I have a pair of 3 Watt 8 Ohm speakers.

My questions:

  1. I want to connect it Raspberry pi 3. How can I do that? From the speaker 2 wires are coming out - one red and one black. Where do I connect these 2 wires?

  2. I want to connect directly to raspberry pi. How can I do that?

  3. To what pins of Rasp. Pi I need to connect this speaker?

I know that there is (already) an audio jack on the Raspberry Pi board. I only want to to know the steps for connecting the speaker to it and getting some audio output.

You need a stereo audio amplifier between the Pi’s analogue audio out and your speakers.

If you’re ok soldering something like the following should work and could be powered from the Pi’s 5V.
