i am installing subs into my 2001 ford taurus. i have all of the wires ran except for the power wire to the amp. how do i run that to the battery? i cannot seem to find where all of the cars wires run through the firewall. does anyone have any idea. if not, where would be the best place to run the wire through the firewall?

I own a 2002 Ford Taurus, which I already installed an after market radio in. I'd like to install a 4 channel amplifier in the trunk to drive new speakers I also plan on installing.

I understand that I need to run a wire from the battery to the trunk in order to power it, but I am not entirely sure how to get it through the firewall of the car. I have read generalized instructions that say to look for an opening where wires are already coming through, but I can't find any. I have also read about drilling through the firewall and installing a rubber grommet, but I am not entirely sure how to go about doing that because there does not seem theres any good places in the area between the bottom of the dash and the floor.

So basically if anyone here has installed an amp in their Taurus' trunk, I'd like to know how you did it. Or, perhaps there is a website that could give me some ideas?

I nedd to know the correct firing order for my ford taurus 2002 se v6 sohc i looked at the diagram under the hood i know for sure the ones in back closet to the firewall are cyl. 1,2,3 passenger middle, driver but the rest i cant make out are they in order to or are they??
