Some people put extra large sound systems in their cars to give a bigger subwoofer effect. The problem with this is that not only do some people find loud music annoying, these big audio systems can actually make your alternator and charging system work overtime, and as a result, will rapidly drain your battery. Not only will the battery have to be replaced frequently, the alternator can fail prematurely as well. Since the alternator keeps the battery charged, the car might not run right or may stop running altogether. But, if you insist on installing one of these audio systems, you might want to consider also installing a high-output alternator.
