Description:The potentiometer adjusts the volume, with a switch, it is convenient to control the volume, which is very suitable for DIY speakers

If it is a metal box, the Bluetooth antenna needs to be led out

The copper DC connector is used, which can withstand high current and does not generate heat

Capacitor 470UF35V solid capacitor, to ensure the power storage and heat dissipation capacity, providing stable and continuous is the prerequisite for good sound quality

The 5

0 Bluetooth version has higher transmission efficiency and longer transmission distance

0Bluetooth transmission distance: 15 meters (unobstructed)Protection mechanism: self-recovery overheating protection, self-recovery short-circuit protectionPower supply voltage: 12V—8 ohm speaker/12W (left channel) +12W (right channel), 4 ohm speaker/20W+20WPackage Includes:1 x Bluetooth power amplifier board1 x Enclosure accessories1 x DC cableNote:Tip:Only when the audio input is enough and the power supply voltage/current is enough, there will be enough output power

The higher the power supply voltage, the higher the relative power, and speakers with different impedances will have different output powers

In the case of sufficient voltage and current, the greater the ohms of the speaker, the lower the relative sound power, please pay attention
