Model: ZK-TB21Chip: TPA3116D2 (With AM interference supperession)Bluetooth Version: 5.0 (Without occlusion 10m)Audio Input: AUX + BluetoothChannel: 2.1 StereoAdaption Supply Voltage: 12-24V / 5A aboveSpeaker: 20-100W, 4-8OhmOutput Power: max 50W R&L channel; max 100W subwooferProtection Mechanism: overheating, undervoltage, overheating, DC detection, short circuit protectionTip: 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 ensure that the power of the adaptor is greater than the actual working power of the amplifier.
