Amp Wiring/fuse question Options

[djrob90]

Right, I’ve got 4 amps, 4 10” subs and 2 powercaps. The intention is to run the amps off of a FUSED distribution block (1 into 4) and another distribution block for the caps (1 into 2) My old setup of 2 amps required a 30amp fuse and 40amp fuse on the block and there was a 70amp fuse on the main 4 gauge cable really close to the battery. My question is that now, aside from these 2 amps, I’ve got a further 2 amps that require a 40amp fuse and a 60amp fuse, this takes the total amps upto 170 and will obviously blow the 70amp fuse in the main cable. I’ve never seen any AGU fuses rated this high and I was wondering, am I being overkill with the fuse in the battery splice (as everything else is individually fused) or should I not be pulling this sort of amperage from one piece of 4 gauge and should I run another piece instead?

4ga is good for up to about 150 amps. so running another piece of 4ga is an option. or you could run 2ga and split it to all four amps. agu fuses do not come that large you will need to use an anl fuse or get a circuit breaker. remember the breaker by the battery is there to protect the wire. if you get into a wreck and the wire gets cut and it isn't fused you will start a fire. it is not optional.

also if you are using quality amplifiers that are actually pulling 170 amps you are gonna put a hurting on your alternator. stock is only 70 amps output. you may want to upgrade.
