I have a pair of 3 Watt 8 Ohm speakers.
- 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?
- I want to connect directly to raspberry pi. How can I do that?
- 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.
1Ah, let me see. This long story might help: raspberrypi.org/forums/viewtopic.php?f=91&t=224976. – tlfong01 2 hours ago

1And if what you want is to play mp3, this might help: “How can I start an mp3 from the beginning every time a headphone is plugged in?”: raspberrypi.stackexchange.com/questions/106684/…. Cheers. – tlfong01 2 hours ago
@tlfong01 . Thanks. ANy idea on how and where to connect the red and black wires coming out pf the speaker ? – NeedSomeLuck 1 hour ago
You need to connect an audio amplifier between the audio out on the pi and your speakers. – CoderMike 36 mins ago
Yes, as @CoderMike says, you need to use an audio amplifier such as PAM8403: References: (1) Raspberry Pi Zero Audio Circuit – OtherMod 2017jan31 othermod.com/raspberry-pi-zero-audio-circuit (2) PAM8403 Filterless 3W Class-D Stereo Audio Amplifier image.dfrobot.com/image/data/DFR0119/pam8403.pdf – tlfong01 32 mins ago
And the Rpi 3.5mm to PAM8403 > 3W speaker x 2 connection is like this: Connection: (1) Rpi 3.5mm jack(A-5/013) > 3.5mm plug to PAM8403 power amp module, (2) PAM8404 power amp module to 3W speaker x 2 (JST-PH2.0 x 2 connector). – tlfong01 21 mins ago
But the Rpi 3.5mm PWM audio (100Hz to 5kHz pass band) is not very HiFi. You might like to consider using a good quality 20kHz bandwidth USB sound card as suggested by my very first and second references: (3) raspberrypi.org/forums/…. The US$12 cheapy Ugreen USB sound card can select the following modes: (a) HiFi raw, (b) music, (c) film (surround sound), (c) computer gaming to suit your applications. – tlfong01 5 mins ago Delete
