A:Answer The radio has a single 3.5mm external jack so you run a male-to-male 3.5mm wire to your sound bar and use the remote on the sound bar to select the XM as an input. You can also use various aftermarket 3.5-to-Bluetooth transmitters for $20 or so and then broadcast to Sonos, Bose, etc Bluetooth enabled speakers. Pretty easy to set that up.
