The frequency of the current taken by the amplifier is not zero. It goes with the audio signal for a class B amplifier.

I think the biggest problem of connecting a capacitor to a battery is that the battery voltage is near constant
I believe we have gotten off subject here.Stefan's question has nothing to do with audio.I believe the question is how to integrate a supercapacitor to a lead acid battery in order to extend its life in high charge/discharge environments. As in electric/hybrid vehicles or power generation from wind or other highly sporadic energy sources. Lead acid batteries do not take well to being drained down real low, charged fast, or over charged. These conditions shorten the life of the battery. The capacitor is supposed to act as some sort of a buffer being able to take quick charge/discharge cycles. I am not sure what all is involved, but these people sell the supercaps & related equipment. http://www.maxfarad.com/Capacitor are used with bass speakers(sub woofer) to filter out the high frequencies so that only the bass frequencies reach the driver(speaker).
