depends what kind of budget your in? you could keep your stock alternator and get 2 bigger batts and you would be ok. But if you want it to be done the right way do the bige 3

1) Your system draws amps, not watts. 2) How many amps is your stock alt 3) I suggest getting a bigger alternator and a good main battery.

bigger batts are only covering your problem up your guna work that poor alt to death... now its got to charge both them batterys the right thing to do is get a HO alt and do the big 3
