Alright, I'm installing an amp. I know all that is needed to know about wiring it up. I'm just trying to figure out how to get my 4AWG power cable through the firewall without having to resort to drilling a hole of my own. I'd prefer to run it along the left side of the car cause thats whe side the battery is on.
I had a look around and found me two holes that I could possibly run it through...
The first is the obvious route:
But I'm worried about interference with those other wires, which look like they have alot do do with controlling how the engine runs. I also don't know where this hole ends up on the other side.
Next route is going almost under the car:
...But at least I know where it ends up on the other side:
My main concern about this route is that it goes under the car a bit, and it'd be a pain to get it through there and try to secure it so it doesn't move around. It'd be exposed to the elements a bit more aswell.
So which way would be better? I'm thinking it'd be the second, but what do I know?
Or would it be better if I just drilled a hole of my own? (That's the last thing I'd want to do.)
