R2-1200X1

The Rockford Fosgate R2-1200X1 from the Prime Series is a powerful digital 1-channel mono amplifier designed specifically to drive high-output subwoofers. With up to 1,200 watts RMS at 1 ohm, this compact Class D amplifier offers high power reserves and efficient amplification for powerful, controlled bass reproduction.

The built-in C.L.E.A.N. technology makes it easy to precisely adjust the input level and helps prevent signal distortion. The variable Punch EQ allows for targeted bass boost, while the adjustable low-pass and infrasonic filters enable optimal adjustment to the connected subwoofer.

Thanks to its balanced differential inputs, high-level connections with automatic power-on functionality, and RCA loop-through outputs, the R2-1200X1 can be flexibly integrated into both existing and new car audio systems. A solid die-cast aluminum heat sink ensures reliable heat dissipation.
