How big of an alternator do I need?

[JLAW2058]

I'm gonna be running just under 3000 watts with (2) XS power d3400 power cells. I have a 220a alternator but im not sure if that will be enough. What do you think?

I think that will be plenty. Did you also do the big three?

Should be fine if ran 1ohm or up if you run .5 ohm you might want more battery or go bigger with alt

I'm gonna be running my sundown audio zv4 15 @ 2ohm, 2000w and another 400w rms 4-channel amp for my (4) 6x9s.

Depends on amp but sounds fine. Class d amp rated to make power at 2 will be fine class a/b or two channel bridged might need more batts

You should be all set can't guarantee it so watch your voltage

If you have your big 3 done your good, just monitor your voltage.
