Bluetooth speakers are designed to receive audio signals wirelessly from devices like smartphones or computers, while active subwoofers typically require a wired connection to a sound system or amplifier. You would need to connect your Bluetooth speaker to a device that has audio output capabilities, and then connect that device to the active subwoofer using the appropriate cables. **

Once connected, you should be able to enjoy surround sound audio wirelessly from your device through the Bluetooth jack. **
