After such as helpful result from my last question I was able to complete that little job and now onto the next one.

Running power cable from the engine bay to the cabin in a BA-BF falcon. The next upgrade is to add a sub and power amp so I'm looking for suggestions on alternatives for the power cable through the firewall. I won't be runnning huge power so I don't need much more than 8 guage cable. Looking for the laternatives and pics of possible.

is it an auto ? if it is then whats wrong with the clutch cable hole ?
