1 amp, single 1000ca everstart maxx, factory alt
4 ohm nominal = 518 watts @ 88% efficiency (voltage fell from 14.3v, to 14.0v)
2 ohm nominal = 948 watts @ 85% efficiency (voltage fell from 14.3v, to 13.6v)
1 ohm nominal = 1510 watts @ 78% efficiency (voltage fell from 14.3v, to 12.4 volts
.5 ohm nominal = 1615 watts @ 72% efficiency (voltage fell from 14.3v, to 11.8v)
.35 ohm nominal = 1748 watts @ 67% efficiency (voltage fell from 14.3v, to 11.4v)
test results from sundown.. since 948 watts won't cut it for the bl, i have to go with 0.5 ohm correct?
