Chances are for the subs and the amount of power you want to run you will need electrical upgrades.. Big 3 at least. If you are going to run at .5 ohm you will need an amp stable to that rating as well as at least one battery, heavy guage power and ground and possibly a battery. If you run at 1 or 2 ohm you could get off a little easier but not a lot.
