Danny Ruiz Posted June 27, 2012 Report Share Posted June 27, 2012 i am planning to add another amp so i thought a second battery would help. whats the process of doing this. Quote Link to comment Share on other sites More sharing options...
sprkn_ranger Posted June 27, 2012 Report Share Posted June 27, 2012 (edited) Just run a positive 1/0 wire between the two battery's positive terminals and fuse both ends of the wire close to the batterys. And if you have enough wire, run another 1/0 wire from the neg terminals on each battery. So like this: Batt pos -----fuse-----------------fuse-----batt pos Batt neg --------------------------------------batt neg If you dont have enough wire for the neg run, then just ground both batterys with 1/0 to the chassis or frame.

graham0599 Posted June 27, 2012 Report Share Posted June 27, 2012 (edited) 1. Make sure you have an alt that can power both 2. + from front batt to back batt 3. - from front batt to back batt 4. - from back batt to a good ground Oh ya forget to say fuse the positive on both ends. At least one end Edited June 27, 2012 by graham0599 Quote My 350z build- http://www.stevemeadedesigns.com/board/topic/174424-2008-350z-build/page-2?hl=%2B350z+%2Bbuild#entry2605678 Link to comment Share on other sites More sharing options...
ALPINE408 Posted June 27, 2012 Report Share Posted June 27, 2012 Never seen an alt not be able to power some batts? Care to elaborate on this? I have had 6 batts on a 60 amp stock alt worked just fine just takes longer to charge them Quote Have you ever had your woofers blown? Link to comment Share on other sites More sharing options...

ChrisAllen Posted June 27, 2012 Report Share Posted June 27, 2012 Searching helps a lot. It's soooo easy to do, and you could even search on google. I doubt anyone is going to spoon feed for such an easy subject since there are plenty of write-ups and how-to's of adding another battery properly as well as upgrading your alternator (which you should plan on doing if you plan on pushing a lot of power) Quote Link to comment Share on other sites More sharing options...

At least one end Fusing just one end is totally pointless, if you have a positive wire in between two batteries, and only fuse one end and the wire shorts somewhere, the un-fused battery will burn up the wire and probobly burn your car to the ground. You MUST fuse both ends to protect the wire from overloading in case of a short.
