Geting wire through the firewall

What are some options for getting power wire through the firewall? I am probably going to run a number 6 for a 400 watt inverter and a 115 watt audio amplifier.

There is an unused penetration pretty high up on the firewall. I havent checked into this one yet to see where it comes out.

What choices do I have that I have not considered yet? I assume the passenger side is best because of the proximity to the battery.

Remove the battery and you will find a rectangled/oval looking plug. That is where I ran the wires for my power. The wires will come out above the Passenger kick panel. And I have an 06 as well, so I know it works

I noticed the holes you were talking about. They are somewhat filled by the fuse box wiring. I tell you installing wiring in this new F150 is tuff. Under the dash and under the hood is tight. I think only 5 penetrations in the firewall. The ones that are not used on my XLT are very high up and hard to get to. They do have plenty of space in the center of the dash near the radio. The all electric heater/ac controls make that possible.

The big driver's side plug is where I ran my antenna wires.
