How do I hook up a second car battery?

How do you hook up a resister to a car battery to charge a car audio capacitor?

• im clueless on how to do this. if someone with the knowledge can guide me through this step by step it would be greatly appreciated!

• Answer:

  Easy, if you insist on having the capacitor there for garnish (looks), hook the system up but leave the fuse by the battery out. When done wiring it up reconnect the battery negative terminal as usual and hook the resistor up to the terminals of the fuse holder, once the cap is charged quickly remove the resistor and install the fuse. I will repost my other answer: Capacitors do work it is just that the whole "1 farad per 1000 watts" thing is woefully undersized. 1 farad means that the voltage will change at a rate of 1 volt per second at a current of 1 amp, hence if the bass hits and your amplifier draws 50 amps from the cap it will drop 1 volt in .02 seconds, that is 20 milliseconds, AKA 1 cycle @ 50Hz, not even a full drum beat. This doesn't even account for the ESR losses. I say you need about 100 farads per 1000 watts. Now try 6 Maxwell 3000 farad supercapacitors in series for 500 farads at a max of 16.2 volts, 15 working volts. 17.1 one time surge volts. 500 farads would take 10 seconds to drop 1 volt and 6 in series has an ESR of 1.74 milliohms so: 50 amps to the amplifier starting at 14.4 volts means that the voltage would immediately fall to 14.31 and then decay to 13.31 over the next 10 seconds, as you can see this would be more than enough for an almost any sound system. These capacitors are even powerful enough to start a car through cheap jumper cables. They would also take about 2 hours to pre-charge from a 1 amp constant current source such as a car tail light bulb and and car battery.
