resistance

if you have a two-channel amp that when bridged puts out 800 watts at 4 ohms, is it possible for the amp to put out 1600 watts then at two ohms?

also, is it possible to only wire one of the voice coils on a dual voice coil sub without the sub blowing? dont make fun of me b/c im retarded

you have to run both voice coils of the sub and technically yes, your amp would produce said power but you have to make sure that it will be stable at that ohm load. good luck
