Will i be ok with this amp?

I will be doing the big 3 but other than that my electrical system is stock (130a alt)

i bought a hk4000d from a forum member.... i shouldnt have any problems running it at 2 ohms if i set my gain to 1000 rms with a multimeter will i? (yes i know this amp is capable of a lot more but i got it for a good price and i doubt ill ever want to upgrade...)

Might still get some dimming even at 1kw. Those amps are really current hungry and I would at least get a second battery.
