Thanks for the information. However, I was already aware of this method. I HIGHLY discourage anyone doing this. It is MUCH more prone to damge because it's exposed in the fender (lots of things can happen there such as flying rocks and possible weathering) and a lot of people then run it down the hood jam as seen in this http://www.jwardell.com/focus/amp.html which is a hazzard. That's why I discourage this method so greatly.
