I thought budget switch mode amps can only deliver bursts of their rated power and can't deliver it continuous if they needed to. Also from what I know more expensive touring switch mode amps CAN deliver continuous power because they have bigger built in power supplies. When I mentioned the RMX2450 I meant that from my experience and also the experience of a lot of people i've talked to, newer amplifiers like the RMX2450, Crown XTI4000, Crown XLS2500 etc..the older toroidal amps like the QSC EX2500, MX3000A, Crest CA9 etc...are better becauser they're able to pull the power needed from the mains supply plus i've heard people say the older amps had bigger capacitors or more capacitors to store more electrical power for when subs need it, wheras newer budget range switch mode amps seem to quickly run out of stored power.
