Advice for Mopar adjustable voltage regulator selection

They're only adjustable within a small range. I don't care how big/many the alternators are, 14.4-ish volts is it. If you start going much over that on a 12v system things start melting. If you need more amps to run a stereo that'll make you deaf anyway, then get a larger capacity battery, or duals. Or just get earbuds and crank it up as loud as you want right from your Iphone, unless you insist on vibrating your car apart.
