Ok, i have to ask you guys a stupid question. I know some of you guys have massive amounts of 12v goodies hooked up in your cars. What i ask is, where do you find all the power sources for these things. I have a video screen, dvd player, and tachometer hooked up and it was a strain to find switched 12v power. I would just run it directly from the battery off a distribution block but i dont want everything to stay on after i shut the car off.
