    I have a stock 105 amp alt. with the equip. in my sig. below. My lights blink on and off. I went to a local shop and they recomended that I go with a 180 amp alt. I believe that you will put out a lot more than me so I would go with something like around 200A or so.

    The guy at the alt. shop told me to take all the combine rms power of the system and devide it by 14. So, in your case, 1860 / 14 = 133 + (whatever power you need for the rest of the car: ~60-70A.) = 193 - 203A. I'm not saying that this is the correct way to figure this out, it's just what the guy at the shop said. Also, make sure that it puts out high amperage at idle also. Otherwise when your stopped haveing a HO alt. won't make a difference. Do some research, I'm sure that there is somebody on this forum that could give you the exact formula to figure it out. Hope this helped.

    I would say get a smaller stinger dry cell batt. Might put additional strain on the alt, but in the end it's way less strain then running both amps direct off the alt. These batt's are great for this. I would recommend them hands down.
