Dear Community,
In raspberry pi 3 B+, can I connect its “4-pole stereo output and composite video port” into two speakers (8ohm 1w) safely using wires and connectors only, I mean without amplifier or resistor… ?
Actually I saw the following blog, they used MAX98306, so do I need it ? http://blog.whatgeek.com.pt/2015/04/give-your-raspberry-pi-the-power-of-speech-with-adafruits-max98306/
Yes, if you wire them correctly:
But you won’t hear much because the power provided by the jack is much too low for passive speakers.
Buy the amplifier or an usb sound card, or even better a PiHAT to get sound out of it.
This is only ONE example for an audio hat, there are a lot more on the market.
What about PAM8403 did you try it ?
Yes, but not with a Raspberry.
can you please say why not ?
I don’t have any usecase for sound on my RPi 
I’m using that amplifier to drive additional passive speakers for my TV.
