It is on the driver's side as well because I ran my RCAs down the passenger and my 1/0 down the driver side. What is the problem with doing it this way? There was a pretty nice size hole on my firewall which just had a rubber plug in it, I took that out and I'm sure I could have got two runs of 1/0 through it.It's a '97. I know I have a cable channel on the passenger side, but I'm not sure about the driver side.
