Now readers are increasingly demanding audio knowledge, and I think it is time to write an upgrade article for car audio enthusiasts. Car audio has progressed very fast in the last decade, but the fundamental concept will not change. I hope everyone can get some inspiration and some feelings.
For a long time, the car audio conversion industry style is very conservative, and because consumers themselves do not know enough about the sound, the consumers who are slaughtered by the audio store and still complacent are too numerous to list. The level of the store is uneven. Most of them are never listening to live concerts. They don’t learn musical instruments and they don’t have audio-visual apprentices. They do have a good level of installation and carpentry. But there is a lack of systematic adjustment in tuning. Training process. An old predecessor said that half of the money spent on car audio is wasted, but the problem is often not knowing where to waste.
I personally feel that to improve the level of domestic car audio conversion, only from the level of improving consumers, when consumers know enough, they have the ability to ask the store. In the United States, most of the consumption patterns are that the store is in the installer's position. Most consumers can plan for their own systems, and then consult the store about the feasibility of the system and the choice of equipment. On the other hand, the domestic environment is very bad, and most of them are tied to the store by the general agent. Therefore, when you go to a store, you will only tell you that a brand is the best in the world, and other brands are abandoning it. It is because of this abnormal market structure that the information that consumers can get is very unreasonable.
Now readers are increasingly demanding knowledge, and the author believes that it is time to write a series of upgrade columns for car audio enthusiasts. Car audio has improved very fast in the last 10 years, but the basic concept will not change. I hope everyone can get some inspiration and some feelings.
Database: store selection
Choosing a store is an important part of the audio upgrade. A good store can not only satisfy you with the upgraded sound system, but also does not cost too much money.
You are the designer of the system; the store is the installer
You must first understand the type of music you like, what are the requirements for the system you make, how the tone is, how it is positioned, the requirements for low frequencies, and the level of integrity required for the luggage compartment and the interior of the car. Telling the store about the requirements, in addition to the installation and adjustment of the store, the system design at the beginning is actually the most important. He can tell you what equipment will suit you, how much budget you need to meet the requirements, if the budget is not allowed, then arrange the upgrade plan step by step, which will let you feel the improvement to keep you motivated to upgrade; Can maintain the flexibility of the upgrade.
When choosing a store, don't go to a store with too strong a single brand. In the habit of most stores today, if you go to a special store of a certain equipment, you will tell them that their equipment is a good product, and the rest are bad. However, it is only based on commercial interests and bullying consumers do not understand the equipment. Equipment may be really good or bad, but to a certain level or above is a problem that you like or dislike, not just quality.
Store location
If you just want to modify the host and the speaker to stop the reader, the store may be a good place, because these equipment does not need much adjustment, where the price is more open, the store is loaded with a lot of familiarity with the equipment, Therefore, the chance of error is not great, and the disassembly and assembly of the interior is fast and good.
As for some of the often-acclaimed stores, they may be inclined to install a large system, but don't be shocked by the store's award-winning momentum. You can ask to listen to the actual car. If the store knows that you are an insider and will let you audition, it means that he is very confident. If you are installing your own equipment, it should not be a problem to talk about the price. But at this time, the level of familiarity with the equipment is very important. If you are unfamiliar with the equipment, you will not be able to talk about the school.
Store familiarity with equipment specifications
Many stores do not give consumers a guarantee and a manual after loading the equipment. The frequency response of the individual inquiry is not known. It is true that the specifications cannot be completed by the specifications alone, but the data and the calibration of the equipment are Ready to be so memorable, the so-called professional level can be imagined. Sometimes consumers buy subwoofers and speakers, the store is said to be the original US factory, but without any guarantee, after the consumer found that the speaker is domestic, the inside of the box is shoddy, the store said that it is the general agent, to consume The owner went to the general agent himself. The consumer thought that he would like to redo the speaker himself. He asked the store for the single parameter. As a result, as long as he came to a model data sheet, the store re-applied the skill and said that he had tried his best. He has tried his best. Also deceived by the general agent. I don't know how many such stores are in China, and the owner is also proud of his professionalism. It is also a ridiculous car audio legend.
Advise all the riders to take the manual and the guarantee when they spend money, otherwise they will have to explore for a long time in the future.
Measure the strength of the store, N small problems
If you have a certain involvement in car audio or home audio, you can measure the strength of the store.

a. How does he estimate the current and fuse number required by the system?
