Hello Everyone -
Well, this weekend I tackled the rear speaker installation. Let me just say WOW! It is quite an upgrade compared to how flat the stereo sounded with solely the stock speakers in the dash. The sound is much more 3D and is just awesome. I used the OEM kit which was fantastic. I would say difficulty is about a 7/10. Only took about 3 hours or so and was well worth-it. As others have already agreed, this mod is highly reccomended!

... let me know if you have any questions.
Here are the speakers going into the storage compartment:
And the finished product:
