He said just over 100 amps of constant power. The HC600 is about the same amperage of the stock battery, and not enough to fill my requirements. I know the combo of the HC1400 and HC600 is a bit of overkill but since my alternator is undersized I figured my batteries are in a state of constant drain. I'd rather have an abundance of power than not enough. I was wondering about fitting the HC1400 in the stock spot since it is a few hairs bigger... I thought it probably work but I won't have it until next week. Have you already tried this??? Does it work???

The formula used is as follows, ( power/efficiency )/ voltage
so if you have a 1000 watt amp that is 75% effecient then you need to offset a load of 95 amps.
Also you dont really need an isolator, that is only for if you are listening to the stereo for prolonged periods of time with the car off, the isolator just allows the front battery to remain charged while the sub stage is ran off the rear battery.
Does anyone know the actual current rating of the fit sport alternator?
