Hi, I'm hooking up my amplifier to the battery, but the bolt that would hold down the ring terminals is missing. How would I figure out what size bolt I need? 
Also, if I connect the wire to the battery without the bolt and nothing turns on, should I be worried? Or does it not work unless it's fastened down?
JesusDIC - I had it hooked up before and it didn't drain it. I have it going to a switch that I turn on/off so it doesn't do that.
