Current Consumption at 120V (in amperes) at typical/full/maximum output power (idle current= 1 amp)
RMX 4050HD RMX 5050
8 ohms typical= 6.4, full= 12.5, maximum= 25.5 typical= 8.7, full= 17.0, maximum= 34.4
4 ohms typical= 10.0, full= 20.1, maximum= 42.2 typical= 13.9, full= 26.9, maximum= 56.4
2 ohms typical= 14.5, full= 30.6, maximum= 65.7 typical= 18.9, full= 38.0, maximum= 84.7
