1. Outdoor Bose speakers mounted on the house use a old Harmon Karden amplifier as I stream music through my phone. You can add a blue tooth connection to older stereos for $20-$30. I need the power as I have a pretty big backyard and I like to garden. I also crank it when the bratty kid behind us crys (daily basis). I am doing a psychological experiment on him to try to teach him to shut up.
2. Living room....or family room place.....not sure what you call it. I have a Bose CD player on bookshelf that I added blue tooth connector. Again I stream through Sirius or Spotify.
3. Bathroom I have a portable speaker I stream through.
4. Office. I have Bose speakers with subwoofer connected to my computer.
5. Garage. I moved out to the boonies so I have a huge 4 car garage. I converted 2nd part into a gym and I use my old Denon receiver with a pair of Polk bookshelf speakers and Polk subwoofer to stream music through when I lift (which hasn't been that often lately). Drowns out the weird noises I make.
