i recently installed a new head unit and i have connected the subwoofers via the rca outputs in the back. we have matched up the speakers according to the chart on the old head unit and the one on the new one (e.g. LR+ to LR+). however there are a few wires remaining that are labeled PARK, ILL, MUTE, ANTENNA. we left these wires unhooked since we didnt have a corresponding wire on the new head unit. the subs work fine but the door speakers arent. what should i do?
