how to run 3 batteries? (1 under the hood 2 in the back)

[@Dappster360]

Hey fellow car audio people,I already have a stinger SPV44 660 amp battery and I'll be buying another one soon but I have no clue on how to wire the 2 together. I'll basically be running my normal battery under the hood and these 2 in the back. Obviously I'm just getting into the bigger systems so,any help on this would be awesome! (current system is 2 massive audio hippo 8s + massive audio N3 amp ) (COMING SOON system will be 4 hippo 8s + 2x massive audio N3 amps )

n3 amp RMS 1400watt

Hippo 8" 500 watts RMS

thanks for the help trying to get this set up before November for import face off.

Run them in parallel and make sure to fuse in the front and back

check the float voltages of all 3 fully charged but unwired just in case before you put them together. you're running the same battery so it should be simple just make sure you fuse like adulbrich said.

if it turns out your current battery is low id go with a different brand just for cost savings without diminishing quality

Wow thanks so much for the info! yeah I planned on running in parallel it looked like it would combine the batteries voltage and make basically a bigger battery.

It doesn't "combine voltage".

It's still 12v, but there is more capacity (amp hours)
