How do Dry cell batteries used in your audio system?

Well, everyone says to use dry cell batteries in your car because it will help. How does it work? Do I need to hook up the battery to the alternator or will it recharge itself? And I have one query more. Why does everyone use dry cell batteries specifically for audio systems in the car most of the times? I would really appreciate an early response from you guys out there. Thanks.
