I haven't had another chance to check for the 12v again. I had already tried to find a 12v that's what I was referring to. The LED to speaker was a question for a Sub box I am building. I was thinking about LED the pulse to the music. I know they have modules that do it, but I was wondering. But I would like to thank those who stood up for me. I know I'm not an expert, but the kid who wanted me to hook these up knows that too, but it is s hell of a lot cheap than most shops. The Duals I put in a Blazer, 5 months and the LEDs still work. Not the best sound quality but they light up. lol. That's all some people care about.
