The Poor Man's Capacitor
Do your headlights dim when your car stereo hits that low bass at night? If they do, that is bad news. That means that your alternator can't supply enough power for that high current draw, and this can damage your alternator over time, or even destroy it. To solve this problem is simple, create another temporary power source for your amplifier to draw power from. This can be accomplished most easily in two ways:
1. Install a second battery
2. Install a capacitor
The first option is the best since a second battery can supply a lot of extra electricity, but some do not want to purchase another battery. For those people, they must get a device known as a capacitor. A capacitor is very much like a battery, only it doesn't use chemicals to supply electricity. It only stores electricity for fairly short periods of time on charged metal plates. But doesn't a large capacitor cost big $? Yes, but there is another solution. If you want to save that $100 that it would take to buy an overpriced brand-name capacitor, go into your supply of salvaged capacitors and wir them together in parallel. This means connecting positive to positive, negative to negative. In this way, the charge is added up into a sum, which can easily reach a level that can fix your problem. Of course, your capacitors must be rated at least 12V so that they are not destroyed due to excess voltage.
Remember, to do this you need a number of fairly large salvaged capacitors, not small ones. If you do not have any capacitors, check out the salvage page for information on where to find them.
