Answer Wiki. The Amazon Echo Dot has a 3.5mm line out so if you have an older set of speakers or stereo system you may want to get a 3.5mm to RCA cable (or others, depending on your speakers). You can also connect Bluetooth speakers or systems to the Echo Dot. If I misunderstood your question and you have passive speakers, you will need an amplifier before you can connect your speakers with the Echo Dot, as the 3.5mm line out requires active speakers.
