Why do you need car audio capacitors?
A loud and bassy car audio system is great, but it can also hinder other parts of your vehicle. An overpowered amplifier can drain the juice from your battery, dim the car's lights, or strain the alternator. To help alleviate any issues or potential damage, you should hook up a high-quality Recoil power capacitor. It works like a smaller version of your battery and stores energy to be used for other electronic components, such as the amplifier. 

Carbon/Electrolytic Hybrid Capacitor Technology

Electrolytic caps generally have a faster recharge rate but less power in their reserve. Carbon capacitors are the opposite of their electrolytic counterparts. While they are able to hold more power to divert back to the amplifier and the entire audio system, they will not be able to recharge as quickly. Recoil introduces a blend of both electrolytic and carbon capacitors, which have super-fast charge rates but also reserve more power.
