Rockford Fosgate R-300X4 Prime 300W 4-Channel Class D Prime Series Full Range Amplifier + Absolute 4 Gauge Amp Kit Rockford Fosgate amplification is at an unbelievable value. The R300X4 4-channel amplifier is so versatile that it will be your system's only amplifier. Full-range or component speakers on the front channels and a single R1S410 10" or R1S412 12" woofer bridged/mono on the rear. Consider your system clean, loud, and done!Class-DAn amplifier topology with the best of both worlds; a Class A preamp and Class B output stage. Class A topologies are great for sound quality but can require a lot of currents. Class B designs are great for power delivery. Amplifier designs utilizing a Class A/B topology reap the benefit of great sound quality in the front end (preamplifier stage) while delivering great power in the output stages (MOSFET drivers).
