[QUOTE="Nerdy1980s, post: 8746357, member: 683073"] Batteries provide power on demand. Each cell has a certain amount of energy. To drive a large sound system needs a massive amount of power when it first boots. Sorta like a laser printer: it uses a certain amount of continuous energy when running, but when it first turns on, it uses a massive amount of energy all at once. Even a desktop laser printer can cause lights in the room to flicker momentarily when it first turns on, especially in an older house. I'm not an engineer, but I think it's the amplifiers that need that initial boost of electricity to power up, and maybe the subwoofer also. Not sure on the subwoofer though. This is merely speculation anyway. [/QUOTE]
