Obviously, the car audio is power-intensive, and the sound is driven by solar energy without electricity. Having said that, let's talk about how much electricity a car stereo can cost.
How much power is a car stereo
The power of the stereo is exactly RMS power, first of all, how much power your car stereo is varies from car to car. The better the sound quality of the car audio, the greater the power, such as Volvo Bauer Vegen, which is known as the hall of the automotive industry, the maximum power can reach 1100W or 1400W. The power of the most common family car 4-speaker speaker is about 150W, the power of the 6-speaker speaker is about 200W, and the BOSE audio power equipped with about 200,000 models is about 400W.
So the cost of car audio depends on your model first. But what is listed here is the maximum power, and the daily listening to songs cannot reach such a high power. The RMS power of the speaker is like the maximum horsepower of a car, and it is generally impossible to use the maximum horsepower when you drive.
How long can I listen to the car stereo after the ignition is turned off?
Under normal circumstances, the battery capacity of ordinary family cars is about 50-60AH, the output voltage is 12V, if it is 60AH, the capacity of the battery is 12V * 60AH = 1200WH, but this is the full capacity of the new battery, plus the loss situation, if the power is full, Volvo equipped with Baohua Weijian audio can play about 1 hour of music, and ordinary family cars can play about 4-5 hours of music. But again, this is the case of the new battery full power, the actual use of the process basically can not hear such a long time. One is because the battery is generally impossible to be in a full-power situation; the other is because the battery capacity will gradually shrink after a period of use of the new battery.
Does the flameout concert damage the battery?
In fact, don't worry about this problem, there is no problem at all to turn off the ignition and listen to music for a short time, because the current car basically has a low voltage protection function, unless you have a low hand in the low voltage protection after the low voltage protection is turned on, frequently restart the audio, otherwise the car can be ignited normally.
If your car is an old model, there is no such function, then do not turn off the ignition for a long time to listen to music, if the battery is exhausted and can not play the fire is troublesome, take the mobile phone to listen to the song is not also very good.
