There are a group of music enthusiasts active among car users. Their car is a mobile concert hall on the road, but do you know the six questions you need to think about before modifying the audio?
1. Safety: During the disassembly and assembly process, the original car circuit cannot be damaged or short-circuited. When installing the equipment, the circuit can not be connected incorrectly, and the wrong connection will cause adverse consequences. The installed equipment must have insurance measures, otherwise it is prone to fire. The audio line must not interfere with the computer and electronic devices in the car, otherwise it will malfunction. It must be installed by professionally trained personnel to ensure safety.
2. Disassembly and assembly technology: in the process of refitting the audio, first remove the original car audio. Whether the disassembly and assembly are proficient is the fundamental problem of the modification. Because the screws are not visible on the surface of the instrument panel, it is necessary to pry off the decorative parts. Only the screws can be seen, the disassembly operation process requires professional and strict, otherwise it is easy to be broken. In the second step, you need to wire and replace speakers, you must disassemble the door panel, door side, instrument panel, seat, decorative panel, etc. During the disassembly and assembly process, you must have special tools and keep the original intact, otherwise it will cause malfunction. Issues such as aesthetics and noise.
3. Whether the product is qualified: There are many counterfeit brand-name equipment on the market now, so you must distinguish it when you buy it, otherwise there will be endless troubles. Some low-priced equipment does not show quality problems from the appearance, but the internal components are of poor quality, and the circuit design does not meet the standards. The sound quality of this equipment is not good, and it is prone to failure. Even spontaneous combustion occurs. You must go to the store authorized by the manufacturer to buy it before you can use it with confidence.
4. What is the sound quality effect: It is not necessarily good to buy famous brand products. The varieties of famous brand factories are also divided into high, medium and low grades. The high-grade ones may not be good. Good results. It’s not just a matter of just connecting a few lines randomly. The sound field positioning and phase cannot be wrong, otherwise the effect will be unimaginable.
5. Have you taken into account after-sales service? Car audio is used in sports and the environment is a bit harsh. Such as: temperature, humidity, vibration, dust, etc., it is easy to cause various failures of the audio, maintenance, warranty and repair are very important issues. Buy parallel imports, refurbished machines, clearance products, stolen machines, etc. at a low price. The warranty card is fake and there is no after-sales service. If it is damaged, it needs repair fees or scrapping, which is not worth it. Now the equipment sold in specialty stores is not necessarily expensive. There are many cost-effective equipment that can enjoy good after-sales service. Why not do it.
6. Installation environment: some small shops are installed in the open air, the staff’s work clothes are dirty, and the stereo is installed, but the interior and exterior of the car are dirty. It is a good thing to buy a new car and change the audio, but it brings many bad consequences, which is a painful thing. The professional shop is operated indoors, and its advantages are: (1) Clean, to ensure that the inside and outside of the car are clean. (2) It is not affected by temperature, and the plastic parts are easily damaged when the temperature is too low. (3) Not affected by the weather, it can work normally in wind and rain. (4) Because of the lighting, it can work during the day and in the dark. (5) Customers have a good lounge.
