KB64A/B/C(E) Bluetooth Module 6. Design Note Except KB64A, the KB64B/C is design for stereo speaker output, SPKR_RN, SPKR_RP, SPKR_LN, SPKR_LP are output for stereo audio output. If it connects with amplifier, it must be differential input. Or, it must have a component to balance two signal levels different. Otherwise, it will cause pop noise. You could refer the reference schematic for more detail. When using KB64A, please not connect the SPKR_RN, SPKR_RP for mono output SPKR_LN, SPKR_LP only.
