I have 3 amps, all kicker. ZX750.1, ZX200.2, ZX 200.4. I will have the + wire to a dist box from the battery. The wire is 1/0g from batt to dist box then 4g to amps and ground. What size fuse do I need for the batt to dist box wire? The ZX750.1 was installed prof. It already has 100a fuse on 1/0g or 2g wire. (havent looked to close yet, but i think its 1/0g) I jus need to upgrade fuse size bcuz I now hav 2 more kicker amps. BTW 750.1 is for subs and other amps for speakers and tweeter horns.

PS- I was told to add the fuse sizes from amps together and that should b around the size i need. let me kno if this is true. thks
