Using “trickle-down” technology, inspired design, and performance cues from the Ultra-High-Resolution AlpineF#1Status systems, the Next-Generation R-Series Amplifiers feature High-Resolution Playback capabilities that will take this legendary system to the next level in sound performance. The Next-Generation R-Series amplifiers are Hi-Res Audio Certified and able to reproduce up to 45kHz frequency response. This ultra-wide bandwidth brings music even closer to the original source while the classic R-Series design maintains the “loud and fun” performance quality that long-time fans have come to enjoy. The R2-A60F features a reduced footprint that’s 15% smaller than the previous model (R-A60F), making it easier than ever to install in most vehicle applications while still getting the same powerhouse performance. Intentional designs were made to the amplifier that consolidated all speaker connections to one side of the amplifier for easy access. Amplifier controls were relocated to the top of the amplifier under a removable plate for convenient access to gain and crossover controls. To simplify the installation process, mounting “feet” are integrated onto the chassis of the amplifier.
