Ok here's the deal in short:
the big three alone won't make a difference most times, as the factory wiring is sufficient for the stock alternator. Increasing the current flow capability of the wiring won't increase the output of the alternator, which is the source of current for a running car. :)
that said, the alternator is what needs to be bigger when the car is running, to supply more juice for the audio system.
a second, isolated deep cycle battery is ideal for running a system with the car off, and will help additionally to stablize voltage rails for brief durations with the car running.. however don't misinterpret this. If the alternator can't keep up, it doesn't matter what batteries you use, they'll still drain without a chance to recharge since they won't see the 13.8 or higher voltage rails required to recharge them.
