Connect the left and right speaker outputs to compatible 4Ω–8Ω speakers. Select Bluetooth, USB, TF/SD, FM or AUX according to the desired audio source. For maximum advertised output, a suitable 24V high-current power supply is recommended by one vendor; at lower supply voltages, available output power will be lower. 📦 Package Includes 1 × Gold AP-55 TPA3116D2 2×50W Bluetooth Amplifier Board 1 × IR Remote Control 1 × Required Connecting Wires/Cables (package contents may vary by seller/version) ⚠️ Precautions Verify the exact input voltage requirement of your AP-55 version before powering it. Do not exceed 24V DC where the board specification limits input to 24V. Check power polarity carefully before connection. Use speakers with a compatible 4Ω–8Ω impedance. Do not short-circuit the speaker output terminals. Ensure adequate ventilation during high-power operation. Use a suitable high-current power supply for high-output operation. Do not connect the speaker outputs together or directly to ground. Keep the board away from moisture and conductive materials. Incorrect wiring or excessive voltage can permanently damage the amplifier IC.
