The power supply voltage is higher relative to the power will be larger, different impedance speakers will have different output power. In the case of sufficient voltage and current, the larger the speaker ohm, the smaller the relative sound power, please pay attention! _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Note: _x005f_x000D_ Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! _x005f_x000D_ Please allow 1-2cm measuring deviation due to manual measurement. _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Included: _x005f_x000D_ 1Pc *Power Amplifier Board
