There was a post somewhere here that mentioned running a dedicated pair of wires off the 12V jumpstart terminals I believe from under the hood, through the firewall, and into the center console area. I forget the post, but I think they were trying to rig a UHF radio or something high powered that needed more current than the 12V accessory outlet.
Some others I think also rigged up a 12V windshield wiper heating system too. I don't know where they sourced their 12V from under the hood, but the wiper heating system came with an inline low-voltage detection feature that would prevent their wipers from killing your 12V battery if it dropped to a certain level.
