Why is this cap so big?
May 12, 2010
So I am installing a new stereo in my truck (I have done custom, high-end installs for years) and am including a power cap as I always do. These caps are standard in the mobile audio world to keep your headlights from dimming and to keep your alternator from being over-worked.
Question: Why are these things so big? I mean, the 10F super cap is just slightly bigger than a "standard" cap where as this one is almost the size of an oatmeal can at only 2 farad.
Just for some additional info, this particular install has a final output of around 1600 watts total.
Why is this so big?!?!?
