the wire can be different for each different sound quality performance. Insurance Turning to insurance, some people may think it is does not matter, and now tell you that the installation of the importance of insurance, if insurance is not the installation of power, but also installed a time bomb, the car is in motion the power cord if the skin has been omitted or grinding vehicle collisions caused by short circuit of the body, it will have a fire. Gold-plated insurance should be used to waterproof seat to prevent short-circuit corrosion and oxidation. Technology Installation process has two aspects: one is the wiring circuits must be reasonable, including the alignment does not affect the location of the original car lines, broken lines to prevent the cut together. Another aspect is modified without destroying the principle of the body, the equipment is installed with the same truck and the coordination of the overall layout and beautiful color. High-end audio system for vehicles to deal with sound-absorbing, that is, all aspects of the vehicle to reduce noise. Speaker is fixed firmly, making a fixed washer speaker. CD drive vibration direction is correct. The need to consider the impact of drilling should be the working conditions of vehicles such as tanks, lines, etc., or will cause a fire. Door should be reinforced to prevent resonance, for a better sound field position, it is necessary to produce reasonable door. Low-not just a speaker box can be issued on a good sound, low sound speaker unit according to the given data volume produced after the Cabinet as required. Line Sound system design should be reasonable, to avoid computer cabling and control systems, including power supply, signal and speaker line alignment arrangements, line by the thickness and location of cabling should be reasonable, the location of wiring will result in unreasonable noise, vehicle use of electrical appliances will also interfere with the sound system, audio car line will be used to generate electrical interference. Select the power contact must select the main trunk or the battery, if the wiring would have an unreasonable fire. Installation host, a single butterfly, butterflies and more, speakers, amplifier, equalizer and other equipment both at the technical requirements of each, such as: speaker of the phase, before and after about分频点choice. Subwoofer box design and construction, sub-damper combination to match, whether the composition is a reasonable response. Effect Sound effect is the result of the overall performance of the system, he is not only more than a reasonable match, the installation of technical and technological好就行done, and some modified the effect of bad radio, the sound field position, phase error, which should be in the audition process in the correction, or a direct impact on results. Finally, to the sound system to a high standard of testing, he also needed to fully understand the art of music enthusiasts, so that's as far as possible to restore the music sound perfect, position to deal with the volume balance, the balance is adjusted to deal with the co-ordination of the work point, the peak distortion adjustment distance from the location of processing, adjusting the sound to be the greatest potential to play equipment, so that by matching the equipment to achieve the best results.
