Using the JBL VRX918S subwoofer is easy. First, connect it to the correct power supply that comes with it. Make sure the power source is stable to avoid any interruptions. When setting up your sound system, place the subwoofer in a position where it can spread the low - frequency sound evenly. To keep it in good condition, clean it regularly with a soft, dry cloth. Avoid exposing it to extreme temperatures or humidity. Also, don't overload it with too high a volume for a long time, as this may damage the speaker. If you have any problems, consult the JBL customer service team.
