PUSOKEI TPA3116D2 100W Amplifier Board, DC 12-24V Stereo AMP Audio Amplifier Board, Digital Sound Power Amplifier Module PCB Board for DIY Speakers Subwoofers

Specification: Item Type: Amplifier Board Material: PCB Input Voltage: 12-24V Output Power: 100W Input Frequency: 20Hz-20KHz Output Frequency: 20Hz-180Hz Sound Input Sensitivity: 500mV Subwoofer Impedance: 2-8? Package List: 1 x Amplifier Board 1 x Adapter Cable 2 x Knob Cover 2 x Gasket 2 x Nut Note: 1. The output power is related to the power supply voltage, speaker impedance, and sound source input size. Usually the higher the supply voltage, the higher the output power supported. 2. Speakers with different impedances can support different output power. Typically, speakers have less power and are easier to implement. 3. Components may vary slightly from batch to batch, but functional performance remains the same.
