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.
