Using the NEXO MSUB18 - I subwoofer is easy. First, connect the short cable with bare wire ends to your audio system. The included VNI - BUMPM12 Fly Bar can be used to mount the subwoofer if needed. When using, place the subwoofer on a stable surface to avoid any shaking that may affect the sound quality. Make sure the connections are secure to prevent any signal loss. For maintenance, keep the subwoofer clean by using a dry cloth to wipe off any dust regularly. Avoid exposing it to extreme temperatures or moisture as this can damage the internal components.
