Remember that the max current handling that is quoted for the unit is only if you ran your amps at full. now, a pair of 601 running at 600+ watts has to be unbearable IMO.
I have
three MC601 and one MC205 all connected to one P10.
I use two P5's where I plug all of my sources/front end components.
Right now I am watching basketball at 6.0W (wife is cooking and the hood is on
) and the load registers 27% on the P10
GO FOR IT!
