I couldn't be more happy with the Focal speakers I put in my car. Here's a set of 6x9s from Crutchfield

Crutchfield rocks. They have helped me out quite a bit in the past when my install doesn't got quite to plan. Those Focal's look pretty nice. Directional tweeter adjustment is nice for the location in the door our speakers are.
Question, what is the difference between 2 way speakers and 4 way speakers. Also which ones are better?
Two-way and 4-way speakers describe how many channels the speakers have internally. So, if you have a 2-way speaker, this is usually a woofer and a tweeter. The speaker has circuitry to make low tones go to the woofer and high tones go to the tweeter. 4-way speakers are the same concept, but with 4 channels the audio is split into. You might assume that this means the sound quality is better, because there are more drivers to specialize on certain frequencies, however I have found that 4-way speakers are usually just crammed together. You'll notice when you start researching that most high quality speakers (JL, Focal, Kicker, Infinity, Polk, Alpine, etc.) don't typically offer 4-way options. If you think about it, it makes sense, as that is a lot of speaker to cram into the same place. These are all "coaxial" speakers. Typically look for a speaker with a good RMS range (max power does not matter). This RMS power is was the speaker needs to run. Couple that with a high sensitivity (over 91 db) and you're looking at a good performing speaker.
A step above these are "component speakers". These are speakers with a separate woofer and tweeter (I.E. the tweeter is
not in the center of the speaker the like the Focal's linked above). These have an external crossover to handle frequency splitting (and you can tune them yourself). More wiring though, and you have to find a place to mount the external tweeter if your car doesn't currently have one (like the CX-9 doesn't, but it does have a great place where the trim panel covers the mirror connection). Powering these could be an issue as well, not sure what the Bose amp is rated for (probably garbage)
Here's some other opinions from another thread on here:

Ok, after visiting several local stores Sat I realize they're way overpriced for speakers not nearly as good. So I'll just online order 2 pair of Kappas. Do those of you that have done this mod recommend getting the foam/poly blankets that go around them and help with reverberation?
Dynamat can always help, as it isolates that vibration from the speaker mount and the metal door frame. On our CX-9's i'm not sure how much it will help, but usually it can't hurt if you throw some behind it and as a sort of gasket where you mount it. You could run into clearance issues this way though, but I say it's worth it if you spend the money on some good speakers like you did.
As for doing the process, I got this youtube link:

from another thread on the forum which details window motor replacement. But the first part shows you how to get to the speaker (as the motor is behind it), and takes you through step-by-step. If you don't already have some trim removal tools, pick some up! They are great and I used them constantly on projects where you don't want to mark anything but need to pry something open.
