[QUOTE="daforce007, post: 746654, member: 559598"] Hey, y'all. I'm putting in a Phoenix Gold Ti500.4 this week to power the speakers (all 4ohm) in my car and later on this summer, I plan on getting a PG Ti400.2 or a Ti600.2 for a sub (is that a good choice?). Anyways, I want to wire everything so I can just throw in the amp and sub when I get the equipment. Can I run a distribution block using only one output for the time being? and is this how it should be wired for power? •0/1ga from battery, to a fuse or circuit breaker, then to a fused distribution block. •4ga power from the distribution block output to the amps. •4ga ground from each amp to a single grounding point/bolt (my battery is in my trunk, so can I use the same bolt my battery is grounded on?) Should I use a fuse or a circuit breaker? Its been suggested that I use a breaker because of my future upgrades, so how do I go about choosing the circuit breaker? Do you just add up the current requirements? The Ti500.4 amp I'm going to put in now requires a 60A fuse. My amp choices in the future are the: • Ti400.2 - Bridged - requires a 60A fuse • or Ti600.2 - Bridged - requires an 80A fuse So with my amp possible combos: • Ti500.4 (60A) + Ti400.2 (60A) = 120A • or Ti500.4 (60A) + Ti600.2 (80A) = 140A So do I simply find a breaker rated for 140A? or do you have to go by the wiring? I found these two Phoenix Gold circuit breakers: PG VB140 • 140A - use with 2 gauge cable (can i use 1/0 gauge cable instead?) • Rated at 200 - 250% for 5 seconds PG VB200 • 200A - use with 1/0 gauge cable (Do I have to get this since i'm running 0/1 from the batt to the fuse block?) • Rated at 200 - 250% for 5 seconds THANKS! sorry for the long post. if anything is unclear let me know!
