100 amp charging source vs 2 grp31 AGM
My friend plans on running an obscene stereo in his new box on wheels acquisition. He wanted a dedicated power source for it able to power it for a respectable amount of time from battery power alo...

Ain't tinnitus fun?
I did a considerable amount of R&D for "Northwest Regularor" back in the early 90"s. I learned just how nuts stereo competition got 24-years ago. Some of the rigs had new-on-the-market Lifelines. Like six of them in the trunk. My job was to develop fittable alternators with custom wound rotors and stators. At the time I worked with the smaller frame 3-G Ford and managed to improve amperage at 1,600 rotor RPM by 32-amps and total hot amperage to 142. For small Nissans, and Hondas. Couldn't stuff a larger frame alt in there with a jackhammer and shoehorn.
The ND hairpin 270-ampere alternator would be my favorite today. But not with it's original voltage regulator. Absolutely those regs for the 200-ampere and 270-ampere hairpins are junk. The control voltage settings are ALL wrong for absorbed glass mat. Especially when subjecting the batteries to long periods of charging. Driving.
I would gut the OEM regulator and fit a B Circuit regulator. AMPLE POWER makes a programmable alternator voltage regulator that has a field driver NPN mosfet that can endure thehigh field currents of the Hairpin alternators. The AMPLE POWER regs have thermistor temperature compensation. I know David Snead the owner of Ample Power and he knows his stuff. A 270-amp Hairpin coupled to an Ample Power regulator is a setup that stays with the owner and not the rig. The hairpins have big bearings and long brushes - which I like. But I much prefer the 270 over the 200 for low rotor speed work. The reg can be adjusted for flooded, lithium or AGM voltage curves.
Hope this helps
