Question about Car Audio & Video Accessories
Precedent golf carts have a 48 volt system. Generally they have either 4 twelve volt batteries or 6 eight volt batteries under the seat. Unlike automobiles, golf cars do not have a grounded system; the electrical system is isolated from the chassis. This means you will have to run both the positive and the negative wires from your source to the stereo. Some carts come with a "converter" described below, check with Club Car or your dealer to see if yours came equipped with one. Club Car and their dealers are generally very helpful about answering questions like this. One way to check is if your car has an accessory 12v outlet (cig lighter). If it does, you have a converter. You can also tap into this circuit for your power if you aren't connecting amps and such, they would draw too much power. If yours doesn't have a converter, then follow one of the procedures below.
If your car has 4 twelve volt batteries you can simply connect your stereo to the positive and negative posts of one of the batteries and you will have a working system. Most "experts" do not recommend this method; it causes an uneven draw on your battery pack and the battery you draw the power from will not last quite as long as the rest of the pack.
The recommended method is to purchase a voltage converter. This is the only option if you have 8 volt batteries and want to power your stereo from your battery pack. This converter connects to your 48 volt system and converts it to 12 volts for your accessories. This draws on all of your batteries equally and is better for battery life.
Another option is to purchase a separate deep cycle battery, such as the Optima, and mount it in your cart just for the options. The nice thing about this method is that it does not take any of the power from your battery pack, thereby having no effect on range. It not too hard to find a place to mount an extra battery and a $30 auto battery charger will keep it charged. Just plug it in when you plug in the cart to charge.
A good source of information are the BuggiesUnlimited.com foums. They have some wiring diagrams posted, if yours is not there ask and someone will post it.

There is another method to connect your radio. Under the cover where the run/tow switch is, there is a blue wire that is not connected to anything (assuming that no one has connected anything that requires 12 volts yet. Connect this wire to the front battery on the passenger side, Should be a wire already there on the neg post but not connected. This connection supplies 12 v to the wiring harness. Now remove the three screws holding the dash on,( torx screws) should be a plastic connector thats not connected. I forget the colors maybe white and black but two outside pins should give you 12 volts, use a voltmeter to check.

You have to buy a 12 volt converter to install a radio on a 48 volt system. I bought mine on e-bay to put my radio on my 2001 Club Car. Garry

Negative to positive all the way around until you get to your main positive and negative
