I have 3000 watts rms in my boat so the stock alt does not keep up with the amp draw but a good on shore charger is key so ur batts are conditioned for the day. I use the pro mariner pro sport 20 plus. Alternators suck as batterie charger anyway. Now I have also ordered a mech man 170 amp alt for my boat to help things out a bit but this is not neccary
I don't see myself having 3000 watts of sound, maybe next summer. Looking at a 1200w 2 channel amp that should put a true 150w to the tower & I am not sure what is in the boat yet. I am deff doing that power plus thing though, I was reading up on that yesterday
