No. The circuit only draws as much current as it needs. Your car battery, unless you have a fuse in the circuit (which you should add, if you don't already have one) can supply much more than 6 amps - as much as a hundred amps or more under heavy load, like starting.ThirtyTwo said:could the op-amp be zapped by too high an amperage? The 12v on my car is at 6AMPS. When i was testing it on a computer power supply everything worked fine, but the 12v amps were really low
