I was just kinda curious on how to lower impedance on class D amplifiers. I would like to know how to lower the output impedance. The load I'd like to put onto it is 1hm: and the amplifier is only 2hm: capable. Any info or links on how to accomplish this would be nice.

As with any other amplifier, simply double the output devices (bearing in mind correct current sharing and drive requirements), you will also need to double the power supply capability. For class D you may well have to uprate the output filtering as well.
No, class D amps, like most others, can feed their minimum load and upwards quite happily. I've never used my class D amp in to 4 ohms (400W+400W), only ever used 8 ohms on it (200W+200W) - like all such amps the specs even list it.
