So, i had a idea to put two optima batteries up front in my 02 gp gt, I was thinking about taking out the air box, adding a cone air filter, making a semi water proof housing for the pcm, then mount a battery on top of It, I would rather not put a battery in the trunk. anyways i was wondering if anybody ever did this before, because if they haven't, i will do a write-up, om also planning on doing a writeup on the big 3 upgrade, and installing a amp 0/1 gauge wiring kit
