Yes you can, The battery is in the back of the trunk, you hook your amp up to the battery and then the amp to the sub, you need to buy a converter for the back speaker, you can buy one from any car audio shop, you then splice the wires in the back and hook up your converter, then hook the converter to the amp, But get it professionally installed because my buddy tried to do it with his magnum and it started to blow fuses, It shocked him today, he is going to get it professionally done today

Usually a car battery, but it also depends on the size of the battery.
There are 2 ways you can go You can hook them up in series or in parallel If you hook them up in series That is you connect the positive side of the battery to the negative side of the next battery and so on you en up with the voltage being increased by the voltage of each battery So if you hook up a 12 volt battery to the end of a 6 volt battery you end up with 18 volts. Or you can hook them up in parallel That is you hook the abaterys together on one side going from positive to positive and on the other side negative to negative When you do this you end up with the same voltage but increase the amperage.
