A:Answer Yes, if your Rocketfish outdoor speaker has Bluetooth capabilities, it should work with our Rocketfish™ Bluetooth Audio Receiver. The receiver is designed to connect to wired speakers or audio systems and receive audio wirelessly from Bluetooth-enabled devices like your phone or tablet. You would connect the audio output of the Bluetooth receiver to the input of your Rocketfish outdoor speaker using an appropriate audio cable (like RCA or 3.5mm, depending on the speaker's inputs). Then, you would pair the Bluetooth receiver with your audio source (phone, tablet, etc.). The audio will then be wirelessly transmitted from your device to the receiver, and then through the cable to your outdoor speaker.
