How to choose a car audio?

1. Refer to your own listening habits and style orientation, and refer to the characteristics of the speaker to choose the brand collocation, different manufacturers, not through the brand amplifier, the distortion may be very low, the sound dye is also very small, but there will still be some unique taste or style or timbre differences. For example, "Mingwei", "Lotus Flavor" and so on;

2 refer to the power impedance of the speaker unit to match, the impedance is consistent, the power amplifier is larger than the horn to meet the thrust needs of the large dynamic, the general power amplifier power is 1.5 times to 2 times the rated power of the horn, but also pay attention to whether the power amplifier parameters are false, some car power amplifier power is calculated with a larger voltage, such as the manual superscript 200wrms 4 ohms, etc., used in some cars, it can not reach the power of the standard, the voltage is about when the battery is powered by the multi-purpose car, and it is about after starting, Some power amplifier power will also be marked with 1 ohm load, such as 1 ohm 1000w, with 4 ohm speakers may only be about 250w power, false standard serious, will also be randomly marked with the maximum power of a few kw, etc., can be estimated from the fuse (if any) current nominal total value on the power amplifier. With a speaker with high sensitivity, it can be moderately relaxed;

3. Refer to the interface requirements to choose, for example, the CD player or the host is balanced signal output, you can choose the power amplifier with balanced input, for example, only unbalanced output, choose the power amplifier with RCA input, there is no audio output, you need to take the signal from the original speaker, you can consider choosing the power amplifier with high level input;

4. Refer to the power supply voltage to choose, the trolley is generally 12V, and the truck is 24V;

5. The reference channel needs to be selected, for example, if you push a 4-door speaker, you can choose a 4-channel power amplifier, you can choose a single-channel power amplifier for bass, and you can choose a bridge that supports bridge, active crossover or multi-line crossover, which can be selected according to actual needs;

6 Reference functions need to be selected, such as EQ needs, DSP functions, channel merging or conversion, such as 2 in and 4 out, etc.

7. Refer to the budget selection, if you have the conditions, consult the master with some suggestions, and consider the sensitivity, frequency response curve, transient response and other parameters if you can think of them temporarily.

The selection of car audio is mainly based on his sound quality. If you really don't know how to choose, you can choose the gll brand of car stereo, and his things are quite good.

Clause. 1. Mercedes-Benz S350, this car is the best soundproof and the best sound effect I have ever driven a car, because I am actually a audio enthusiast, I was fascinated by ** when I was studying, resulting in now becoming an auto mechanic, but CD records were more popular in that era, until I later participated in the work, I saved some money to buy the first car in my life, and the first car in my life is a domestic brand, the first thing I did after buying a car was to modify the audio, after some tossing, The sound didn't work well until I met a Mercedes. The reason why I like Mercedes-Benz so much, then it is mainly reflected in the driving experience, Mercedes-Benz's sound insulation effect is super good, and the driving feeling is particularly comfortable, especially when sitting in the car to listen to **, then Mercedes-Benz's audio is really professional, the same song, listen to it with the audio at home, and sit in the Mercedes-Benz car to listen, the feeling is completely different, if you listen to the music in the car, I can clearly feel that the human voice and ** have been better beautified.

Clause. Second, it is the navigator, this car is equipped with active noise reduction technology as standard, and it is also equipped with double-layer laminated soundproof glass as standard, and we can also see thick soundproof cotton in the engine compartment, and the door rubber of this car is very thick, and the sound insulation effect is the best in the joint venture car at the same price, at least so far, this car is the best I have ever seen. Usually if we drive this car in the city, the speed is about 60 kilometers per hour, it can be said that the tire noise and wind dryness can not be heard, and the ambient sound outside the car is also filtered well, which will make you feel isolated from the world, especially comfortable. If you are running at high speeds, you can still hear some tire noise and dry sounds, but if this car is compared with other cars in the same price range, such as the BMW 3 Series and Audi Q5, then the noise control of this car is really good.

Clause. Third, that is the Focus, then the main reason is that the Focus provides the hood sound insulation cotton, in addition to the engine compartment dust cover, and the center console is also designed to be very close to the driver, in fact, this design can not only compress the space inside the vehicle itself, then it can also effectively reduce the noise of the engine. It is worth mentioning that the doors and body of the Focus are designed to be very thick, so let's not discuss the deeper technical range, just analyze the entire frame of this car, it is conceivable that such a thick envelope will definitely be of great help to sound insulation. There is also a Focus equipped with a Sony host, the vehicle has a total of nine speakers, you can also adjust a variety of sound quality, especially the treble effect, it is really outstanding, so as long as you have driven this car friends, you should not have doubts about the Sony system, friends often say that Changan Automobile has poor workmanship, and also said that the Focus has many small problems, in fact, I personally think that every car has its problems, but ** in the level of ten to 150,000, then the sound insulation and sound effect of the Focus can be said to be, It's hard to find an opponent.

Clause. Fourth, it is Volvo S90, this car is a hybrid system. Then its sound insulation effect is much better than that of fuel vehicles.
