My stock alt is 120 amp's and im running regular range rover electronics and my kicker KX350.2 which has a 50 amp fuse. now im wandering how much power my massive P3000.1 is seeing before it drops to battery power? im guessing about 1000 watts tops, but who knows, im not that educated in the electrical field so i was hopin someone who is (MS,Wolfie,paul,Polo) or anyone who wants to guess could help out.
