are you sure you know what you want? it doesn't matter if a amp is 1ohm stable or not, it will still run in 2 ohm. I'm running my setup at 2ohm too, but my amp is 1 ohm stable. I ran a system at 4ohm load but had a amp that was stable at 2ohm(before it all was stolen). I'd say probably 90% of amps say they are 1ohm stable. Doesn't mean you have to run it at that. We can read, you are just being difficult. it's not a waste to have extra power, it's less strain on the amp, less heat, and better efficiency I would think.
Good luck, the kicker zx1000.1 looks nice.
