Is there a good or "Easy" place to drill a hole through the firewall for power to an amp? 2013 FIT.

 

Ar least in My '08 GD there was a large rubber plug on the passenger side that I was able to open, enlarge and pass the cable through. Try to work with an existing hole, or make sure you add rubber grommets to insulate it of you decide to make your own!!!

 

Check around your A/C hoses going into the cabin there is a rubber grommet that you can slide wires around to go inside.
