OK, i just finished installing the other speaker and it sounds way better now, even with the stock stereo playing an MP3 from a CD, then from an iPod using the Aux IN in the glove compartment. I recommend doing this, the stock speakers sound really crappy and have muffed sound.
I chose 3-way speakers since I did the same to my previous car and they sound great. I'm thinking about adding two new speaker to the back doors but on the meanwhile I will enjoy these two.
Step 1: Remove small tweeter panel. There are no screws for this one, it's only clipped on.
Step 2: Remove door handle screw (Torx 25)
Step 3: Remove door deflector and screw, also Torx 25.
Step 4: Remove small side panel and screw, also Torx 25.
Step 5: Remove arm rest modling, it's only clipped.
Step 6: Remove arm rest controls housing and unclip the harnesses
Step 7: Remove both arm screws behind the controls housing from the arm rest.
Step 8: Remove panel, it has about 7 clips so be careful.
Step 9: Now you can see the stock speaker. Remove the 3 screws holding the speaker together and unclip the top connector. Now remove the speaker.
Step 10: This is the backside of the speaker. As you can see the speaker is part of a housing itself. We will have to completely remove the cardboard, wires, coil and magnet in order to use the housing as bracket.
Step 11: This is the stock speaker with the cardboard and wires removed from the bracket. on the inside you will see the coil and its base.
Step 12: Same case, only now you can see the inner coil.
Step 13: Since the speakers i bought had a very large magnet I had to remove the section that was holding the magnet from the stock speaker. Since I don't own any kind of saw i used my soldering iron to melt the plastic off.
Step 14: From left to right. Coil/cardboard, bracket, magnet.
Step 15: You will only be using the bracket and will only be using the outer rim so you can also remove the supports from the inside, i left them there so I wouldn't make a mess with the melting.
Step 16: This is a picture of the speaker already drilled into the bracket, you will notice 4 screws i used to drill directly into the bracket. Don't worry, the speaker will be very firm and won't get loose.
Step 17: New speaker almost ready, i used the wires that came with it and cut it up so the wires weren't that long.
Step 18: New speaker soldered onto the bracket contacts, this is necessary since the contacts are part of the bracket. The good thing about doing it this way is that you don't have to cut up the original wires that come from the door.
ALL DONE !!! You can see the mid-range and tweeter housing from inside the door panel after I put it all together again.
