Car audio installation standards

There are a lot of drivers: car audio and home audio system? we go ask a very urban car audio master of Qin, he did not hesitate to answer: the biggest difference is the car audio is a technology requires high professionalism of more complex installation process.

Then the car audio installation standards? how can I install a qualified estate car audio conversion is a new industry. Countries now have a comprehensive unified standards in car audio industry for over a decade of Qin mentors that in more developed areas of the industry's professionals in the actual operation, the summary presented some industry or in-store construction requirements.

1. line process standards. Line requirement is immunity and safety. All wire must have resistance to burn, signal cables must have shielding, the amplifier's power cord to the rough enough. The power cable through the metal to be protected, all power cords must be set with the waves. Audio portion of the power supply and its various components should have a separate insurance policy designed to ensure sound of electrical safety. Speaker line should stay away from Ming line and the main power cable, as a last resort, that also should cross-vertical alignment, in particular the signal line, host, and CD case connection control cable. Host and power amplifier line, strictly to prevent mutual interference out noise. Another point is the General Audio shop easily neglected issues: the line connection point should be securely connected, best use of welding, such a connection to the power loss and the signal attenuation is reduced to a minimum. Power cord and put header should use the appropriate line connection, usually in the nose and welding or clamps attached before swiping Tin treatment.

Second, Assembly technology standard. decoration This standard general requirements maintain all original vehicle. To increase foreign decorations, its style as far as possible, consistent with the original car .A column treble Tsai and door panels of the foreskin painting etc, and the car's color and design in harmony.

3. speaker installation standards. Speaker setup the general requirement is firm, vibration-proof, installation speaker resonance when it is best to install sealing cushions. Instrument panel speakers most easy to produce small resonance. Bass speaker cabinet should choose about quality education 18MM good density Board, but also in the box is equipped with an appropriate amount of sound-absorbing materials, of course, this loudspeaker installation requirements will increase certain artificial time-consuming and material costs, when the shop owner to receive installation time, jeepers were advised to understand, if you do not charge a Setup, you should be careful to check the quality.

4. listen to the sound. Is there a problem with sound installation, you can listen to check. 1. auto start, press loud Horn, listen to speaker is there jamming .2. throttle, listen to the engine and generator for noise interference. 3. set the volume to "0" to hear high-pitched Tsai has current sound. 4. set the volume to two-thirds, to hear in loud speaker installation under pressure, a solid, there is no resonance phenomena. 5. put a professional auditions for the disk to determine the installation phase for errors, or to use phase meter testing. After installing the audio sound effects?

V. consolidated, unique detection "instrument" is my ears, audition and after installation. Install contrasting audition before and after, is the only way. "The suitable is good sound" is the city of Qin master truthfully say!

Facelift car audio not illusion
Original car audio due to consider the cost of the vehicle, in the basic configuration is generally, at the sound quality is also a general like grades, just the sound of this feature, for sound and listen to the acoustic field positioning is not so much to consider, and some models only for overall aesthetic, speaker of the installation location doesn't sound principles, the use of speakers is just general indicators, especially the Middle cars switched stereo highest chance, however, replacement after repentance of many, this is why? car is equipped with low quality cars original is power small cassette or CD host, speakers and not with the treble level of the head, hair is not clear sound, the sound quality will definitely not boring. When switched larger power CD host, with treble trumpet, even the ordinary CD player and General trumpet sounds than the original car's effect is good, but it is also an illusion. Although the ratio of the original car, but has not reached you invest for the best results. This requires a professional staff, reasonable matching equipment, in order to get price good sound system. Most people know enough for car audio, mistakenly think: my car is not luxury, buy cheaper sound. It is with this in mind, so that no formal businesses drill loopholes, improper configuration of some high quality and low profit, just swap of equipment when you feel is better than the previous, but listening to a few days, problems arose, particularly professional audio shop installation of same price difference than, more than the sound quality, installation technology, process, testing, use of the wire is the gap, the failure rate is high, which also determines the life of the equipment used. As the car space location restrictions, car amplifier bass to achieve placement stability and good heat dissipation, the best option, of course, is the car's trunk. This inevitably leads to two questions, first, how to minimize the equipment on the trunk of the volume occupied and function, the second is how to minimize damage to automobile trim, minimize audio signal transmission loss. Car sound effects inevitably affected by the engine sound, external influences such as air sound interference which focuses on bass and bass parts, auto install bass speaker has become particularly necessary. Just loaded on fake bass, feeling better than before, but heard some time you will feel the bass ambiguous, listening after chest, head hair mask. This is because in the distortion of State becomes noise, this noise can damage the brain against the body. Here's advice to swap stereo friends, not just for the sake of cheap sell junk in the future discovered problems then adapted, will abolish many equipment and wasting money. Do not assume that a professional shop price necessarily expensive, both have fried potatoes and lobster. However, there is taste of taste, even the low package, equipment quality assured, and access to state-of-the-art installation technology and good after-sales service, there will be a premium feel.

It is well known that the human ear is acceptedThe sound from the front, in the car this narrow space, arrange speakers so that people in the front seat can be perceived from the windshield clear sound, not from feet to the rear seat is also possible to feel the sound from the front instead of behind the ear. In addition because the distance from the left and right speakers, to enable different biases seat area can feel good music balance also needs to be set-up for different speakers to correct distance deviation. From this perspective, the difficulty of car audio positioning than home audio. Thus, car audio design installation requires professional technology. According to experts, a good car audio installation, to achieve the four requirements: a be music matching set reasonable, and vehicle performance, space and owner requirements expedient, in layout to the best without damaging the interior trim. The second is the accurate positioning of sound field with good acoustic image effects, sound field construction and sense of space, sound of stereo, spectral curve continuous smooth, can maintain its range from bass to treble integrity. The third is the appropriate sound pressure, a high-quality car audio when the sound reaches 130 decibels above can still maintain the sound is distorted, restore power to get the maximum play; the fourth is installed horizontally, this includes Terminal line design, decoration and the original car's harmony, PA thermal design and overall aesthetic design. Design and installation of car audio, has the specialized knowledge of course do everything according to your ideas, if you grasp of matching, or professional knowledge, professional design and installation. By contrast, some non-specialized stores province some money to buy audio please mechanic indiscriminately install, look for professional audio shop plan a professional level.
