YOU COULD ALWAYS REPLACE THE TWO GANG OUTLET SUPPLYING THE 'SOURCES', WITH A FOUR GANG... USE THE ADDITIONAL TWO OUTLETS FOR THE POWER COND AND THE EXSISTING TWO GANG DRIVING THE POWER AMP TO RUN BOTH AMPS... Personally, if at all possible, I'd add another line... depending on the amount of current the projected second amp will draw...
My amp uses two cords... I've run it on two separate dedicated lines, and on just one 20a dedicated line..(I've got four) ... If there is indeed a difference, I can't hear it. Currently I'm down to using just three lines, all 20's, one for CD, one for preamp & some sources, and one for the amp. This seems both conveinent and best sounding on the whole. the amp is set to the line closest to the entry of the bus. Which ever way you choose, regarding the amp, keep both amps on the same phase. Can be different lines but ensure use of the same phase when using two amps.
