I do understand all that, the power ratings at different speaker impedances would be quoted in the amp specs anyway.

My question all along has simply been what figure do the rigs generaly quote?

I wasnt sure if amp manf quote rms or peak (although I now think its rms)

and also wether the rigs quote the total power they have or the actual level they run at.

or just the highest figure they can get away with as there must be a bit of "whose got the most powerful rig" competition ?
