(power) What do I need????

[502CEC 10+ year member]

I have 2 2400 and 1 750 so about 5500w all together. I have done the big 3 and I have a 275a alt. with a Duramax gold under the hood and 1 yellow top in the back. When I turn it up at comps my volts go down to the high 11's. What should I do to keep me @ 14v or atleast in the high 13's on my volt meter?

3 or 4 big group 31 batts should help might need more depending on how long you want it to stay at that voltage

The amps are brutus amps and I know they r not pushing a true 2400 a piece but I need everything ready for when I can upgrade amps. And what are you talking about by checking the grounds? And how do I go about that?

Also these readings on my meter are with my car running and wedged at 2k rpm. Should I look into getting ahold of Ohio Generators to see if they cam make the alt put out more at 2k rpm.? Or will more batteries be the only thing to help?
