I was told by someone that i will be needing a new alternator. He said this cuz im getting a new Infinity 1211a amp which is 40A x 3 = 120A fuses. I dont think i will, but i need headlights at night. What do you think. Thanks for any replies in advance.
if you running a stock alternator there is no way you can run that amp without a new alternator, my rangers stock alt is 95A, most other vehicles are around there too. And you need another 50A on top of your amp draw to run the rest of your vehicles electronics.
