Going to a lot of car shows, I have noticed that most people have a large 12V supply (large, like 30-40 amps) underneath the car. I would assume that these come from audio shops at a pretty hefty price. If you are electronics oriented, you can make one yourself very easily. It doesn't even really need to be regulated, just able to supply 30+ A at around 13V. An old microwave transformer can be rewound to supply the proper voltage/current very easily.
