Hard to say. The 400 in the name probably refers to it’s power rating but without knowing what the measurement system is you can’t convert.
The web site below for the 400+ (if that’s your amp) says it gives 500 watts of “transient power peaks”. This usually means they are measuring instantaneous power which is much migher than RMS power.
You could send them an e-mail and see what they say.
Sorry I couldn’t be more help. Maybe somebody else will have more information.
