Using the Bose Bass Module 500 is super easy. First, make sure your soundbar (either the Soundbar 500, 700, or Soundtouch 300) is turned on. Then, connect the bass module wirelessly to your soundbar. Once connected, you're all set to enjoy amazing bass in your music and movies. When it comes to placement, you can hide it anywhere in the room because of its compact size, but make sure it's not blocked by large objects. As for maintenance, keep it clean by using a soft, dry cloth. Don't expose it to extreme temperatures or humidity. And if you're not using it for a long time, it's a good idea to turn it off to save energy.
