Where in the firewall did you run you amp's power cable from the battery under hood to the trunk?

Going to make it out today to cable.. heads up ont his if you would.

 

I have mine threw a spot that a lot of other wires run threw on the drivers side and it works fine but theres a bulge in the carpet so what I think would look better would be running a corregated line under the car and try to find some kind of plug or hole to run it into the trunk

 

there is a grommet near the top of the firewall on the drivers side. Make a cut in it and push your cable through.

Corregated? NEver heard of that in a car.....
