Questions and answers:

1. How to choose a power supply?
The power supply is critical. The higher the voltage, the higher the current and the better the output power. We recommend a minimum of 9v. If you only have 5V 1A, you can use a 3-4 inch speaker. If you are 19V 5A or above, there is no problem with larger 8-10 inches but please make sure the power supply is high amp rated. If the voltage is too low, the sound will be distorted after the sound is amplified. If the current is too small, the speaker will pull the voltage low, work poorly and the sound quality will deteriorate.
It is recommended to use 18V-24V power supply with current above 3A. If you only have 9V-12V or 1A/2A power supply, it can also be used but the power is smaller. Please pay attention to the maximum volume when using it, which may affect the sound quality.

2. How to choose speakers?
Commonly used speakers are generally 8 ohms, 4ohm speakers can also be used.
