Remember the previous interview, let the store manager recommend me some relatively good products, they will reveal a very hard look. Because I did not tell them my musical preferences, and did not say my budget, so it is not possible to recommend the product. So in this issue, I will tell you some practical skills of converted audio.

Because most owners for car audio is also not very well, so that converted audio is a very complex thing, but if you follow these few steps, this process is very simple.

1. in alterations, "self-centered"

I really like the term "advertising" Science and technology people-oriented ". In the converted audio, we also have to the spirit of "self-centered" this principle.

(1) why did the converted audio conversion. If you can't figure out why conversion audio, then be sure to clearly say. To not spend a lot of money to refit the sound, but no feeling, is it not worth the money spent.

(2) the preferences of their own music. In mind the purpose of the modifications and alterations in the future, it is necessary to clear your music preferences, that is, what type of music to listen to. Because different brands of car audio, apply different types of music.

(3) more understanding, reduce scope. Now on the market, many car audio brand, in so many products in very difficult indeed. Therefore, it is best to just look at the car audio market, more information, or to the expert consultation. Of course, before the consultation, to determine the budget as well as their preferred music type, and experts to give their views.

2. in alterations, a full understanding of the objective situation

In the converted audio before we want to understand their needs, and grasp the subjective thoughts and, when you will have to be converted, see objective situation.

(1) "price" ratio. In consultation with experts, to select the scope to a few products, you can begin to compare various car audio shop price. According to my experience of this period of time, the different shop prices vary a lot. Of course, must be converted to the regular stereo shop, quality is difficult to guarantee.

(2) of the audition. Each brand has its own different features, so be sure to select several products to audition. This time all about product performance are redundant, only believe my ears is the absolute principle.

(3) setup fee. Some audio shop installation costs are not included in the purchase price within the host, this part of the purchase must communicate clear and shops.

(4) to supervise the installation. This is mainly to prevent the installation of shoddy work.

(5) acceptance. After the installation is complete on the spot inspection course, listen to is not your favorite effects.

3. refit, the aftermath

Don't think that ends the conversion is complete, you have to deal with the aftermath.

(1) check. Conversion finished, be sure to follow the instructions on the presentation, check the remote control and bond, and other things are complete.

(2) for invoices. Fill out a warranty card and ask for an invoice, the sound and secure problems occur.
