Sorry, but a stiffening cap is worthless. Do the math for the voltage
swing on the cap and compare it to that of the battery. The capacitor
is insignificant.

You'd need to be drawing surges over 250 Amps before a cap became
worthwhile, and it would have to be a ****load bigger than a few Farads.
Effort would be better spent on adding a second battery with a very high
cranking rating.

Even handheld mobile transmitters use capacitors of 1F to 5F. Putting a
few F on a high powered audio amp is like waxing your car to make it go
faster.

what makes a cap worthless, in the car system with a lowly 12vrms the cap is
very necessary. I just want to know what you base your statement on??
