Well, I'm not a audio hooker upper but i watched the guy put mine in and all he did was open the driver door and hood, take it from the battery to around by the windshield wipers (under the hood) then on the right there's a little daylight to sneak the wire from the hood to inside the door along the door frame and under the driver side panel (take it off of course), tucked it under the panel that's connected to the seat belt, under the rear panel then through the backseat through the corner portion of the seat that comes off partly. I hope that can help you a little and if theres something else, I'll tell you if I know it. My friend has a 95 explorer and yesterday they told him he would have to drill a hole in the firewall to get his 4 gauge through because he didn't have any hole between the hood and door. I laughed my azz off!
