i bought a pg tantrum 1200.1 thinking it was 1200 watts rms @ 2ohms but the birth sheet say 1494 @ 2ohms. i want it to run an idmax 12 which is only rated at 1000. i figured if i kept my gains down 1200 would be all right but i'm not sure if 1500 will be. it is also rated at like 14.5 volts or something like that. i have a 200 amp alt. i will install but will i be constantly running at that high of volts?
