After much research, I decided to go with Polk GXR69 3-way 6x9's in the rear cargo area. Last evening, I installed them without any problem and the speakers fit just fine. I consider them as EZ-fit though the crutchfield said it will not fit. These are availble at crutchfield for $59.99 plus 5.99 shipping.
Now the goal for next week is to purchase / install Pioneer TS-A1767 in the front doors. The thing is crutchfiled is selling them for $120 when some others are selling for only $60. Anyways, I just wanted to provided an update for choice limited rear 6x9's.
