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.

I understand the safety issues... I'm arguing semantics here....

what type of load does say a 1,000w Class D amp or a 300watt A/B amp seriously have when it is not turned on... As in, the car is off, they key is not set to ACC, the radio is not turned on... but the battery is still connected.

I mean... shit... a bank of eight 2200uf caps doesn't really constitute a "load" when we are talking about kilowatt systems, 100+ amp fuses, and 4awg & 1/0awg cables.

I really have trouble believing that a short would EVER occur due to this, or that fuses would blow.

I honestly thing all the "car turned off, battery disconnected... yadda yadda yadda was introduced back in the day to prevent people who didn't know what they were doing from burning up cars and killing themselves.
