hey guys i have a crx that i am contemplating putting a turbo kit on, well as we all know that there is not too much room to fit a turbo in the engine bay of a crx. so i want to relocate my battery to the trunk, i already have 4gauge running back to my amp, i was wondering if i could just use that 4 guage to run the batter from the trunk instead of using it for my amp. or do you guys think I should just go all out and replace it with a thicker gauge wire?
