Hello im facing this problem, the AUX port on the right speaker is louder compared to the AUX port the back of the subwoofer. Im not using any adapter. I just connect the AUX to the both ports and to my laptop and just tested with a bass song on youtube and i can see the difference of sound and bass from the both AUX port. Can anyone help me to solve this problem? why the sound is different on the both AUX port??
