Kenwood Excelon KAC-X810D reliable/do power?

I have a kenwood KAC-X811D which I think is just a different/newer case on the same amp. Its the same 1600 watts max specs. Some notable points are that a J/L 500/1 was more powerful at 1ohm on Two Type-R 12's and and it gets hot at 1 -ohm when you really push it hard and it shuts off. Eventually a trace fried but it was at a SPL Competition/Show and the guy there fixed it for 5$ in the local shop. It hasnt given me any problems since he re soldered the trace but i havent pushed it as hard at 1 ohm i have it on one Sub now at 2ohms. Oh also we had it on two 15" L7's and it only hit 137 soemthing on the TL but that was with a ton of stock insulation and sound deadening in a sedan trunk. When we removed the insulation and Installed the 2500D its hitting about 149.1 in the kick now. We need an electrical upgrade and a new box though.

 
I have no direct experience with that particular moel amp but I do have experience with some older eXcelon amps (the two amps in my car currently are both eXcelons - one from before they were even labeled eXcelon)

Both of mine do more than rated output according to my personal tests so I would assume that the X810D does as well (not huge amounts over ratings, mind you, but at or above ratings nonetheless) and both of mine have proven reliable as a rock.

On the X810D the output increase going from a 2 Ohm to a 1 Ohm load is actually pretty negligible (100 watts or so) so I would suggest that the 1 Ohm load stability was incorporated more for wiring flexibility than anything else.
