For my past sound systems in my cars I've jus used the fuses that were supplied with the amp kit. For his system I'm buying 40 feet of 0 gauge wire todo a big 3 upgrade and to run to the Kinetik HC1800 battery in the back to run my JBL GTO14001 (2000w mono amplifier with 1500 RMS @. 2 ohms) I wanna put 2 fuses on the cable connecting the 2 batteries as a safety precaution. What size fuses should I use for this and where could I find this fuse? I already have a 4 gauge monster cable wiring kit for my amp off the kinetik battery. Only need fuses for the battery to battery wiring.
