Set up on 3 12's

[spuninsocal 10+ year member]

I am helping a friend pick out a system for his new Dodge Magnum wagon. Its a burl ass car and he wants it to bump hard. We were discussing sub configurations and he says he wants 3 12's. He is already sold on RF Punch stage 3's and those take about 500 watts RMS for sure. So hes lookin at like 1500 watts RMS, from a monoblock sub amp. Now my question is what happens to independence load when 3 12" subs are powered by one mono amp??? Doesnt independence change with every additional sub? if 2 4ohm subs make a 2 ohm load, what is the ohm load when wired with 3 4 ohm subs??? And im also interested in the Tsunami 1800watt class T amps if anyone knows about them. Or any other Amp reccomendations for this set up.
