Car Batteries, Alternators and Capacitors

In order to enjoy a pounding car audio system, you'll need to invest in your car's electrical system since most cars are not intended to run aftermarket audio setups. Having a high quality car audio setup can be taxing on the car's electrical system. This is where upgrading your car battery, alternator or the wiring comes in. These aftermarket car batteries and high output alternators are designed to supply an aftermarket audio system. If you're experiencing headlight dimming when playing your music, this is a sign that you should invest in a car battery or alternator. You can even look into adding a capacitor as a temporary solution. If adding a capacitor to fix a problem like headlight dimming, it would be better to add a high output car battery, alternator or upgrade the wiring when you can.
