Thanks for the question, and welcome to the community.
Which system are you looking to use your Fire stick with? If the system has an HDMI input, you may be able to use it.
Let us know so we can help out.

Thanks for the reply.
You may be able to connect the Fire stick to the HDMI in on the soundbar then run the HDMI out to the TV for video, however you may experience some HDCP issues. I would recommend connecting the Fire stick directly to the TV and using ARC from the TV to the Bose.
Please let me know if you have any more questions.
