infinity kappa midrange freezing in cold

I have had Infinity Kappa 6.5 components in my front doors for about 3 years. I used to live in Atlanta though, so this is my first really cold winter (moved to NY). My front left midrange has been freezing in this last week or two of 20 degree weather.   After about 20 minutes of the heat on in my car it will thaw out enough to sound crackly - and then after a few more minutes it fully thaws out and sounds perfect. I removed the speaker and inspected it, and it appears fine and there was no visible ice on the unit or any ice inside my door. Thus, I believe it is the aluminum heatsink clamping down on the voice coil or something to that effect. I find it odd that only one of the two is doing it though.

Was there a plastic baffle behind the OEM speaker that got removed for the install?  The manufacturer knows water gets into the door, so they generally channel the water away from the speakers and electronics mounted inside the door.  The speaker should not be getting wet.  If you mounted it, and it is not in the traditional spot for a speaker, you may have to install a baffle or some kind of moisture barrier behind the speaker to keep it from getting wet. 

i did remove the baffle to install the speaker(my doors are very shallow)...but it freezes even when it is dry.

there is still moisture in the air that gets into the speaker

I fully understand that - but short of installing it in an airtight enclosure there is noway to prevent ambient moisture from getting into the speaker. My point was that my doors are not leaking onto the back of the driver so it is not actually an ice buildup. Frost from ambient moisture maybe, but not ice. Also - if it were the ambient moisture as the sole problem I would think both drivers would freeze. The moisture content of the air isnt going to vary much from one side of my car to the other.

 could be the ferrofluid if used in the speaker freezing....Ive heard of that before.

Ferrofluid is only used in tweeters - it is my midrange that is freezing.

Swap the left and right speakers.  If the problem remains in the same door, replace or get a new baffle to keep the freezing speaker dry. 

"Ferrofluid is only used in tweeters." Sorry, this isn't true.
