Hey guys, I have in my car a aftermarket audio system (4 speakers with a 600w kenwood KAC-8405 and 2 12" subwoofers 1200w each with a pyle 2220-pa 2400w amplifier) and 9 led strips 12v (5 blue strips and 4 RGB strips). I want to make a circuit using TIP31 transistor to make the blue one sync to the base (abviously from the subs). I once made a circuit that I saw on a web site, it worked so great went the music input was from my computer speakers (with a auxiliary plug) and when I tried on my car system, the 2 20amp fuses from the subs amplifier blew off... What do you guys suggest?
