The Amazon Echo Dot 5th Generation can be connected to external speakers or a stereo system, but it does not support a direct wired connection for true stereo sound. Here are the ways you can connect it:

- Bluetooth: You can pair the Echo Dot with Bluetooth speakers or a stereo system to stream audio wirelessly.
- Multi-room audio: You can also use the Echo Dot as part of a multi-room audio setup with other compatible Echo devices, allowing you to fill your home with music in different rooms.

However, for a traditional wired stereo connection, you would need to use an external adapter or converter, as the Echo Dot does not have an audio output jack.
