Ok, it took me a while to think of the right way to ask this but I think I got it:
What limits how many amperes your amplifer is taking in? I am guessing that the alternator limits the ampere output for long periods of time (for example my amplifer should not take more than 105 amperes because that is the highest amount that my alt puts out) but what about when the car is off? What limits the ampere output when the car is off???? I mean, I know that it is the battery but will the battery be able to put out more than 105 amperes while the car is off??? Is this where deep cycle batterys come into play????
Also, the same goes for voltage. Can you regulate voltage amounts some how? Say, for example, when the car is off I have 12.5v but I need 13-14 volts? Can you raise the voltage by any means when the car is off??
Thank you very much for any help

. I am sure these questions are hard core to answer so thnx fer takin the time
