I am planning out my install and want to run a single power cable from the battery to the trunk, then split into two 4 gauge cables to power a sub amp and a speaker amp. Each are rated for 4 gauge power. My thought is to use a larger fuse at the battery and then 2 individual fuses at the split in the trunk, with each fuse being rated for its individual amp. Any thoughts or experience on this setup? My main hangup is that I'm not sure what gauge cable would be good for the run from the battery or if I should just play it safe and go with 0 gauge.
