How to ground my Amp on Yaris Hatchback - Toyota Yaris Forums

Not pulling punches here... It is just plain stupid to perform any any electrical wiring with the battery connected. Takes 30 seconds to disconnect the negative cable... The spark here vs. the spark there concept is totally erroneous. The spark at the negative terminal that occurs when reconnecting the battery is not an issue... the spark occurs at a point where current normally flows, and is usually small unless you have a large load that is just waiting for the current path to be restored (NOT A GOOD IDEA). The spark that occurs when you're connecting a piece of equipment and you are too lazy or too stupid to disconnect the battery first, will usually put a large current where you don't want a large current (I.E. A SHORT) ---> fuses blow and or said equipment or something else stops working.
