Car audio capacitors are auxiliary components for high-end car audio CD players, MD players, DVD players and high-end power amplifiers to improve the quality of audio reproduction. Filter out a variety of noise in the power supply. Because the capacitor has the characteristic that the voltage at both ends of the electrode cannot be changed suddenly, the noise wave in the power supply is absorbed by the capacitor, so that it is contained before the power circuit enters the mainframe and amplifier circuit of the car audio. The audio signal 'flowing' in the main unit of the car audio and the power amplifier is an AC signal within a certain frequency range. The AC signal can pass and be amplified only when it forms a loop. To form a bias voltage in a transistor circuit, a resistor must be used to form an amplifying circuit. The use of the electric group device is a necessary condition for forming an amplifying circuit, but there is also a negative effect that affects the AC signal path, that is, to a certain extent, affect the passage of audio signals. The function of the capacitor is to make the AC path of the circuit more smooth without changing the DC parameters of the circuit, which also enables the very weak signal in the audio signal to be amplified, and the signal loss is smaller, and the sound quality is also reduced. It's even higher. The energy storage function of the capacitor also takes advantage of the characteristic that the voltage across the capacitor cannot produce abrupt changes. When the power amplifier outputs high-power energy, due to its energy storage function, its rapid response dynamic characteristics can quickly replenish energy to the power amplifier circuit, reduce the power supply voltage drop between them, and create the necessary working conditions for the normal operation of the power amplifier. 1. It can reduce the noise caused by poor power supply of the machine head and power amplifier. 2. When playing a large dynamic program source, reduce the non-linear distortion of the amplifier caused by the sudden voltage drop. 3. In a good car audio system (the effect is not obvious for a low-end car audio system), because the signal loss in the circuit is smaller, the mid-range part can be full; the high-range part has sound permeability Better, the sound is brighter; make the bass part more substantial and flexible. It plays an irreplaceable role in improving the sound quality of car audio. Automobile capacitors are called 'big ponds' in the south. As the name suggests, their role is to have sufficient water supply in the 'big ponds' to ensure that the machines work better. 1. According to the brand of the capacitor, choose a capacitor with a smaller internal effective resistance, a famous brand audio capacitor will make the effect better. The working voltage should be above 25 volts, and the working temperature should not be lower than 85°C  . 2. The choice of capacity is based on the power of the power amplifier. The capacity of the main unit is generally selected from a thousand to 10,000 microfarads. The capacity selection range of the power amplifier is generally 50,000 microfarads, 100,000 microfarads, 500,000 microfarads, 1 farad and 1.5 farads. For higher-power car audio systems, multiple capacitors are generally selected in parallel. 3. In the choice of use of the capacitor, a small farad number and a large farad number can be used to make the equivalent internal resistance smaller. 1. A fuse should be connected in series with each capacitor to ensure circuit failure caused by capacitor failure. 2. The installation position of the capacitor should be as close as possible to the car audio machine or power amplifier, and the short and thick power cord must be used for connection. The end of the power cord should be tinned. In addition, it should be pointed out that the car audio capacitor is only an auxiliary equipment for car audio. It is impossible for all car audios to have a very large sound quality change, but its finishing touch in high-end car audio not only uses the basic circuit The theory can be explained. If installed properly, the sound of your high-end car stereo can be said to be three-pointers.
