question about alternator

[plokkr123]

I drive a Honda Accord 2002 EX V 6 with a stock alternator rated at 100amp. I was just wondering if the alternator is sufficient enough to power a Planet Audio p704 4 ch amp (made by Zed) at 70x4 ohm and a (pos) MTX Jackhammer JH600 wired at 350x1 4ohm. I used a Excel spreadsheet calculator I found on the net for current draw that told me it was sufficient, but I don't know if it means with other electronics turned off or with. Should I replace my stock with a bigger alternator?

alternator is the ladt thing on the list. it will be plenty enough due to the efficiency of the amp there is no way it will draw enough amps to do any damage. if need be upgrade your power wire, or get a .5 fared cap if really needed.

you fail

stfu and go away

OP, upgrade your front battery. honda batts are small and ****. if you notice a lot of dimming occurring while running your setup then try a Big 3 install. if you still have a dimming issue then get yourself a deep cell battery and place in the trunk.

overall you don't need an HO alt with that kinda amperage pull.

I forgot to mention the mono amp is wired to a capacitor. I'm not sure if I should have wired both the amps to the cap. I also replaced the stock battery with a Die Hard gold north.
