How can you upgrade your car stereo in the most economical way?

Buy a car ***** that is just popular now, it is a small thing that can be plugged into the mouth of the cigarette lighter, can adjust the FM FM FM, and then use the car's radio to receive, there is 1-2G storage space, can store more than 200 songs, which can save the cost of buying CDs, and can also avoid the heat problems caused by the car for a long time.

You can go to the 4S store, but pay attention to the following points when restructuringCar audio modification First of all, two things must be clarified.

1. Style What kind of voice do you like to listen to**, such as: vocal disco pop**, etc. Only a certain listening style can correctly choose the configuration and brand model of the audio system, etc.

2. Budget: There are many brands and models of car audio, and it is difficult to plan a plan if there is no approximate budget range.

Problems that need to be paid attention to in car audio modification.

1. Comparison No matter how well the reviews or recommended articles on the Internet are written, they can never explain the real effect of the sound, and only hearing it with your own ears is the most true and objective, so you must listen more, walk more, and communicate more.

2. Reasonable configuration of sound source (host or signal processor), power amplifier, speaker, wire This is several components of car audio The equipment of each part should be in a balanced state Only in this way can we match a set of audio systems with ideal effects.

3. Professional installation and commissioning The so-called three-point equipment and seven-point installation must find a professional audio modification shop to install It is not that DIY is not advocated, but there will be a lot of discipline knowledge involved in audio modification Automobile electrical, carpentry, hand-pasted FRP, etc. Most of these majors are not available to ordinary car owners.

Method 1: 1, the host is best to use CD, MD or ***, if it is only used to listen, or choose CD and MD, VCD poor sound quality is best not used, *** belongs to the compression format, although the current *** audio has increased the sound quality processing circuit, but it is still not as good as the sound quality of CD. The main machine chooses a model that does not have any modification to the signal, that is, the "original" of the so-called Yutan.

2. Because the modified signal is not the original waveform, it has been distorted, so it is not ideal. If you use the host to push the speaker directly, you should choose the high output power, and now the output power of the host is generally 4 50W. If you use the pre-output of the host, you should choose a high output level, the purpose is to improve the signal-to-noise ratio, and the output level is generally 2-4V.

By the way, CD records should be selected**, and it is best to use "DDD" printed on the disk, which has good sound quality.

3. Don't insist on pursuing too much work without dismantling and dressing up, as long as the function of the equipment is moderate and the basic requirements are satisfied, but don't try to be cheap and miss the basic functions you need. The input and output ports of the equipment should be considered in advance, which are necessary and which are dispensable, so as to avoid inconvenience in future upgrades.

Method 2: 1. When choosing a speaker, you should first consider what kind of audio system to use. According to the system - sound quality type such as: classical, symphony, light **, etc., the sound quality should be clear and soft.

2. Sound pressure type (i.e., "fryer") such as: disco, rock, etc., should choose a speaker with a firm structure and large dynamic range. According to the power - it can be divided into, if the host directly pushes the speaker, you should choose the speaker that matches the output power of the host, and generally choose the speaker with high sensitivity, which is easy to push and play a role.

3. If you choose a speaker driven by a power amplifier, you should use a high-power speaker, which has a large dynamic range, confidence and full sound. According to the type, it can be divided into - coaxial, split, multi-channel, subwoofer, etc. At the front, the most used is the split type, because the split type separates the treble and mid-bass, which is easy to install and localize the sound field, and some have treble attenuation in the crossover, which is easy to adjust the treble intensity.

Method 3: Match the amplifier with the speaker.

The matching of power amplifier and speaker mainly refers to impedance matching, power matching, sensitivity adaptation and timbre matching. Car Audio:

1. The most basic condition of car audio is that it has the function of playing back sound. In order to qualify as a sound system, it must contain at least the following points mentioned in order to be called audio, which is the case with any audio system, and car audio is no exception.

2. According to the data of "China Car Audio Industry Market Prospect and Investment ** Analysis Report Prospect" data as of the end of 2010, China's car audio market size is close to 3 billion. However, in China's car audio market, Japanese brands account for 50% of the share, European and American brands account for 40%, and Chinese local brands only account for 10%.

Hello, dear, I'm glad to answer for you in Chunqi: you can install a subwoofer, **1000 or so, if you are blind, there are a lot of good sound quality after installation, and there is a kind of speaker system for the whole car to be replaced, which is more expensive and estimated to be more than 1w, there is no need to add a subwoofer is enough.

First of all, it is recommended to install a more entry-level horn, suitable for the original car without a horn or the horn is damaged modification scheme, compared with no horn is still a great improvement, but can not be compared with professional-level products. If you can't achieve the effect you want, you can install a lot of equipment, such as replacing the professional car horn, replacing the audio source host of the scattered industry, installing subwoofer and so on.
