What is the no-load current of a 4-channel 12V car amplifier in amperes?
1 Answers
Generally, a car amplifier has a no-load current of only 1 to 2 amperes, which is about 10 to 20 watts. Below are the specific details: 1. Car amplifier parameters: This parameter should be discussed together with the other two important parameters of the amplifier: "rated power" and "maximum power." When the amplifier operates below the rated power, the distortion should be very small, typically within the range of 0.5% to 0.01%. 2. Key indicators: When reaching the maximum power or in bridge mode, the signal may experience distortion, such as clipping (incomplete waveform signals), and the distortion ratio may increase accordingly, with values around 0.5% to 1% being normal. The smaller the distortion ratio, the more ideal the sound effect, which is also an important indicator of the amplifier's performance.
