[QUOTE="Johnny Drama, post: 2385002, member: 554719"] 100.2 is going to be ~14a max draw each 1500d will be ~140a max so you aer looking at ~70a for both on a daily setup. You will need atleast 84a extra current bare minimum. You car is going to need about 60% of your current alternators amperage to run so whatever that is take the A and multiply it by .60 to see what the car needs. Then find one with an amount that will not overload it. Finally...an extra set of batterys will help out with the amperage demands. I dont see you keeping a good 14v charge however. I am a little drunk so someone please check my math. [/QUOTE]
