Six things to note before installing the audio 1. Safety: In the process of disassembly and assembly, the original car line cannot be damaged and cause a short circuit. When installing equipment, the line cannot be connected incorrectly, which will cause undesirable consequences. The installed equipment must have insurance measures, and should be protected in case of overcurrent, just like installing a time bomb, otherwise it is easy to cause fire. The audio circuit must not interfere with the computer and electronic devices in the car, otherwise it will malfunction. Only professionally trained personnel can install it to ensure safety. 2. Disassembly and assembly technology: in the process of refitting the audio, first of all, the original car audio should be removed. Whether it will be disassembled is the fundamental problem of modification. Because the screws cannot be seen on the surface of the instrument panel, it is necessary to pry up the decorative parts In order to see the screws, the disassembly operation process requires professional and strict, otherwise it is easy to disassemble. In the second step, if you need to wire or replace the speaker, you must disassemble the door panel, door edge, instrument panel, seat, decorative panel, etc. During the disassembly process, you must have special tools to keep the original intact, otherwise it will be unsightly And the seal is not good to produce noise. 3. Whether the product is qualified: There are many counterfeit brand-name equipments on the market, which must be clearly distinguished when buying, otherwise there will be endless troubles. Some low-cost equipment can not see the quality problem from the appearance, but the internal components are of inferior quality, and the circuit design does not meet the standards. The sound quality of this equipment is not good, not to mention, it is easy to malfunction. Even produce nature. It must be purchased at a store authorized by the manufacturer before it can be used with confidence. 4. What is the sound quality effect? If you do n’t buy a brand-name product, it will be nice. The brand-name manufacturers are also divided into high, medium and low grades. The grades you buy are not necessarily good. The most fundamental thing is that they must be matched by a professional system. . It is not a simple thing that several lines are connected casually, the sound field positioning and the phase can not be wrong, otherwise the effect is unimaginable. 5. Have you considered after-sales service: car audio is used in sports, and the environment is slightly evil: temperature, humidity, vibration, dust, etc., it is easy to cause various failures of the audio, maintenance, warranty and repair are very important issues. It is cheap to buy parallel imports, refurbishment, clearance products, stealing machines, etc. The warranty card is fake and there is no after-sales service. Once damaged, it requires maintenance fees or scrapping. Is it worth it? Now the equipment sold in specialty stores is not necessarily expensive, there are many cost-effective equipment, you can enjoy good after-sales service, why not do it. 6. Installation environment: Some small shop installations are operated in the open air. The staff's work clothes are very dirty. The sound is installed, but the interior of the car and the appearance of the car are dirty. It ’s a good thing to buy a new car for a stereo, but it brings a lot of bad consequences and it is a sad thing. The professional shop is operated indoors, and its advantages are 1, clean, and ensure that the car is clean inside and outside. 2. It is not affected by temperature. When the temperature is too low, it is easy to damage when disassembling plastic parts. 3. Not affected by the weather, it can work normally in windy and rainy weather. 4. Because of the lighting, it can work during the day and the dark. 5. Customers have a good lounge. The above is the technical difference between professional and non-professional, this is also the difference between the price of professional and non-professional, and ultimately it is a concept of value, whether to choose price or value. Do n’t think of installing audio as an easy task. It ’s not the case that the line connection sound sounds. Not only can the sound quality not be guaranteed, but also the bad factors and hidden dangers are in it, so it is emphasized that it must be installed in a professional store to be guaranteed.
