Go to the store to change the stereo.

I believe that everyone, like editors, usually has their own shop to visit when repairing cars and washing cars. However, it is also an important measure to help you choose a set of audio that suits you and meets your needs, in addition to the good technology of the refitting shop, which requires the boss to have certain professional literacy ability.

So, how to choose a suitable point when modifying the car stereo?

For ordinary car owners who only need to repair cars, it may only be necessary for the store to have a business license. However, for those who need to modify their stereos and pursue a higher quality of life, they can choose some shops with honorary certificates.

At present, there are probably several large car audio competition organizations in China, such as IASCA, MACE or MACA. Generally speaking, if a store has these certificates or will be awarded, it will not be too bad. Of course, there are also shops that take these just for gimmicks. I believe everyone understands the hidden relationship behind them. But relatively speaking, the owners of this award-winning shop have certain professional knowledge and are trustworthy.

An ordinary refitter will only help you install it. What kind of stereo you want to buy is up to you. If you are a novice, Xiao Bai, it is estimated that you will have a lot of trouble. So when you enter the store, you can simply ask the boss what discs he usually listens to, infer his level, or tell your needs and see what solutions he has to meet your desired sound experience.

If you are not sure about raising the flag and are a little white, you can buy an introductory set. Recently, the editor accidentally discovered a brand of "Leidao Audio", which has a high cost performance and has a good performance in all ranges.

Now it's basically USB or lossless wireless transmission, so you don't need to bring a disc.

Many people don't pay attention to the acceptance link, thinking that "it can be used, almost" is enough, but it is not, and the water inside is deep.

Many unscrupulous shops will use all kinds of tricks to force you to continue to spend money to upgrade, instead of playing the role of the equipment you bought. A simple example is to switch the anode and cathode of the speaker. Although it won't burn your horn, you can still sing, but it will offset the low frequency, and the whole voice will become dull and float. At this time, the store will suggest that you install a subwoofer, but you don't need to install it.

So how can we avoid this situation? At this time, a small device "phase tester" can be used. You can see if there is one in the shop. If not, you can buy one online for about 30 yuan. When the tester is put in for testing, it will produce three or two sine waves, and then if it is installed correctly, the machine will generally display three green lights and one red light, or two green lights and one red light. Doing so can prevent the store from installing the wrong speaker for you as much as possible.

Finally, we can look at the installation process, the arrangement of wiring, the fixation of treble, whether the speaker is locked and so on. After these things are done, there will generally be no major problems.
