Dennis • 03/27/2020, 0:24:03 AM Can I sync them with my indoor tv?
Customer Service • 03/30/2020, 1:23:12 PM
Hi Dennis: In order to sync these speakers with your TV you will need to check to see if your TV features a Bluetooth Transmitter. When I googled that question, recommendations came up for external Bluetooth Transmitter/Receiver dongles that could be added to your TV. There were a lot of choices. So check with the owner's Manual for your TV, look for Bluetooth Transmitter option. Here is an example: Good luck TimL: 3-30-01
Rachael • 05/22/2020, 5:29:26 PM Hi are These speakers wireless or Do they have to have wires to charge ? Also do the speakers pair Together ? Thanks
Customer Service • 05/28/2020, 11:46:12 AM
Hi Rachael: There are two speakers with the kit. The first is the Master Rock with a 5.25 Dual Cone driver, Bluetooth Receiver, and 60 watt stereo amplifier. This needs a power source so there is a Waterproof 24 Volt Power Supply with a 20 to 25 foot cord that needs to plug into an AC outlet at one end and the Master Rock at the other. One channel of the Stereo Amplifier is connected to the internal speaker. The second or Satellite Rock is connected to the Master Rock by a Two conductor speaker cable that creates a right and left stereo pair of rocks. You only sync up the Bluetooth Receiver in the Master Rock. The only thing that is truly wireless is the Bluetooth connection from your Device to the Master Rock. There is no charging involved since you have an AC power source connected full time. TimL/5-28-2020

Customer Service • 06/05/2020, 3:20:27 PM
They are wireless between the Bluetooth enabled device you are using and the Master Speaker which has both the Bluetooth Receiver and a internal stereo amplifier with one channel connected to the internal speaker. You then have to connect a two conductor speaker wire (included in the package) to the satellite speaker from the master. You also need to connect the AC Power Supply from an AC outlet to the master Rock to power both the Bluetooth Receiver and Stereo Amp. Wireless only refers to the Bluetooth device to the Master Speaker. TimL/6-5-2020
