Product details:

1.This is a DC-powered 12-24V power supply, using TI's TPA3116D2 high-performance digital power amplifier as the core, one to do parallel bridged ba channel power amplification output, one to do left and right channel power amplification output.support 100W (ba channel) + 50W (left channel) + 50W (right channel) three-channel output. 2.Support Bluetooth audio reception, external audio input interface, with preamplifier, ba croover proceing; ba volume, ba frequency, left and right channel volume, treble, function control switch / total volume, 5 adjustment potentiometers. 3.Wide working voltage, energy-saving design, efficiency up to 90%. You can use a good performance switching power supply, laptop switching power supply, you can also use a charging bottle, or car power supply, etc... 4.The board is a finished board that has been soldered and tested. Connect the speaker box according to the picture, connect the appropriate power supply, connect to the Bluetooth audio device to play, or connect the sound source input correctly. 5.Bluetooth 5.0 version. The main product parameters: Size (L * W * H): 101 x 100 x 25mm, excluding potentiometer and socket projection Operating voltage range: DC 11-25V(current 3-4A, or 19-24V / 4-5A, such as high power requirements 20-24V / 8-9A above) Note that the DC no-load voltage should not be greater than 25.5V. Bluetooth receiving distance:> 8 m(meters) Audio input sensitivity: 600-800mV Frequency response range: 20Hz-20KHz Speaker impedance:left and right channel speakers: 4-8 ,ba speaker impedance: 2-8 Color: amplifier with case/acrylic case Maybe you jus wantTPA3116 Subwoofer Bluetooth Amplifier. The output power is related to the supply voltage/current, the speaker impedance, and the size of the audio input. When the power supply voltage/current is sufficient, usually the power supply voltage is higher and the relative output power can be made larger. Speakers with different impedances have different output powers. Usually, the speaker impedance is smaller and the power is easier to achieve.

Function switch Instructions for use:

1. Plug in the power on default Bluetooth mode 2. Bluetooth disconnected, long pre the switch can switch to the audio input mode 3. Bluetooth play status, short pre the switch to pause / play
