With the increase of private launch x431 gx3 cars, people drive time increases, the car more and more like a modern a mobile home. A boosting or soothing music can change the occupants feelings, while the bad sound effects will only make the mood worse. Who can bring us the mood? The answer is car audio.
The original car audio system are disappointing. Because the car is a car, not a multimedia computer or household appliances, love audio friends only through modification to meet his high standards of hearing.
Want to modify the car audio drivers, the most important step is to choose a good sound. This article will introduce how to choose a good car audio. Select car stereo before must learn to judge car audio quality!
How to judge the car audio quality?
Car audio is the main component of the host, power amplifier and loudspeaker. Car audio host is the most direct is to see its technical indicators, mainly has the following several aspects:
1, output power: for the vast launch x431 gx3 majority of music power, in the 40W ~ 60W, power of the bigger the better.
2, the frequency response : the human ear can hear frequencies in the range of 20HZ～ 20KHZ, therefore the indicator must be at least the number, and more and more wide.
3, signal to noise ratio: a music signal and noise ratio, high-end car audio more than 90DB, the bigger the better value.
In 4, total harmonic distortion ( THD ): embodiment of sound reproduction fidelity, numerical value is that the reduction degree is higher, the better it is.
Buy car audio specific steps
In 1, according to their grade and economic capacity and
Clearly this expense is specifically the amount of fees, because good sound natural to have good price. In the high-end luxury cars generally have a more advanced professional audio, with Europe and the United States products better, its tone quality, the product a more professional than japan. But at present, some famous Japanese car audio brand also has introduced some have a fever with Europe and the United States to counter the brand. Although the performance is good, but the price is really amazing, is absolutely good, the indicators can achieve famous brand listed on numerical and long-term continuous use. Such as the selection of high-end audio equipment is launch x431 gx3 a product of Japan itself, its brand in the professional car audio equipment accounted for 2/3. The price and performance ratio value for money, and from a functional completeness and appearance modeling, decoration and sophisticated technology and other aspects, it is Europe and the United States products cannot compete with.
2, to consider the host power capacity
Power amplifier is the sound system of the heart. Power amplifier power size, quality of the music player plays a crucial role in.
How to select the power amplifier? First amplifier power and horn power match; secondly should choose to have built-in divider of the amplifier, so that the system can be free of power amplifier and loudspeaker combination, but also makes the whole system can improve the sound quality. When the choose and buy should also pay attention to try to choose large enough to maintain normal radiator, heat sink.
3, to understand the speaker 's performance
In the high-end host performance difference is not too large, the difference is staggering trumpet. A speaker could mark the last few hundred watts of power, make many pedestrians also confused, not the nominal lexia 3 pp2000 power is greater, the horn and the real power is big, to make the perfect music, is the need of power amplifier and speaker perfect matching to achieve. In sound without distortion condition, horn vibration frequency is very high, it has a very high sensitivity, the sound performance ability is very strong, and will not burn. And for which the sizes of the magnets, can give people the visual impact, do not think that the larger the magnet power more.
In 4, grade decided the type of music
From the type of music on the car stereo is divided into three categories. First class ( acoustic type) is to listen to classical music, symphony, light music, pure sound fidelity requirements of high reduction effect is good; second ( energizer type) is fried models, is listening to disco, rock, only the pursuit of great volume, to the quality requirements are not very high; third ( Theater type ) DVD and Dolby 5.1 channel theater system, TV, DVD, VCD, MP3, CD, radio and other functions, is the main entertainment.
Three types according to their needs to decide the modified sound level and equipment, to achieve the desired effect, this is what we need.
