i currenlty have an optima red top and just picked up another new one for free. i am asking how i would go about wiring these two together. i'm gonna mount one in my trunk next to my subs and amop rack. i want to do thios since i have the stereo, winch and lots of auxiliary lights. how would i wire these together so that they both can charge and be useful.

any advice or diagrams would be good.

thanks for all your help.
