1. Generally speaking, the power of the power amplifier is higher than the total power of the speaker system, so as to ensure that the sound will not be distorted and better cope with signals with large peaks and large dynamics. Generally speaking, the power is 1.2-2 times that of the speaker system, but the sound pressure should be controlled to prevent box burning.
The peak power of a speaker is generally four times the rated power of the speaker, depending on whether 300W is the rated power of the speaker or the peak power of the speaker.
2. For four 300w stereos, that is, 1200w, you can choose a power amplifier around1440 W. ..
Extended data:
At present, there are many ways to label various powers, such as rated power, root mean square power, peak power, maximum music power and so on. The power mentioned below refers to the rated power.
1, in general, the power of the amplifier should be slightly greater than the power of the speaker;
2. In the professional field, it is generally required that the power of the power amplifier is 1.2-2 times and 1.5 times of the sound box;
3. In the field of home Hi-Fi, the power of the power amplifier can be twice that of the speaker;
4. Another thing to pay attention to is the sensitivity of the speaker. The higher the sensitivity of the speaker, the less amplifier power is needed to drive it.
