CodyDaGoat Posted February 20, 2019 Report Share Posted February 20, 2019 Wiring 3 XS power batteries in parallel in the trunk of my car. Wiring with 2 runs of OFC 0 gauge, and wanted to ask a question about grounding. I plan on grounding underneath the back seats directly to the cars body. Should I ground each battery separately for a total of, or just one run ground from one battery to the body since they are all wired together? Thanks in advance Link to comment Share on other sites More sharing options...
9Nails Posted February 24, 2019 Report Share Posted February 24, 2019 What's your max amperage for the alternator(s), your wire lengths, and what is the max amperage draw for your amplifiers? Safe to assume that you're charging voltage is between 13.8 - 14.2 V? If your ground is just a few feet away you could get by easily with one 0 gauge, each battery. To be safe, if you have two 0 gauge coming in to the bank, then two 0 gauge going out is typically suggested. Link to comment Share on other sites More sharing options...
Dragonsyph Posted February 24, 2019 Report Share Posted February 24, 2019 If you are running two zero gauge from front to back i Would suggest 2 zero gauge grounds in back to frame at a minimum. Usly you want a 1 to 1 ratio and of = wire gauge. ♦ Sundown NSV4 18" + Sundown SALT-4 Baby ♦ MechMan Elite 370a + XS3100 - XP3000 ♦ SHCA 1/0 OFC(blue) + SMD Fuse Holders(blue) ♦ Pioneer AVH-2440NEX + SHCA Pro RCA Link to comment Share on other sites More sharing options...
