I have seen pictures of people running car batteries, after relocating them up front. Running two batteries with an isolater would be a great set up but a little more difficult to do. This would keep your starting battery charged and run the extras from a deep cycle battery.
If you are trying to run a stereo and a couple of extra lights, get the biggest AGM battery that will fit in the stock location.
