How much power can you use before you are going to need a high output alt? As is how big of an amp can you use with just stock electrical.

depends on your stock alternator, if you have done the big 3 mod, what kind of battery bank you have, etc etc

For some perspective, i ran about 2500RMS on a stock 130 amp alternator and a kinetik 2400, and voltage would drop into the low 12's/high 11's at idle

Hemi, 4.7, or the V6? Towing package, sport package or anything like that?

Well I would say your alt is at least over 105amp so i would thing with the truck stock you could a little over 2k watts.
