need help instaling

I am just trying to hook up a simple amp just for my 6 1/2 in the rear. i am not sure hot to go about running the power wire and rca's. AM i supposed to drill the whole in the firewall? Any help would be good or i will just pay somone if anyone is interested in doing it and lives close enough to help me out. i would go to the shop but they won;t let you watch and i want to learn how to do it myself.

There is a rubber gasket on the passenger side of the firewall, you should be able to push a wire through if you take a metal coat hanger and unwind it so it's a really long piece of metal. Just poke the wire through and then run it to where ever you need.

After you get the power wire though, run the rca's and wire under the carpet and then put them up through the plactic piece and snap it back in.
