My Kicker MX700.5 amp's manual says "Fuse90A" and "PowerGroundWire 4GA"
However, when I use this calculator, and follow the "no more than 3% voltage drop" recommendation, 4 gauge wire is apparently only good for up to 8 feet long.
Not too good, but worse, when I calculate the wire size needed for my 34-foot round-trip battery-to-amp-to-battery circuit, I'd need at least 4/0 wire ...
... am I doing this right??
