How to choose a power supply?</b></br> ?The power supply must be highly valued. It is recommended to use 18V 19V 24V power supply with a current of more than 5A.</br> ?If the voltage is too low, the sound will be easily distorted after the sound is amplified; if the current is too small, it will not work normally or the sound quality of the speaker will deteriorate.</br> ?If you only have 9V 12V or 1A 2A power supply, you can also use it, but it is recommended to use it with a speaker with low power. Otherwise, if the volume is maximized, it may be distorted and affect the sound quality.</br> </br> <b>2 How to choose a speaker?</b></br> ?Commonly used speakers are generally 8?, 4? speakers are also available, no distinction between positive and negative polarity.</br> ?If the power of your speaker is low, it may be between 10W-30W, then the power supply voltage should be lower to prevent the speaker from being burned after amplifying the sound, for example, choose a power supply below 15V.</br> ?If it is a 50W-300W speaker, you don’t have to worry about the speaker burning out. You can choose a 12V-24V power supply. The higher the voltage you choose, the greater the output sound or power.</br> </br> <b>Package Includes:</b></br> 1.
