The red and gray ring inductors are specially designed for digital power amplifiers, while the 684 film capacitor is a special capacitor for audio amplifier, so both of them are features low loss, high bandwidth and high fidelity.
With AUX and bluetooth two audio source input mode, two in one.
With a switch, potentiometer can be used to adjust the volume, easy to control the volume, very suitable for DIY speakers.
Copper DC female head, fence terminal, withstand large current, no heat, no damage to the line, good wiring, not easy to short circuit.

Tip: To have enough output power if the audio input is sufficient and the supply voltage/current is sufficient. The power supply voltage is higher and the relative power will be larger. The speakers with different impedances will have different output power. In the case of sufficient voltage and current, the larger the ohms of the horn the smaller the relative sound power. Please pay attention!
