first of all
your dumb for putting a system on a golf cart
secondly, you can NOT just use a standard car battery, they do not put out enough power and will die in a matter of minutes
third, your going to need an optima yellow top or kinetik power cell, AT LEAST 3 of them because this is your ONLY source of power *which are $300+ each, you can not get these by tomorrow night)
fourth, the batteries will eventually die because there is nothing to help charge the batteries, so you have not even 20 minutes of playing time
fifth, you can NOT wire three 12 inch subs and two 6x9s on the same amp, this will be too much for the amp, and it will short out and blow the amp
sixth, you need a seperate amp for the three 12" subs and 6x9s
seventh, this is dumb and retarded i hope you get shot for even THINKING of this idea
eighth, dont do it dumbass
