power LED strips via car battery? Answered

I've got a little project where I'm installing RGB LED strip lights in and around my car. They are 5 volts strips and looks like it'll require up to 10 to 12 amps for the total installation. Can I use the car battery to power this? If so, how do I go about doing this?

looks like you're right. I can't get a big regulator here in time for my project, but I can get a bunch of small ones. Do I connect all 6 small regulators directly to the car battery? I imagine that's bad practice

run them in series pairs, on 12volts, and put two forward biased diodes in series with each pair.
