If the car audio fails, you should go to a special car audio repair station
Car audio is different from home audio. The circuit design is also more complicated than home audio. Non-professional repair stations do not even know how to disassemble. Without test equipment and special equipment and tools, it is difficult to restore the audio to the original standard.
The maintenance of car audio not only needs to check the failure of the audio itself, but also comprehensively check the wiring of the vehicle itself to eliminate the impact of the vehicle on the audio. Most car stereos use highly integrated chips and circuit boards, including multiple functions in a small volume. Repair personnel need to have certain car audio technical knowledge and maintenance experience. The establishment of a car audio repair station is not a simple matter. The initial investment in equipment, maintenance materials, spare parts, personnel training, and experience accumulation is also huge. Only after authorized by the manufacturer can we further obtain the technical information and original factory of each car audio. Only accessories can guarantee the maintenance quality.
The spare tire has been left in the car for many years. Does the spare tire have time to use it?
Spare tires are generally used for 4 years. Many car owners believe that as long as they keep the spare tire in the trunk and do not use it, they can "live for a long time." This is wrong. It often happens that the owner wants to replace the spare tire after the tire is punctured, but finds that the spare tire has been seriously aging after being placed for many years, and is already a waste tire. In fact, because tires are rubber products, the aging phenomenon will occur when stored for too long. Generally, the aging period of tires is about 4 years. Therefore, the spare tire should be replaced after 4 years.
The main component of the tire is rubber, and the rubber is most afraid of the erosion of various oils. Therefore, if the owner often stores oils such as lubricating oil in the trunk, once these oils get into the tire, the tire will swell and erode Greatly reduce the service life of tires. If the tire gets oil, please use a neutral detergent to wash off the oil.
What are the main types of automotive glass
Common automotive glass has the following types: tempered glass, partially tempered glass, laminated glass.
Tempered glass has internal stress inside. This internal stress makes the glass have a high resistance to physical impact. This resistance is 4 times higher than ordinary glass. When it is subjected to a strong impact, it will break into particles and will not Cause personal injury; local tempered glass is a type of tempered glass, as strong as tempered glass. Originally developed to make windshields for cars, when it breaks, it will form fragments of special shape and size, which can provide some visibility and additional safety for the driver; laminated glass is made of two ordinary pieces of glass glued in between There is a layer of film, which is pressed by super glue.
The film sandwiched in the middle when broken can prevent stones or other flying objects from penetrating to the other side, and can also prevent broken glass from splashing. Laminated glass can guarantee the minimum visibility required for driving.
In addition to the above three types of glass, automobile glass with other special functions also includes: hot-line mark glass, stained glass, etc. Their common feature is that the transparency has reached 70%.
