just connect a receiver plug to it and plug it to your AUX or Batt Channel. If no spare channel you need a splitter.
You want to make sure that you use a LOW IMPEDANCE
electrolytic capacitor. Not all capacitors have the same properties, and the impedance is very important for propper operation. You can go up to 8200uf without having any problems.
Most of the capacitors sold at places like Radio Shack are of the normal type. You need something like a PANASONIC FC SERIES.
Most capacitors are rated at 85'C and you will do better with a 105'C cap. THE FC SERIES is the right capacitor for thos application. Other companies make LOW IMPEDANCE caps, but the easiest to get is the PAN FC.
If you need a source for this capacitors you can PM me.
BTW, WATCH THE POLARITY!
Hope this will help you.
