The first word that comes to mind is Google.
But let's see if I can explain this myself.
The Amplifier(amp) is connected to the Head Unit(HU) with an RCA cable.
The amp is connected to the battery with a large gauge(4/8) wire.
The Subwoofer does not exactly get power, per say, but it does get its signal from the amplifer(which in reality, is power).
Hope that answers your questions.
