Working voltage: DC 12V-35V (corresponding to 9-26V transformer, power needs to be greater than 100W)
Output sound power: 10-15W
Size: 100*78*36MM. Angle aluminum 2 fixed hole distance 53MM The default is 24V, 1.2A, which can be used for current flow.

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.
