Alpine's legendary R-Series
Alpine R-Series includes amplifiers, subwoofers, component sets and coaxial speakers. Over the years, the R-Series has become synonymous with the best possible sound quality, performance and reliability for car audio systems.
The new R-Series amplifiers further reinforce this reputation.
R2-A150M is the larger Class D mono amplifier in Alpine's updated R-Series range.
The perfect amplifier for two or more subwoofers
The R2-A150M is the perfect amplifier for powering two R2-Series 10″ or 12″ subwoofers, or even four 7-inch “angry” subwoofers.
Regardless of the number of subwoofers, a single R2-A150M amplifier provides plenty of power for low frequencies!
Versatile adjustment options
You will find all the amplifier controls under the cover of the R2-A150M. The subsonic filter allows you to cut out the lowest frequencies (8Hz–40Hz), while the low-pass filter is adjustable from 50 to 400Hz. Both the subsonic and low-pass filters have a 24dB slope. The amplifier also features a Bass EQ, allowing you to boost the subwoofer level (0 to +12dB) at 50Hz.
Easier installation
The amplifier has also been designed with installation and ease of use in mind. All power, speaker and RCA connections are located on the same side, and all the amplifier controls are found under the cover on top of the amplifier.
The amplifier also does not have separate mounting feet, as the mounting holes are integrated into the amplifier chassis.
RUX-Knob2
The Alpine R2-A150M is compatible with the RUX-Knob2 level control sold as an accessory.
The R2-A150M is the perfect amplifier for R-Series subwoofers
All R-Series amplifiers are designed to be the perfect match for R-Series subwoofers and speaker sets.
R-Series coaxials and component sets are also Hi-Res Audio certified.
