I just ordered my subs, and was planning on running the cables for my amp this weekend. I was looking under the dash and under the hood today, and I can't find anywhere to run the power wire through the firewall. Is there already an existing hole, or do I have to drill one? and if I have to drill, where can I do that? My car is a '99 with a Duratec. If anyone can explain this to me, I'd appreciate it, and if I could see some pics of how somebody has run their wires, it would help even more. Thanks.
