proper electrical for saz3000?

[302yota 10+ year member]

im currently running the stock (5 year old) factory batt up front, 130a alt, and a kinetic hc2000 ( I bought it used, and im sure its pretty old also) in the back...all 1/0 wire, including the big 3...amp Is probably turned halfway up at 1.4 ohms on a fi sp4 18...my voltage drops as low as 11.5 volts at idle...what would be a good battery setup to be able to get the most power out of my amp? I was thinking a hc2000 under the hood and buying a new hc2000 for the rear and doing away with both batts that I have now

Your alt and batts are not enough to keep up. If you want to keep that alt i would look for a pair of Group 31 Agm's and probably a better battery to go under the hood, preferably a smaller Agm battery. That would help some. Kinetic batterys are really not as good as they are advertised to be.

Get a d3400 or one of those eaton batts from jefff look in the electrical classifieds. See how that does for u

If that voltage stays that low you're going to fry that amp....

I don't know why people insist on playing things full bore at idle anyway. It's obnoxious and much harder on the electrical system to boot.

well I usually like to keep it around 2k rpms when demoing, but I still have bad voltage drop then...by a "group 31" battery do yall mean like a 3100...and whats the difference between agm and non agm batts?
