When I did a search for the Thiel 3.6s it stated its sensitivity rating @ 86dB/W/m (2.8V) which would be within what would be a normal sensitivity rating. Their impendence however does drop off to a low 2.3 ohm and 3 ohm through most of their range. I would suspect this would be a difficult load for any amp.

Does the thermal overload led come on when you play the music loud ? If not I wouldn't be to worried about it but running some sort of fan ( Parasound or not ) would be a good idea imo.
