1967 Barracuda alternator upgrade question

Thanks to Mattax and GMachineDartGT.

I figured pretty much what you said above, that the Alt. would only put out so much (demand) but worried about maxing the gauge out of there was a problem. Like a bad regulator stuck in the charge circuit. I have one of those! LMAO! Seeing the Amp gauge peg at idle is an eye popper!

I am going to be installing an upgraded stereo with an amplifier. The future may hold more.
