Japanese brand into a main

At present, Chengdu, car audio installation can be a place mainly car decoration shop in the main, concentrated in the vicinity of Xiaojiahe and Hongpailou. There are hundreds of audio brand as much, but the more popular or that a handful of imported brands. In addition to traditional host-choice type of CD, there are now well VCD, DVD, MP3, MD and other popular new products.

From the above we can see the origin of the brand, currently in Chengdu, car audio products are basically Japanese-based fight. Despite the low price of domestic host (only half of Japanese products), but why the market is hard to find? Or a business which tells the whole story: \"Now we are afraid to sell the domestic host, the host made last year, we bought some, is almost sold out once a problem, customers keep coming back for repair, installation business we thought it was on the issue. \"

To understand the brand identity

Each audio brands have their own merits, and thus the choice of sound of the brand, understand its essential quality characteristics. Chengdu on the current market the brand, sound engineer to do Comments: Alpine car audio for a professional, it is the most popular brand of the highest market share.

On this basis, also with amplifier, equalizer, crossover, choose a separate high, medium, subwoofer, and a separate subwoofer. But first thing to consider is the host. Host of music software such as magnetic or digital signals into a corresponding electrical signal. The second is the speaker, also known as speaker. Reflect the personal taste of the speaker is electro-acoustic conversion devices, different speakers have different voices, the sound performance is divided into European style, American style and Japanese style. Car audio speakers are usually divided into component speaker (split horn), coaxial speakers and subwoofer. Coaxial speakers generally lower cost, but also easy to drive, but the sound field localization and sound are not as perfect as speaker package, so a good set speaker sound system is recommended. Set the range single speaker is separated from the design, then set the crossover frequency of the speaker as a combination of sound quality of this design is better, are more likely to get a good sound field positioning effect.

Speaker selected, the amplifier has carefully selected. Select the first consideration is the amplifier current amplification of the true extent of the sound (that is, fidelity), and speaker matching heat and power, and product stability. Amplifier with high technical content, it is proposed that imports of selected professional products.

Avoid blindly install stereo

During installation of the sound, because of the consumers themselves do not understand the line, often appear out of the result is not satisfactory installation, or installation of process waste money.

First, businesses can choose to see whether there is sound brand licensing the construction certification, and should choose a more well-known large-scale formal businesses. Second, we should pay attention to the construction process. Before the construction deal with their own brand of audio for the selected audition, so that construction be completed before we can have a comparison. In fact, many of the sound is not good in fact, not compliance with the construction of a relationship, the problem often lies in the installation and debugging.

car audio conversion project: the installation of a subwoofer.

Problem:

1 subwoofer directly connected to the common power supply circuit.

2, the bass line of control and power cathode connected together, when the key is unplugged, the subwoofer lights were still bright.

Hazard:

1, ordinary car stereo\\ s power cord is generally unable to meet the needs of car subwoofer, this link is easy to cause a short circuit, the light will accelerate the aging of the circuit, leaving for future long-term use of circuit problems.

2, low long-term cause and effect of electric gun is no problem in theory, but any electrical appliances are likely to random failure, once a serious problem affecting the power supply circuit, the car unattended, the problem can be thought of
With knowledge.

The right connection: exclusive use of car audio power cable, power lead from the battery. Within 30 cm away from the battery check access a waterproof fuse box. Power cable through the firewall should be reinforced insulation. In order to prevent aging of the power cord, power cord should be put on the whole line flame retardant snakeskin casing. Solder joints should be rinse process, associated with the battery or the power amplifier should be used when lines the nose.
