wiring problem

My media room was prewired. I had planned on putting buttkickers at each of the seats, however my wiring guys ran 16/2 speaker wire to each seat.

Is there anything I can do to use that speaker wire. Unfortunately we did all of the wiring when the ceiling to the garage, the media room is over the garage, was done for repair, and I really don't want to cut a ton of holes in the drywall. I would like to use the wiring for something with each seat.

any ideas?

thanks.
