The default is 24V, 1.2A, which can be used for current flow. The higher the current is, the more heat is recommended.
      choose a 3-5 inch full-range speaker, and you can choose a full-range speaker with a 5-8 inch diameter. You can also choose a speaker with a power below 120 watts and below 8 inches.
Adjust the current:
The universal meter hits the current 10-20A, the VCC line is not connected, the red meter pen is connected to the VCC terminal of the rectifier board, and the VCC terminal of the black test lead connected to the power amplifier board is the measuring current. Adjust the KT2 on the board (W202 at the top of the part) to change the current. 1.2A is recommended.
Note: The hole for measuring the midpoint/current red pen is different. When measuring the current and then measuring the midpoint, you must change the red pen hole.
