LM386 speaker + LED help? Answered

How would I go about making a speaker out of an LM386 which has lights that pulse to the music? is there a simple schematic to go by? all the ones I've tried work, but the 8 ohm speaker sounds drowned out and the leds just stay lit or burn out

Put a 50 Ohm resistor in series with TWO LEDs, put the two LEDs in parallel, but in reverse, so the Anode of one goes to the cathode of the other, the cathode of one to the anode of the other.

Did you put a series resistor on the LED?

I've only been working with circuits for about 3 months now. So im not really sure how to do that, as embarrassing as it is to admit. im using this schematic https://www.instructables.com/id/Portable-Speaker-1/step4/Observe-Diagram/
