1, "professional power amplifier" is generally used for conference, performance, hall, hall, field, pavilion amplification. The design is based on large output power, perfect protection circuit and good heat dissipation. The timbre of most "professional amplifiers" is used for HI-FI playback, and the sound is hard and hard to listen to.
2, w audio should be equipped with 800-1200W power amplifier. Under normal circumstances, the power of the amplifier should be slightly greater than the power of the speaker. In the professional field, the power of the amplifier is generally required to be 2 of the power of the speaker- 2 times, preferably 5 times.
3, ** American Voice, Japanese voice, European Voice ** : These three classic combined amplifiers can push 99% of the shelf speakers on the market, is the dream of enthusiasts.
4. Software and media Sound source; Pre-signal control; Power amplifier mechanism; Loudspeaker; Transmission mechanism. Although the audio equipment is only an auxiliary equipment for the car, it has no effect on the running performance of the car.
5, the power amplifier of W is sufficient. My 150-watt amplifier usually only uses about 15 watts. Rarely use more than 20 watts, except occasionallyA little more power at "peak".
According to the official data of Wuling Hongguang S, the original sound system power of the car is 40W, if you use the original sound system, then the maximum sound should be 40W output. However, this does not mean that the maximum volume of the car stereo is 40 decibels or other specific values.
w. According to the query of relevant information, 18 Wuling Hongguang s radio original car radio power is low, you canDrive 25w power horn.
Wuling Hongguang s radio power is 40W. The radio capacity of Hongguang S is the same as that of many independent brand models, which is not too strong. In some empty parking lots, some mainstream radio stations are not very clear. If it is through a tunnel or a place with buildings, the radio capacity will be more discounted, and it is basically difficult to collect.
Wuling Hongguang S is one of the models launched by Shanghai GM Wuling Motors, which currently sells three models: 2018, 2019 and 2020. The vehicle's warranty is three years or 60,000 kilometers, and the maximum speed can be reached155 kilometers per hour, 50 liters of fuel.
Engine model of Wuling Hongguangs The first engine model, LSI, is a 2-liter naturally aspirated four-cylinder 76 HP engine with a maximum power of 56 kW and a maximum torque of 110 nm. The second, the engine model lar, is a 5-liter naturally aspirated, four-cylinder 99 HP engine with a maximum power of 73 kilowatts and a maximum torque of 140 nm.
The tank volume is 50L. The 2020 Wuling Hongguang s is equipped with a 2L naturally aspirated engine, the maximum horsepower is 76, the maximum power is 56 kilowatts, and its front suspension is developedp> Prepare simple tools, including file, sandpaper, hand drill, paper cutter, screwdriver, etc., you have a wiring diagram on the back of the sound, the car machine power is enough, the sound color is also good, the overall effect is good after modifying the home audio, more than the general computer active speaker.
I have used Kia car stereo to modify a home, I need to pay attention to things as a reference: first to get an output 12 volts, 5 amps power transformer.
If the output power of the car radio is 40w, the working voltage is 12v, then its maximum working current should beIt should be close to 4A. In this way, to 12V DC power supply, as long as the current is not less than 4A can meet the working conditions.
