Myth 1: The number of speakers is as good as possible! From the working principle of the speaker to explain: the frequency range that the human ear can hear is 20Hz ~ 20000Hz, a speaker can not take into account the spread of the full frequency range, the different sizes of the speaker division of labor cooperation, like "men and women, work is not tired", around Stereo can be formed by two channels. Each channel has 3 speakers in high, medium and low. It is not enough for the speakers. The high and medium bass is complete... Good! Acoustic explanation: The sound is actually a "sound wave", and the sound waves emitted by the various speakers will interfere with each other. Some frequencies will increase and some will cancel. The more the number of speakers, the more serious the sound waves interfere with each other. The more speakers, the higher the requirements for tuning, so the more speakers are not the better, there are professional tuning technology and equipment... good! Myth 2: Excessive pursuit of surround sound! About surround, stereo and hi-fi... High-fidelity music is not surrounded by movies. The biggest purpose of car audio conversion is to restore the stage above the instrument panel, in front of the listener. Stereo can restore the sound field positioning of the original sound. The wider the frequency of the speaker, the better the sound. The more details the speaker presents, the better the sound. The sound of the speaker is more beautiful. So not the more speakers, the better, the performance of the speakers is far more important than the number. The original car audio of the car...the number is not a lot... The biggest reason is that the quality of this speaker is not high, so it is necessary to have so many speakers. Because the quality is not high, the energy emitted by each speaker is relatively poor, and the density is weak, so it is necessary to use so many speakers. And so many speakers... It's very noisy to do stereo, because each speaker is superimposed too often. Too much stacking sounds noisy, so... you have to make it a surround sound. Surround sound... The frequency of the speakers is different for each front, rear, left and right. The division of labor is relatively clear. If the number of speakers is large, it will not be so noisy... The original factory still has the original purpose. Because the number of original horns is generally more, many car owners want to change the sound. When they come up, they say they have to install 16 or 18 speakers. This view is actually wrong. Because we modify the brand's speakers, the quality is relatively high, so we don't need so many quantities, the effect can be better than the original ones... Myth 3: Transplant the original big-name speakers! Now there are a lot of people on the Internet who want to buy the horns of the car parts... Someone came up and asked: "Do you have Harman Kardon?" I asked him what car? He said: "I am the public!" Then I said: "Is there a horn that has been installed by Harman Kardon? No..." They will think that as long as it is Harman Kardon, all cars can be loaded. In fact, the original car audio is the corresponding model. Because the shelf of the original horn is dedicated to the car, and the horn is integrally formed, the horns of many models are not interchangeable, because the shape and size of the horn are different. The original car horn is integrally formed with the bracket. The original car horn brand is different and the shape is different. There are a lot of cottage BOSE, Harman Kardon, B&O on the Internet... In fact, these are fake, just like the modified speakers, followed by a big-name logo. The seller tells you what car can be loaded, equivalent to the universal model, standard speaker. In fact, the original car's brand audio is not a so-called "standard speaker." At this point, many people have been deceived... PS: Standard horns are usually found in modified branded products, and can be installed in different models by replacing shelves of different shapes. Modification of the brand's standard speakers and corresponding brackets for various models. Generalization is achieved by different brackets. Modified brand standard horn bracket, dedicated to the car. Take the example of Harman Kardon, Harman Kardon on the BMW car... You think the effect is not bad! In fact, this is inseparable from the power amplifier and host corresponding to the model. Then you buy a pair of high-profile models with trebles to add, can the effect be good? Definitely not good. After many people did this, they asked me why the effect did not differ... Take BMW as an example. The low-end models are all "commercial-grade audio", which is "Business Radio". Today (in recent years) most of these BMWs have no tweeters in their original cars, but their midranges. It is called "medium and high-pitched sound". If it is a high-fidelity sound, with a power amplifier, the middle of the head is the real "middle". Then there is a high pitch and a bass. Therefore, the original set of Harman Kardon's whole set of things, you have to buy all, the lack of the same can not achieve the original effect, this is the original factory tuning. You are not the model of this configuration, even if you buy a Harman Kardon speaker, you can't achieve that effect. Why can't I transplant a speaker directly? Because many of the original horns are defective, the original car's amps have been tuned, which is a certain compensation for the horn, try to put its advantages out. If you only use that speaker, then you will use its shortcomings... Solid-state capacitors / Motor starting capacitors
Solid - state capacitors are all called: solid - state Aluminum Electrolytic Capacitors.It with the ordinary capacitance (that is, the liquid aluminum electrolytic capacitors) the biggest difference is that use different dielectric material, liquid aluminum capacitor dielectric material as the electrolyte, and solid-state capacitor dielectric material is conductive polymer materials.Solid-state Capacitors / Motor Starting Capacitors
