Saturn Repair: dead battery, ground cable, test light

Question
my battery keeps dying.  I have a sony explode amplifier installed to the battery.  It turns like it wants to crank but doesn't then after a while it doesn't make a sound.  later if i go back to start it it starts unless the battery is dead what is killing my battery(1992 saturn twin cam)(sport)

Answer
Hi well im cant really say but how old is the battery and is it any good if its gone dead a few time the battery is most likly no more good  what u need to do is get a test light and take the ground off from the battery and connect the test light between the ground cable and the battery and the light will light up if its bright u have a draw the u just pull fuses untill the light goes dim or off and then what ever fuse u pulled is the problem.   good luck
