Alright, I'm look at power amps right now to go with a SVP-PRO. I need something to run at 4ohms bridged. The cab its going to be pushing for right now is a SVT-410HLF. So having enough wattage won't be an issue with either of these. My main concern is heat from bridging at 4ohms. The 1850HD is supposed to do a better job at this but is the RMX1450 good enough? I really don't want my power amp to shut off in the middle of a gig because its overheating. At first, I was thinking about a Behringer EP1500 but I don't think I could get over the guilt of buying such a blatant copy of the RMX series. I appreciate your help.
