Gold Member Username: GlasswolfNorthWest, Michigan USA Post Number: 1543 Registered: Dec-03 | Phoenix Gold amps, at the higher end, are "high current" amps and designed to run abnormally low impedances. as I said *most* amps won't do that. Orion's 225HCCA was stable to half an Ohm as well. Those aren't your average amplifier though. Most people wouldn't pay $600 for an amp rated for 25 watts RMS x 2 @ 4 Ohms.
