Amp power wire I have read on here that the best place to run the amp power wire is on the passenger side below the PCM, now forgive me if this has been asked to death but where exactly below the PCM is the hole? Do you need to remove the PCM to get access to this area or not? I have looked at this area many times and I cant see squat 
, If anyone can shed some detailed light on this I would greatly appreciate it

Take the PCM out. You'll need a 10mm socket for the bolts holding it down, and a 7mm socket to remove the actual harnesses. You'll have to kinda rotate it about 90 degrees to get it out. Once it is out, you'll see a rubber grommet down there. That is what you are looking for.

The rubber grommet is on the firewall, you'll want a flashlight handy to see it easily. It already has a wiring loom poking through it, you'll just shove your fatty amp wire through there as well.
Don't forget to fuse it close to the battery, and check that the wiring doesn't intefere with the hood or rub up against anything sharp.
The PCM is a little finicky to get out of it's hole. If you've never done it before it will take a bit of wiggling, and remember to take a mental snapshot of how it comes out, because you'll have to weasle it back in the same way.
Because it's outside, the fasteners can be pretty stubborn, as well, and they are pretty long.

You don't want to overload that distribution box (fusable links, overheated factory wiring, all sorts of bad things can happen). That wiring isn't designed to support the additional amperage a large amp can pull.

I wouldn't recommend that setup through the factory distribution block. I guess you are getting away with it, so it's hard to argue against it, but if you overload that distribution box it would be a very bad thing.
I don't think a single person in car audio would recommend running two decent amps like that without a fused line to the battery.
