1. Battery voltage.
The voltage of a car battery changes frequently. For the two commonly used signs: 14.4V/100W and 12V/100W power amplifiers are completely different power descriptions. Since the voltage of the car during driving is basically around 12V, the power value measured under the 12V voltage state is closer to the real situation. Moreover, a power amplifier with a continuous voltage of 12V as a reference to identify power can achieve greater power when it reaches above 12V.
2. Harmonic distortion rate THD.
When comparing the continuous output power of the power amplifier, it needs to be performed under the same (or relatively close) THD value. The difference in sound quality tested under different THD values is very obvious. Sometimes the maximum power of its logo is very high, but it is very likely that its distortion and noise are also very high. Therefore, while checking the maximum power, you should also pay attention to the THD value marked.
3. Frequency range.
The continuous power output of the power amplifier should be tested within its actual frequency range. For the power of the power amplifier, it should be required to identify the complete detection range, and only the power value at a certain frequency has no meaning. After determining the same benchmark, we can compare the power amplifier power. Generally speaking, the principle of high power output is generally followed when purchasing a sound system. The greater the output power of power amplifiers, the stronger their ability to drive speakers. The power of the power amplifier should be greater than the indicated power of the speaker. If the selected power is too small, it will easily burn out when using high-power output for a long time, and it will also cause problems such as poor sound quality and distortion.
