@Roky - I went back and checked the polarity and it is correct in my Jeep. The Metra adapter's white wire is positive (I tripled checked this with a fluke meter) and according to the Infinity instructions, the wide blade on the speaker is the positive connection and the white wire in the Metra adapter has the wide blade--so it is correct in my case. Note that I have the 8.4" screen with the OEM Alpine "upgraded" system (amp + sub). The Infinity's come with a small roll of foam gasket material and I applied it to the perimeter of both speakers on the back side (the circle that you can see in the image below).
Here is a photo (pre-trim) to give you an idea of what has to be snipped so that it will fit. I intentionally snugged them into place so the hold down screws would make a mark on the hold down tab so that I could see what needed to be trimmed. Note the OEM speaker grills are no where near the speakers, you have to press down on them quite a bit before it contacts the tweeter. Last, but not least, the speaker surrounds are totally free to move without restriction or contacting anything. Hope this helps!
