Maybe the amplifiers internal capacitors?

In my experience with all cars I had disconnected the bat neg terminal, when connecting it back, there is always a tiny spark or pop with the ignition key off or not even in the switch.

With the amplifier's ground or main fuse, connecting it, it is a much healthier spark and pop that happens every time.
