ralittle2....Your problem is based on your main amplifier,this amp is much more sensitive than the Outlaws own amplifiers it is not that is any more powerful or that it is better,but is just on the sensitivity of the design;just like your speakers,some are more sensitive then others.But if you can calibrate your system to be in balance why does it matter?The problem could arise if you couldn't adjust your surrounds to the same level as your fronts,you did not state that in your question so i couln't comment on that,but i hope i have help with your question.(The same is true with gonk's system same speakers,but different levels.It's all in the sensitivity of the amplifier.)
