I'm new here so bare with me. I have 2 power acoustic mofo 124x 12 inch 4 ohm dual voicecoils subwoofers running at 1500 watts rms each (3000 watts rms together). They are both wired parrel for 2 ohms each and wired to together at the amp for 1 ohm. I have a skar audio RP-4500.1d mono block amplifier pushing these subs. My question is do I need to upgrade my charging system to 2 high output alternators and 2 batteries along with the big 3? I did the math with the ohms law and just for my audio system alone I need 450 amps. I figured two 300 amp output alternators should be plenty. Am I right or is this overkill? If I'm wrong help me and gave me some advice on what I should do. Thanks in advance.

Welcome to SSA Joshua, you made the right choice.  I vote that you do one alt, batteries, BIG3.  Then if you are seeing voltage drop after that, then sort out second alternator and alt bracket and alt belts.

 

Side note, we carry great alts, batteries, and wire on the SSA store.
