Locating battery to trunk?

The cement floor thing is a myth. I let my battery sit on a cement floor for 4-6 months every winter and I don't have any problems.

I think it has more to do with what leaking acid does to the concrete floor. I always just put a small piece of wood inbetween.

You don't need to run a neg. cable to the front. The continuity of the car frame is more than any reasonable size cable you might install. Just run all you negatives to chassis.
