I just got a 19 lxs and wanted to run my dual 10" ported box in the trunk. I know I need to run a line output converter, but i am not sure of where to tap the wires from. I am using an LC2i LOC, and i cannot find the speaker wire colors for the back door speakers. Would those speakers be the easiest ones to tap into, or is there an easier way. I would rather not remover the factory radio if I don't have to.
