Do I need to get another battery, do I need a capacitor and if so what farad, do I need to do something with my alternator, upgrade or something, what gauge power wires do i need, what gauge speaker wires, and is there anything else?
do i really have to do something to the alternator because i don't really have a lot of money yet so does that have to be done right away
 
i can tell you that you might need to upgrade your alternator to a 120 amp or so because the stock one can only pull about 80 amps and when you play your music in the night your lights are going to dim.
