Hi David:
These Patio speakers are not wireless. They need a hard wired signal from the music source either the Amplifier or Receiver connected by speaker wire. We recommend 16 gauge two conductor for both the left and right speaker up to 100 foot from the source (14 Gauge for longer runs). The speakers receives the powered signal from the source through the speaker wires. We stock the recommended speaker wire which features a CL3 rating approved for in-wall and outdoor installation. Check out the in-wall speaker wire, CL-3 in 50, 100 and 250 foot lengths under the audio/video cables tab.
