Product Description

Features & Specifications



Rockford Fosgate R2-1200X1 Prime 1200 Watt Mono Subwoofer Amplifier

Rockford Fosgate’s Prime Series R2-1200X1 amplifier can power your subwoofer with up to 1,200 watts RMS. You can adjust the low-pass filter, infrasonic filter, and Rockford Fosgate’s famous Punch boost to get the best possible bass from the sub and enclosure in your vehicle. For subwoofers, a variable infrasonic filter and remote level control allows you to tune the bass for the desired level for the music.

Setting it up for optimum performance

Rockford Fosgate’s C.L.E.A.N. technology (Calibrated Level Eliminates Audible Noise) setup system ensures your bass will sound as clean and powerful as possible. It’s a simple system to use — turn it up until the light shows red, then turn it down until the red light goes out. Speaker-level inputs let you hook this amp up to almost any system, even a factory stereo.

Give your sub the power it deserves

The R2 models are developed for car audio fanatics that want a reliable amplifier – with all the power and performance you’ve come to expect from Rockford Fosgate – at an economical price. Rockford Fosgate amplifiers are renowned world-wide for being “under rated,” easily surpassing all specifications, and most importantly, generating more power than their ratings. These 3rd generation of Prime Series amplifiers are refined with the latest Rockford Fosgate technology for easy setup and configuration, making them perfect for use with factory audio or custom aftermarket systems.
