The same as you read at the battery.

if the car is running, youre going to want to see around 14.4 volts, if its off, 12.4. Bear in mind that you will lose some voltage over a length of cable, but the loss shouldnt be too much. Just do yourself a favor and get a voltage meter like this one  and connect it to the positive terminal of your amp and put the display up by your deck. Calibrate it and you should never see below 12 volts on that meter when banging or youre risking damage to your amp

Are you trying to set the gain on the amp or are you asking what the voltage should be coming from the battery?

Don't confuse him.

let's take an exemple :

Hmm, lets see what we'd need for .1 second of discharge. V(t) = V0 * e^(-t/RC) C = - t / (R * ln (V(t) / V0)) C = -.1 / (.003 * ln(3/6)) C = 48 Farads Now a cap that large would need the ESR/ESL factored in as well, and hopefully the electrolyte wouldn't get cooked out from the heat of discharge.
