installing power cable through firewall for amp

Hi,

Im trying to install an amp in my car. I need to get the power cable through the firewall of my car. I was wondering if anyone knows if there is a predrilled hole that i can get the power cable through on the driver side. Has anyone had any experiences with this.

Any pics?

I actually ran mine down underneath the car in parallel with the fuel lines. Theres two holes you can bring it up through if you do this. Theres one underneath the bench seat in the back where you just have to remove a plug (i did this), and there is another on the passenger side of the trunk floor which youll probably have to drill the insulation out. Either will work.
