stock alt generates 110 Amps at some unknown engine speed.

Thats 1584 watts at the output terminal of your alternator... So tell me how you plan to magically make up the rest of the power, and get it to the amp?

None of the things you mentioned will help you.

Just do the "big three" and get a HO alternator already. You dont need special batteries or a cap unless your amp sucks.
