Be sure to connect speakers firmly and correctly according to the channel (left and right) and the polarity (+ and -). If the connections are faulty, no sound will be heard from the speakers, and if the polarity of the speaker connection is incorrect, the sound will be unnatural and lack bass.
After installing the speakers, first adjust the speaker settings according to your environment and speaker layout.
