Really a 75 amp alternator? I can't even recall seeing one. I do work on cars for a living.
try even mocking up a crappy 1 cube sealed single box. You'll get the punchy snappy bass for rock/metal (Slayer FTW). A ported box is better for the deeper longer make you feel like vomiting bass.
According to one site you amp requires a 30 amp fuse. so you should probably think about a better alternator. Or a small class D amp.

my bad it is a 90 amp.. sorry for the confusion.
