Look up Ohms law calculator. As long as you have 2 of 4 variables it will get you the info you need.

You may want to use the tested wattage of that amp in your formula.

The Kappa 62.11i max wattage is 225 and rms is 90 watts.
I would not set the amp to max specs as the Kappas will not take the power for to long.
To be on the safe side I would suggest no more than 20vac which is 200watts for the Kappas and no more than 24 vac which is 150 watts for the kickers.
