Product Description

Rockford Fosgate R1200-1D Prime 1,200W Class-D Mono Amp

The PRIME R1200-1D 1200 watt amp is an ultra-efficient mono amplifier for cars and trucks stable down to a 1-Ohm load without taxing the electrical system. The frequency response of the R1200-1D is optimized exclusively for use with subwoofers.

The Prime R1200-1D subwoofer amplifier offers high efficiency through the implementation of its Class D circuitry while delivering rich, full bass to any system. This car amplifier is optimized for subwoofers with the implementation of an infrasonic filter to keep those ultra-low (inaudible) bass notes from damaging your subwoofer system. Match with a 4-channel stereo amplifier for your mids/highs and you’ll have a Rockford Fosgate system that any Car Audio Fanatic will envy.

CEA-2006 Compliant CE Compliant Class D

CEA-2006 Compliant

Power ratings on Rockford Fosgate amplifiers conform to CEA-2006 industry standards. These guidelines mean your amplifier's output power ratings are REAL POWER numbers, not inflated marketing ratings.

CE Compliant

This product fulfills all essential safety and environmental requirements as defined in the European Directives (768/2008 EC).

Class D

High efficiency amplifier design that reduces current consumption from the charging system.
