Connect across speaker and LEDs should flicker in sync with music you don't need 4700  uf  just 100uf and leds and 330 ohm resistor you may need to experiment with this resistor increase its value if LEDs are to bright  and 100 uf  you could use different coloured LEDs to a get nice effect   

Tested and found 1000 uf  capacitor  a 1 watt cool  white Led with 10 to 50 ohm gives good results I also have a high powered surface mount led connected as well and it looks good light output is in sync
