Rockford Fosgate amplification at an unbelievable value. The R300X4 4-channel amplifier is so versatile, it will be the only amplifier your system needs. 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-ABAn amplifier topology with the best of both worlds; a Class A preamp and Class B output stage. Class A topologies area great for sound quality but can require alot of current. Class B designs are great for power delivery. Amplifier designs utilizing a Class A/B topology reaps the benefit of great sound quality in the front-end (preamplifier stage) while delivering great power in the output stages (MOSFET drivers).

great amp for great price
This amp is powerful. Mine was rated at 402w rms. I have 2 6.5, 2 6x9, 2 5x7. Is not even half way up and they scream. Ordering 2 sets of Rockford p165 and 2 sets of p1692. Should sound better and cleaner. Rockford never disappoints me. Great product!

Plenty of power to run your system & extremely easy to set up I use it powering Polk db5252 components in the front & Polk db692 in the rear ran through a Kenwood X-599 deck & I have a Rockford 12" punch series sub in the trunk (not ran through this amp) & it really brings the musical experience to life
