Cross talk happens when you run stereo. It is the over/under lap between the left and right channels. Like a sound that moves from one side to the other. This should not be an issue because the head unit should run the rear channels as a mono signal once the subwoofer setting in the radio is active. I know for a fact that the Pioneers produce a mono signal so there is good reason to believe that the Sony should as well. Pioneer has had the ability to do sub on their rear speaker outputs for years, on their better radios.
DVC is shorthand for Dual Voice Coil. Or Disney Vacation Club, but I am pretty confident is was the former.
Damping factor is the ability of the power source to stop and start the speaker, the ability to effectively control the cone movement. Since we are going there, lets talk a little more about it. Yes it is likely that the radio does not have a stellar damping factor. This becomes a larger issue the larger and heavier the cone gets. The more power that is required to run the speaker, the more the damping factor requirement also increases. The damping factor is the brakes of the speaker. The higher the damping factor the more accurate and musical the speaker will perform.
I am pretty confident that the 8 inch will be pretty accurate with the small amount of power produced by the radio, it is fairly sensitive(light weight cone, sufficient motor structure, and a tuned vented enclosure) and also plenty capable of being accurate enough to be very enjoyable.
Yes the better option would be to add an amp for both the sub and the front speakers but within the constraints of the OP you have picked a solid value engineered little system. Don't get too bogged down in the way other folks would accomplish similar tasks. Go for it. You will be happy with this little setup. If you find that it is lacking in one area or another, you will not have to go backward to upgrade. It would only be a matter of adding an amplifier to the existing build to get better quality out of the chosen parts.
