contuor amp power wire problem!!
 

hey i have a 98 ford contour se, its the 2.5 ltr v6, and im trying to find a hole in the firewall to run a main power wire to my amp for my subs, i worked on it for like an hour, but ended up where i started, all my other wires are ran to the trunk and im just trying to get this last one in and done, so when winters over i can just plug in my subs, any help or hints would be greatly apreciated, thanks yall.
