I second deadhead. At the bare minimum you need an amp and a device that can accept either Bluetooth, AirPlay, or Chromecast, which are the wireless ways to send music. Are you sure that you can’t clean out some of that stuff to make room? My suggestion would be to get a pair of speakers that come with a Bluetooth receiver and amp built in. My suggestion would be Audioengine.
Later after you clean out the space a little, and if you really want to use the VA speakers, I would by a small integrated amp that includes a device that can receive one of the three technologies listed above
