So I am in the midst of stereo upgrade extravaganza and am starting to wonder if my alternator will keep up. 2001 MoobiusV, Indmar Assault, black alternator so I'm guessing it's the 55A. I'm going to be running a Kicker 750.1 mono to power the sub, Kicker 350.4 for the cabin speakers, and 350.2 to power the tower speakers.

I already have dual batteries with a nice HD secondary battery. I'm a little worried if my alternator will keep up. If I should plan to upgrade alternators or install a capacitor (which I've heard very mixed reviews about)?

Will post some stereo updates to my other original thread - the UPS man came today and it was just a beautiful sight. Like Christmas all over again...
