So I have a 1991 Jetta Carat. It's my winter car. I have two 2200 watt amps that I want to hook up to my 2 subs. I want to set them at maybe 1500 watts maybe 1800. I want the amps to last. I am getting a yellow top optima battery and moving my other battery to my trunk. I will be running 4 gauge wiring. I did the math 3600 watts from the amps divided by the two batterys 24 volts combined = 150 amps + my car needs 65 amps to run itself. SO my brother and I are thinking we need a 215 amp alternator. But were afraid it's just going to be working itself non stop to power everything and we don't know if we can an alternator with that much amps to fit in my car. Will all of this work? Any suggestions or insight?
