Highest Amp Alternator For a 72 Duster

charger426 said
I'm going to be upping my alternator to a squareback 100 amp style this spring to handle my new stereo and some extra stuff (electric fans, lights, MSD box, ect). I'm going to be doing my wiring per the below link. I figure if it was good enough for factor MaMopar cop/taxi cars it should work now, no sense in reinventing the wheel.

As far as the stereo goes I'm going with 2 12 Dayton Audio subs, and Kicker 6x9 (rear deck), 4x6 or 4" (kick panels), and 3.5 (dash). Sub amp is a Rockford Fostgate T1500-1 and the other speakers will be powered by a Rockford T600-4. Something that will "bandaid a weaker system and help with the big one time bass hits is a capacitor. I'm going to run a 40 farad cap which is overkill (rule of thumb is 1 farad per 1000 RMS watts) but I rather have some extra headroom given how small of an alternator I'm going to be running.

Actually a great idea, keeps the amp gage, but isolates it from the rest of the wiring. Since my dash is sitting on saw horses and I am modifying it, i may go this route. My alternate route was to have a gage shop convert my amp gage to volts, and wiring it up as such, but leave it looking like an amp gage.

If you are running headlamp relays, then straight up halogen sealed beams are actually pretty freakin bright as they are now getting full rated voltage.

I plan on running an electric engine fan, and upgrading to halogen headlights, but going to LED lighting everywhere else. I dont plan on a stereo, my car was a radio delete. I want to keep it this way. I am thinking a 60 amp would be plenty for my application.

hope this helps
