Default Easiest place to route power wire for amp through firewall area?

I've been dicking around outside looking at a easy place that I wont have to drill for the last half hour, so far I've concluded to run the power wire off the positive terminal on the fuse block on the driver side then route it through the dash somewhere through the plastic cover that has the wires with the rubber gromment on it up top but I can't find where this leads to without taking apart my dash...
Is there an easier passage that I'm not seeing?

out of curiosity anyone have a pic? im gonna do this in the summer and i was looking but didnt see a place. is the computer behind the glove box?

oh and just a note running an amp off the fuse box is BAD. but you should have a fuse in the wire right next to battery. not saying u didnt with the fuse but anyone reading this thread should see the point that you cant run off the box and you use a separate fuse.

the actual PCM is in the engine compartment, passenger side, tucked underneath the cowl. you can't miss it.

I had that routing on my last car and it was a pain in the butt when I wanted to pull the wiring out on the engine harness (and then you still have a big power line running over the tower). this time around, I took the wheel well cover off and routed the wire underneath and drilled a hole into the car right below the area where the PCM wires go through (but inside the wheel well instead). Wire is routed from the battery into and over the fender and into the firewall. This way, when I finally get around to doing the wire mod, everything is out of site.

Good Idea, I might check this out when I do mine, thanks!
