Im going to be running 4 of the new Cadence IA9 HC and Im going to be getting 2 of the upcoming goup 27 batteries from powermaster in the fall along with a D3400 up front and 1 D1200 and 1 D680 in the back and according to powermaster new website on the amount of power each battery can handle the 2 2700 should be able to handle 4000 watts rms a piece as back ups and then the 1200 is 2000 rms I think and the 680 is 1000 rms and the 3400 since its up front should be 2000 watts rms as well and then I have all this on a 250 amp alt from mechman my question is am I figuring this right and will the 4 IA9hc which put out 2400 rms a piece be ok or will I have to be careful I plan on keeping the gians down if I have to except for burps of course and Im basically needing to know if I will have to keep the gains down costantly or if I will be ok to keep them up

use the volume knob carefully watch your voltage and you should be ok. make sure its a digital voltmeter analogs dont work as fast to show some of the quick dips.
