subwoofer (or sub) is mainly a loudspeaker designed to reproduce low-pitched audio frequencies known as bass and sub-bass, lower in rate than those which can be (optimally) generated by a woofer.

An amplifier or amp is an electronic device that can increase the power of an input signal. It is a two-port electronic circuit that takes electric power from power supply to increase the amplitude of a signal which is applied to its input terminals, producing a proportionally higher amplitude signal compared to its input signal at its output. The amount of amplification is measured by its gain, which is the ratio of output voltage, current, or power to input. The amplifier is a circuit which has a power gain higher than one.

We have a list of some best quality subwoofer amplifiers:

1.     Rockford Fosgate PRIME R750-1D:
