(They seem to have never heard of resistors.) That should be sufficient to allow you to hook up both light box and amplifier to the audio output. And swap that TIP31 for a BC337-40. The TIP31 has almost zero current gain (HFE). C goes to the left LED's -, B goes to the resistor you added to the red wire, and `E' to the orange wire.

Audio frequencies turn the LED on and off so fast you can't see it go off. You need to change the parameter of the audio signal to get a useful response. This is usually done with a rectifier, a capacitor, and a resistor to form a time constant slow enough for you to see the amplitude change.

The circuit would be powered and light up the LED, but be controlled by the audio signal. Okay, so the 'power supply' part would have to be controlled by the varying AC voltage of the audio signal. Let's just establish some numbers for the LEDs to make the discussion consistent: 2600mcd intensity, forward max voltage 3.3V, forward max DC ...
