natemikegray Posted January 19, 2018 Report Share Posted January 19, 2018 Hello. I've been planning out a system that I'm throwing in my Tahoe. Largest system I've built so far. 12,000w to 4 15's. Anyway, I already know that alts and bats are things I am going to need for this build. Now, the alternator thing is easy for me to calculate. 300amp alt is roughly 3000w. But I haven't done any calculating for batteries since most system I install are less than 1000w. There are multiple ratings on a battery. Max amperage, Cranking amps, Cold cranking amps, and Amp hours. What I don't know, and would like to find out, is how do I calculate how many watts I can get out of a battery? Since draw is rated in amp hours I assume Watts rated in hours as well. Thanks for the help. 2001 Tahoe No system. Not even aftermarket headunit.

Skullz Posted January 19, 2018 Report Share Posted January 19, 2018 AGM or Lithium? With AGM you'll want to get roughly 6 batteries in a bank, but more would allow you more capacity to prevent rapid voltage drops. I do not have any experience with Lithium so i really have no idea on what the AH translates to real world capacities. 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...

Kyblack76 Posted January 19, 2018 Report Share Posted January 19, 2018 12k rms? Or 12k total from ratings on the amps? What amps? And what load will you show the amps. Give more info on your gear please. SMD SUPER SELLER The Burban Build Blazer Build sold Acura trunk build sold Link to comment Share on other sites More sharing options...
