MPS question??

[kg1961]

I have both the mps2240 and mps2220
looking in the manual sec here on the forum
the 2240 has bridged rating to 1ohm the 2220 only has 4ohm ?
if the 2240 makes 125x1 4,185 2 and 300x1 1 ohm than how much power will the 2220 make in 2ohm or 1?
anyone ever tested them? are the rating close?
thanks again
