I am wiring LEDs to my subwoofer to sync in beat of the music, to stop the bulbs from blowing, i am thinking of wiring a TIP31 transistor to it and plug in RCA and 12v in to run it using a rca out to the actual amp,
in the attached picture please make sure i got all the wiring right and tell me if it would work

and sorry if this is in the wrong section
edit:
also should the LED's run in a series or parallel?
