OK so to get down to the nitty gritty, what you are going to do is first take off some panels. You want to take off the kick panels, the panels running along the door, not to be confused with the side sills if you have the aluminum ones especially, the ones for the back also, and the plastic retainer that covers the seatbelt, that about 3 foot long piece. these are all pretty easy, just carefully pry them off with a panel popper. Do this on both the driver and passenger side.
Once that is done, you are going to want to remove the backseat. To do this, fold the seat down, and there are lil velcro covers in the lower corners that get peeled to the side to reveal 2 bolts, there are 8 in total, 2 on one corner, 2 in the middle corner, and same for the other passenger seat. I can't remember off the top of my head which side has the middle seat belt attached, but you will not be able to pull that seat out until you detach the seatbelt. Remove the couple of bolts holding the backseat down, and carefully but forcefully (with a buddie) one on one side, and one on the other from the front facing the rear, as not to ruin the seat, PULL STRAIGHT UP! If not done carefully, you could mess up the padding, but with just enough force at the same time, you will pop it out easily.
I personally did not remove the front seats as it is for 1. time consuming, and 2. I am so good at installs at this point, most small compacts do not need the front seats removed for me to run wire.
Remove all of the center console panels, which you will start from the back removing panels and nuts, pretty self explanatory if you have ever done a stereo install.
To run your wire, WARNING!!!! ALWAYS BE SURE TO RUN SPEAKER WIRE AND POWER WIRE ON OPPOSITE SIDES OF THE VEHICLE AND NEVER RUN THEM NEXT TO EACHOTHER!!! I would think that running your mid/high amp would be better suited under the passenger side seat since that is better confined away from where the power wire will be on the driver side.
First run your power wire from the engine bay, if you read my FOG LIGHT HOW TO sticky at the top of the page that will give you a great plan to run your power wire through to the engine bay. Run that power wire down and through the crevices of the foam underneath the carpet. If you don't have a wire snake than I suggest you remove the front seats before contiuing, or recruit a young teenager with long skinny hands. You will either run the wire snake from the middle where the center console was, down through to the driver side door, underneath the carpet of course. Grab your power wire and pull, if not have the skinny armed test subject grab the wire and shove it through to the middle and have somebody grab it somewhere near the middle, or near the end. do the same to get the power wire underneath the passenger seat, no need to cut holes in the carpet, run all the wires through the stock opening where wire looms are already there. do the same with a short strand of ground wire, and ground to the huge parking brake nuts.
For your remote wire, grab it, run it down through the center, and under the carpet of course, under to the seat.
Your RCAs are now going to be run in the same sense as the power wire, BUT!!! RUN THEM ON THE PASSENGER SIDE. under to the stock slits.
Pop off your door panels and remove the stock speakers, with your panel popper and a microfiber cloth, pop off the door handle & window control piece off of every door. CAREFULLY AS TO NOT BREAK THE PLASTIC SHROUD ON THE DOOR LOCK, jiggle it until you hear it unsnap, these are VERY VERY fragile and will break VERY VERY EASY please becareful, I did snap one of the grabs by accident on my very last one I did, isn't that nice! And the dealer that has some idiot install the window glass break sensor for my alarm system broke one of the grabs on the driver side, which was the first one I pulled off and was easy. This is how I figured out how they were held on and break easily. Once those are off, there are two nuts in the handle area to take off in the front doors, and one nut to take off on the back doors each. once those are removed, with the microfiber cloth and panel popper, carefully start at the bottom and pry off the panel, once it is loose, lift UP and OUT.
Remove the 3 screws and connector holding the stock speakers.
Now the fun part once all of the panels are removed. Have yourself a nice industrial size zip tie ready, the nice big long ones that are about 3 feet long, you can cut it down to about a foot and a half if you would like, just be sure to cut a rounded edge. Cut off the box end where the zip tie is usually inserted. Tape your wire to the side the box used to be on. Now pull off the rubber protectors between the door and the frame, carefully as to not yank em and cut wires. These rubber gromets are there so that they protect wires from being rubbed against the bare metal, and wearing off the rubber protection of the wire and possibly causing something or even your whole vehicle to short out. So with the zip tie run it through the grommet which is going to be a REAL P.I.T.A. but you will get it, it takes time and patience to route it through without ripping the grommet, if I can do it, you can too. run it through the grommet, and snake it through the frame to a nearby hole, this will be easy to do once you see everything apart and are doing it. Route your wires, leaving enough wire everytime to replace the grommet, and run some to the speaker with enough slack, but not too much. Do this for all 4 doors. On the driver side when you run the wires, run them through to the back of the car, and up and over the rear hump, behind the plastic bushings that hold the rear seat in that you will most likely struggle with pulling the seat out without f***ing it up. No I didn't mess mine up!
Once that is done, install your speakers, and hook up your amp, connect the battery 12v+ constant, and finally fuse it appropriately. Do your tests to make sure all is ok, and put it all back together, and do your final sound tests, and adjust it properly.
Any other questions feel free to ask.

Run the wires to the doors by snaking them through the exact same path the existing wires run. While putting the carpet back in, cut a small hole to allow the wires to pass through, and you'll be all set.
If you wish to completely gut your interior and waste precious time, then feel free to, especially if this is your first install, as this may actually SAVE you time rather than waste time.
By all means please do not listen to BBISHOPPCM when he says to run your wires next to the factory harnesses. Unless you are paying hundreds of dollars for very expensive high end car audio wire like Monster cable of other high end shielded car audio cable, never do this. You could potentially pick up alternator whine from power wires by doing this, which is the really annoying whine you get that gets louder the higher the RPMs are.
