I go to the park alot and Like to play my music from the car as every one knows this drains the battery. so im wondering if I could rig up one of those water pump drive kits to run the alternator while the car is off so that I keep my battery charged and only use the jucie from the alternator
is this possable?

I believe you will find that the battery drains faster than it gets charged. It's kind of hard to come up with something to work perpetual motion. Might consider a second battery and a switch set-up like they use in campers.
