Hi, i need some help.. i just bought a 2004 kia optima lx and i'm hooking up a sound system. only problem i have is running the power wire from the battery to the trunk. I can't find any holes where to run the power wire. i installed a few systems in my cars over the years and never had this problem. i can't find any holes to run the power wire so my next option to drill a hole in the firewall.. so where would be a good place to drill a hole? if any pictures are needed i can take some.
