Car audio capacitors store electrical energy and release it to maintain proper current flow. This improves car amplifier performance, especially when power demand is great, such as when the volume of the music is loud. A car audio capacitor is installed on the power line leading from the battery of the vehicle to the amplifier it is serving. Installation only requires a few wire connections.
Instructions
1. Remove the end of the power line leading to the amplifier from the battery of your car.
2. Cut the power line in a spot about one foot from the amplifier with a pair of wire cutters.
3. Remove 1/2 inch of insulation from each end of the cut wire with a set of wire strippers.
4. Loosen the two terminals marked (+) on the capacitor with an Allen wrench until there is an opening large enough for the bare ends of the cut wire to be inserted. Slip the ends of the wire into the terminals--one wire per terminal--and tighten them with the Allen wrench.
5. Loosen the (-) terminal of the capacitor with the Allen wrench. Slide the end of the capacitor's ground cable into the opening then tighten the terminal.
6. Loosen the ground bolt for the amplifier with a wrench. Slide the end of the capacitor's ground wire under the bolt and tighten the bolt.
7. Replace the power line back onto the battery.
