I still don't understand ohms and watts and I'm not asking anyone to explain it to me. I want an amp setup that will suit my needs and allow me to get loud enough with overhead. Would an Ampeg svp-pro head (or svp-bsp, if it's the same type thing) running through a QSC RMX1450 power amp and into an Ampeg BSE410HLF work? The RMX1450 runs 450W @ 4 ohms and the Ampeg cab can handle 400W RMS. Will I need to get a different cab? If so what kind and where can I find one aroundt the same price as the BSE410HLF? Any help would be appreciated. Thanks.
