It appears the part is failing at start-up. The part is exploding! I don't see any advantage going in series. I think you want to keep the resistance as low as possible. I've shown you only need 0.6 ohm.

A series operation would probably make more sense, as you'd have a better handle on how much current and resistance you'll get, but parallel might have some benefits if you are only looking at start up.
It appears...
Do you have a video of the explosion?
Since any thermistor in this circuit will see the same voltage across while limiting surge current, a larger resistance that has the same thermal time constant will dissipate less energy -> V^2/R
I'm done...
