Part 97.307(A): 

  No amateur station transmission shall occupy more bandwidth than 
  necessary for the information rate and emission type being 
  transmitted, in accordance with good amateur practice.

With voice modulation, it has been proven repeatedly that 3 KHz is 
more than adequate to reasonably reproduce the human voice with 
sufficient intelligibility for communications service.  *YOU* do 
not get to determine the "necessary bandwidth."  That is determined 
by good engineering practice.  If choose to use full carrier DSB AM, 
the bandwidth necessary is no more than 6 KHz (+/- 3 KHz).  +/-5 
or +/-6 KHz is being a spectrum hog.
