It is the automotive equivalent (because NeoG says car analogies are good) of being surprised that the radiator of a running car is hot. An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the power of a signal (a time-varying voltage or current).It is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude of a signal applied to its input terminals, producing a proportionally greater amplitude signal at its output. Class A mode gets really hot. If it does, and you're sure it's securely anchored to the panel and the wires are tight, there's probably something wrong with it. Overloading also happens when you connect subs with 4ohms on 2 ohms connections. By hot I mean you can barely stand to keep your hand on the amplifier back plate for any length of time.
