I know what the difference between rms and max, but for the opti2000d what does it say 1600W rms power @ 1.3ohms, but 2000w max power @ 0.5 ohms?
* 700 Watts RMS Power @ 4 Ohms
* 1100 Watts RMS Power @ 2 Ohms
* 1600 Watts RMS Power @ 1.3 Ohms
* 2000 Watts Max Power @ 0.5 Ohms
* 4000 Watts Bridge Max Power @ 2 Ohms
What does it do rms wise @ 0.5 ohms?
