I have a o9 dodge charger and i want to do two 15 inch icon subs,ansd a single saz 1500 or audioque 1200,would i be able to do the big3 and change battery to a kinetic and be fine on my electrical upgrade?

Too many variables to know for certain. If those pieces are what your prepared to begin with, then go for it. Hook up and try it out. Watch your volts or system performance and if you need more power then plan accordingly. A big factor will be to see what your current alt is capable of. My vote is that you should be okay.

I wouldn't change your starting battery, i would add a Kinetik in the trunk.. as for voltage you should be fine, so go for it

unless your starting battery is bad then i would replace it

Use at least 0 ga wire for power and ground and for the big3.

You could be good to go with these upgrades, but we don't know how (powerful)is your stock electrical system.

Do you have an amp for your mids?

I would do only one good AGM batt for this system. You will find out if it is enough by checking the voltage when playing.

You don't need 0 gauge for the big 3 by any means, but there's nothing wrong with overkill.

The first question that should be asked is how big is your alternator?

x2, and will there be any other amps in the install?
