1. Safety: During the disassembly and assembly process, the original vehicle wiring should not be damaged or cause short circuits. When installing equipment, the wiring should not be connected incorrectly, as incorrect connections can lead to adverse consequences. The installed equipment should have insurance measures in place, otherwise it is prone to fire. The car audio circuit should not interfere with the computer and electronic devices in the car, otherwise malfunctions may occur. Professional trained personnel are required for installation to ensure safety.
2. Disassembly and assembly skills: In the process of modifying a car audio system, the first step is to remove the original audio system. Whether the disassembly and assembly is proficient is the fundamental issue of the modification, because the screws cannot be seen on the surface of the dashboard now, so it is necessary to pry open the decorative components to see the screws. The disassembly process requires professionalism and strict procedures, otherwise it is easy to disassemble and damage. The second step is to install wiring and replace speakers, which requires disassembling and assembling door panels, door edges, instrument panels, seats, decorative panels, etc. Special tools should be available during the disassembly process, and the original parts should be kept intact, otherwise it may cause problems such as unsightness and noise.
3. Is the product qualified: There are many counterfeit branded equipment on the market now, and it is important to distinguish them when purchasing, otherwise there will be endless troubles ahead. Some low-priced equipment may not have obvious quality issues from the appearance, but the internal components are of inferior quality and the circuit design does not meet the standards. This type of equipment has excellent sound quality and is prone to malfunctions and even self ignition. Be sure to purchase from the authorized store of the manufacturer in order to use it with confidence.
4. What is the effect of sound quality: It's not just about buying branded products that will always sound good. Brands also have high, medium, and low grade varieties, and buying high-end ones may not necessarily sound good. Ultimately, it requires professional personnel to systematically coordinate, install, and debug in order to achieve good results. It's not just a matter of connecting a few lines casually, the sound field positioning and phase should not be wrong, otherwise the effect will be unimaginable.
5. Have you considered after-sales service? The car audio system is used during sports and the environment is rough. For example, temperature, humidity, vibration, dust, etc. can easily cause various malfunctions in the audio system. Maintenance, warranty, and repair are important issues. Cheap purchase of substandard goods, refurbished machines, clearance products, stolen machines, etc. The warranty card is fake and there is no after-sales service. Once damaged, repair fees or scrapping are required, which is not worth it. Nowadays, not all the equipment sold in specialty stores may be expensive. There are many cost-effective equipment that can enjoy good after-sales service. Why not.
6. Equipment environment: Some small shops operate outdoors, and the staff's work clothes are very dirty. The sound system is installed, but the interior and exterior of the car are dirty. Buying a new car and replacing the sound system is a good thing, but it brings many negative consequences and is a heartbreaking thing.
A professional store operates indoors, and its benefits are:
(1) Clean, ensuring cleanliness both inside and outside the car.
(2) Not affected by temperature, it is easy to damage plastic parts when disassembling them when the temperature is too low. (3) Not affected by the weather, it can work normally when it's windy or rainy.
(4) Because of the lighting, it can work both day and night. (5) Customers have a good lounge.
