I'm trying to wire a 2-amp system and need help judging the required wire gauges.
The first amp is a Rockford 300S which will be powering my front speakers, the second is a Rockford 700S which will be powering my subs.
What I have so far is this:
2 Gauge wire for the battery to the distro-block and to ground the battery
4 Gauge wire for the distro-block to the 700S and 300S (I know that 8 ga. works for 300 watts, but I haven't found any distro-block that has a 4 and 8 gauge output).
The problem is that I need a 50 amp external fuse for the 700S, but the 300S has an internal fuse. Should I still get a 50 amp fuse or would the presence of a second amp on the circuit require a larger fuse?
Also, what gauge speaker wire should I get for this setup?
