[QUOTE="Ryan shaw, post: 7151082, member: 627561"] I have done some research on charging systems and i keep seeing that your alternator is the only thing supplying power to your amps with the car on. So if this is true by my understanding, the only thing second batteries do is prolong your car off listening time? or is it something like extra batteries give you more instantly available power to reduce voltage drop on heavy current draw notes? I guess i just dont see why everyone with high power systems seem to always have at least 1 battery in the back if all it does is prolong your car off listening time. please correct me if i'm wrong, which i probably am lol, thanks!
