The Rockford Fosgate R300-4 is a quad-channel, Class-A/B amplifier designed to power two full-range or component speakers in the front, and a 10” or 12” subwoofer in the back. It can output up to 75W per 4 channels, or 150W per 2 channels when bridged. Featured is a variable low-pass filter, selectable bass boost, and two sets of preamp inputs. Critics say the Rockford Fosgate R300-4 is an optimal choice for powering an entire audio system, so long as too many components aren’t strung together. Four midrange speakers or two midrange speakers and a subwoofer are recommended.
