I am setting up 3 extra batterys in my car to run my stereo, all 3 extra batterys are the same.
So how i planed to set it up was a power cable running from my car original battery to the first extra battery in my trunk which its negative will be grounded to the car. the third battery will be connected to the second one and the fourth to the third.
Between the first and second i am going to put an isolator.
What size isolator should i use (the max amp) i have a 85 amp alternator. So will a 120 be more then enough?
Can you see anything wrong with my set up?
Any help will be appreciated.
i cant get a larger alternator as i need a certain one and its impossible to get one.
also im making it so the car can run while off and the alternator isn't on while the car is off
