i was attempting the big-3 upgrade and my positive batt to postitive alt didnt work out well. the anl fuse i used (100amps) blew and caused my battery fuse in the fuse box to blow as well with it. heres some basic info:
-my stereo amp is a 40amp fuse and it is 500rms
-i used 4awg power wire to amp from batt
-my big-3 wires are also 4awg
-i used an ANL type fuse which was rated 100amps
as soon as it happened, i was stuck with the car not starting as the battery fuse was blown. so i ran down to a local kragen and bought a replacement for the fusebox fuse for the battery. which was a 80amp rated fuse (its those cube style kinds with 2 ends that have holes for bolts to hold them down)
so my stereo amp uses a 40amp fuse, my battery fuse from the fuse box is a 80amp, and im using 4awg everywhere... should i try downgrading to a 80amp ANL fuse instead of 100? or should i be going higher?
(another '?': would doing the neg to chassis AND engine to chassis help my electrical system alone without the alt to batt?... any benefit?)
