You don't need a capacitor. You don't need a battery unless yours is bad or has been discharged and recharged several times.

You NEED an amp to power a sub. First figure out what the rms of that sub is, then get an amp that runs close to that rms at 4 ohms. If you're running one sub, get a mono amp. Two subs, get a 2 channel.

You need an amp power kit and RCAs. You also need a professional to install this for you. They should be able to help you pick out what amp based on your budget and needs.
