good, thanks.

i read somewhere that an amp has the same current draw no matter what you wire it to...

not true. when the ohm load changes the efficiency of your amp changes. ultimately you have to multiply efficiency in to find current draw :-)

Actually the efficiency will go up because he will have adequate charging system for the 1/2 load. Most class D's run close if not higher than 80% and at a reduced load it can only get higher. Polo..

In all actuality a full load is 4 ohms a short is opposite of a load at 0 ohms. An amplifiers efficiency is the highest at 4ohms and above, begins to fall the closer you bring it to 0 ohms. If your amp is rated at 2 ohm stability and you wire it at 4 ohm the efficieny will be higher because there will be less power wasted on heat. This is why your amplifier makes more heat with less a load. Polo...
