If I'm getting a subwoofer that is 1.4 ohms dvc and when I wire it for .7 ohms, what's the formula for calculating the wattage produced by and amplifier that is stable at 1 ohm? Like how much would a saz 1500 produce at .7 ohms?
Also would a stock alt but with big 3 and a batt be enough to power this or should I add another one?
Lastly does the gain setting limit the total wattage produced? Like is setting the gain 50% equal to limiting a 3000 watt amp to only 1500 watts? I'm asking because I want to know how I could limit the total output if I don't feel my car's electricals can currently handle the full power.
