The wiring of the four terminals of the speaker is the same as that of ordinary speakers, and there is no difference. There are also corresponding signs on the machine. Just connect the speakers according to the signs.

First, reshape the four wires of the two speakers, peel off the ends of the wires by one centimeter and cut them with scissors. Connect the black lines of two lines marked with L or lines marked with negative sign in the speaker to the terminals marked with negative sign on the left side of the four terminals of the power amplifier. Connect the red line or the line marked with plus sign in the two lines marked with L to the terminal marked with plus sign on the left side of the four terminals of the power amplifier. Connect the two lines marked with R or the black lines marked with negative sign to the terminals marked with negative sign on the right of the four terminals of the power amplifier. Connect the red line or the line marked with plus sign in the two lines marked with R to the terminal marked with plus sign on the right side of the four terminals of the power amplifier.

The wiring of speakers must be one positive pole and one negative pole for each speaker, and it is not allowed to connect two positive poles or two negative poles for a speaker at the same time.
