Hello all.I am in the process of snagging an ampeg PR-410 Hlf cabinet.It is rated program 1200 watts and RMS handling 600 watts @ 4 ohms.I need to get a power head next.Do I need a head with the same output? is less OK? I was thinking about the SVTpro 3 head rated at RMS 450 @ 4 ohms.Would that be a good match? Or do I need a bigger head? I,m a bit confused, any opinions are welcome.Thanks!
