hi frank, mrtry is right,you wont have any problem at all with either amp from a 15 amp line,in my bedroom rig im running a pair of 300 watt monoblocks & a single 200 watt monoblock plus a preamp & a dvd/cd player all from a 15 amp line with no problem at all.
even in my big rig where im running 1,530 watts of amplification i did not need to put in a 20 amp line until my wife decided to use the same circut to use her damn clothes iron on while im listening
as a side note after i installed 2 seperate 20 amp lines for my main rig there was no sonic improvement at all,the rig sounded the same,both amps your looking at have sufficient power reserves to drive 200 watts continuously without tripping a breaker.
