So looking for some info about amplifier and efficiency. 

 

I have a xcon dual 1ohm 10"  so i can run at either .5ohm or 2ohm What i would like to know is  1500w @ .5ohm or 1500w @ 2ohm the 2ohm amplifier would be drawing more power to make its wattage because of the higher resistance correct ?

No point in running at 0.5 ohms.

X2...@ 2ohms would be more efficient unless i am missing something..

im currently running a 1000.1d amp at .5 ohm so probably pushing 1300 or so. So your telling me if i get an amp that will push lets say 1300 @ 2ohm its going to draw less current ?  

 

2 ohm load would be higher resistance in my understanding require more current to produce same wattage hence the reason my amp that draws x amount of current can only produce 400watts at 4ohm vs  1300 at .5  

 

Im assuming im overlooking something and just trying to get a better understanding as to what because at 4ohm i had no issues with electrical but now that im at .5 i had to do some upgrades. shouldn't that amp have the same power consumption? obviously not but why. 

The amp becomes less efficient the lower you wire down.

so you arent getting 1300 watts or so as you assume, wiring below 1 ohms causes wasted heat and kills amps components quicker.
