Default 1 farad = 1,000,000.uf

and if so how do they make the auto audio 1 farad cap so small?

Small ? I don't think so... And they have only ~16volts

Roughly put:

cap-size ~ capacitance x voltage handling

the size of the cap is porportional to it's capacitance and voltage handling.

So, if you only need a small amount of voltage handling, you can make the capacitance fairly high in a pretty small size. Such as those 1F 5v caps that are the size of a few poker chips stacked.

Those 1F car caps are not that small...

the caps are usually rated at 20-25V DC,

I don't think they are small considering the size and voltage rating.

for size comparisons, I usually multiply the voltage and capacitance ratings. (pointless but it makes some sense. )

so if the cap is 20v X 1000000uF, it would be approximately the same size as 100V 200000uF.

I have 4 15,000uf caps and combined they are larger in physical size then a 1 farad cap. So it is the voltage rating that makes the difference.

capasitor size ~ capacitance x (voltage) ^2
