Forgot to mention that you'll need the usual ratchet & sockets along with a good sharp pair of heavy duty scissors and a phillips and flathead screwdriver.
First you have to remove ALL your interior parts. It was pretty straight forward for me, because I've done it quite a few times. It generally should be the same for most Honda's as the setup are very similar.
Unbolt the front seats (usually held down by 4 bolts)
While they are out, you can easily remove the center console (shifter area, under the radio, and the armrest)
Then remove the rear seats, again, depending on what seats you have, it may requre a slew of different tools. This is also a great time to clean the seats if you haven't done so.
Along with the rear seats, you'll need to remove the side panels that hold the carpet down, under the door sills. Remove those- which are stapled and hooked onto the carpet with metal discs. At this point, you may or may not want to retain the plastic pieces that attach to the carpet from the door sills. I opted not to reuse them as they were pretty beat up already. I think it is better to keep them and remount the carpet to them for a more secure fit.
This is what you should clear out the interior to:
You also may have to remove the trunk/gas release cover which is held by one small screw under a plastic cover. (Forgot to mention that a Helms manual is handy).
After you remove the OEM carpet, which is held down mainly by the door sills and under the rear seat area, you should try to get rid of most of the garbage/particles and then lay it over the new carpet. Also vaccuum the inside of the car so you get a clean surface.
As you can tell, there's a lot of trimming and cutting to be done because the new carpet is totally uncut. Lay it on top and use chalk to mark the general area of where you will be cutting. You'll need to cut holes for: Air vents, seat mounts, seat belt mounts, as well as the shifter. I think its a better idea to cut the holes AFTER you line up the carpet INSIDE the car. Also, it's smart to hang onto the pieces you cut off - more on that later.
*As you can see near the right rear passenger side carpet, there was some 'burn' marks from when I first bought the car, it's been bothering me since! 14 year old carpet!!
For holes, I found it better to use a sharp box cutter to punch a slit, rather than cut a perfect hole- it's neater and heck of a lot easier.
Trimming, you'll need to cut about 2-3" on the sides in order to get the carpet tucked under the door sills. BE CAREFULL not to cut more than you have to, because there is NO turning back. Take your time, this is the part where you don't want to rush things. I spent alot of time getting the holes perfect. I only goofed a little near the center under the armrest, but the extra carpet under and it isn't noticeable.
I also found it to be a GOOD time to redo my wiring for my amps. Instead of routing all the wires along the door sills, I went straight down the middle from the radio to the trunk under the carpet. This is so much neater and creates less clutter on the edges.
