Alpine R2-A150M Amplifier 1 Channel Monoblock Subwoofer Class D 1500w RMS
R2-A150M
The Alpine “R-Series” line of speakers, subwoofers and amplifiers have a heritage of sound quality you can hear from a block away, and the newly added R-Series amplifiers are no exception. Aside from their best-in-class performance, these amplifiers are tuned to emphasize the characteristics of the R-Series speakers and subwoofers, giving you that legendary R-Series experience. They have a 15% reduced footprint compared to the previous models and are easier to install.
If you like your music loud and clear, our Alpine R-Series R2-A150M mono amplifier is for you. It cleanly reproduces the bass in your music so you can enjoy the enhanced realism you want, even when you're playing High-Res music. We built some of our top-of-the-line amplifier technology into this R2-Series amp, including high-efficiency transformers, premium low-noise custom capacitors, and low-distortion dual "Sierra" feedback/correction circuitry.
The R2-A150M mono amplifier produces up to 1200 watts RMS @ 2 Ohms, making it a perfect match for the Alpine R-Series subwoofer line. Advanced Class-D amp technology makes this powerful amp small enough to fit almost any location. You can adjust the amp's low-pass filter, bass boost, and subsonic filter to get just the right bass tone. Plus, you can add the optional RUX-KNOB2 remote bass knob to control your bass from the dash.
R-Series amplifiers are available in two mono and a 4-channel configuration.
Simplified Installation
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 brackets are integrated onto the chassis of the amplifier.
Elevate Your Audio
Elevate your audio with the Alpine R2-A150M Mono Amplifier - delivering powerful 1200W performance @ 2 Ohms in a sleek, compact design. Built with Alpine's cutting-edge Class-D Amplifier Circuit, this next-generation R-Series amp offers exceptional sound quality and efficiency, making it the perfect addition to any car audio system.
Perfect Power-Match for Multiple R-Series Subs
The R2-A150M is designed to exactly match the power handling of two 10” or 12” R-Series subwoofers – or even four 8” R-Series subs (1200 Watts @ 2 Ohms). Simply build a large subwoofer system in your vehicle and run it with one single R2-A150M mono amp.
Extensive Tuning Options
The R2-A150M features intentional design choices that prioritize convenience and simplicity. All speaker connections are consolidated on one side of the device for easy access, while the amplifier controls have been relocated to the top under a removable plate, allowing for quick adjustments to gain and crossover controls. The amplifier’s chassis also includes integrated mounting “feet” to streamline the installation process.
Remote Bass Knob Ready
You can connect the RUX-KNOB2 remote bass knob (optional available) to the R2-A150M to control the subwoofer level straight from your dash.

FAQs
Q: How do I choose the right amplifier for my speakers or subwoofer?
A: Match the amplifier's RMS output per channel to the RMS handling of your speakers or subwoofer at the same impedance. The Specification tab lists the power figures. If in doubt, contact CEN with your setup and we will recommend a match.
Q: What wiring do I need to install this amplifier?
A: You will need an amplifier wiring kit sized to the amplifier's power draw, typically including power and earth cable, a fuse, RCA leads and a remote wire. CEN stocks complete wiring kits, and the amplifier's fuse rating is the guide to the cable gauge required.
Q: What class of amplifier is this and does it matter?
A: Class D amplifiers are compact and efficient, ideal for subwoofers and modern installs. Class AB designs are traditionally favoured for outright sound quality on mid and high frequencies. The class is listed in the Specification tab where provided.
Q: Will an amplifier work with my factory head unit?
A: Yes, in most cases. If your head unit has no RCA outputs you will need a line output converter to feed the amplifier a clean signal. CEN stocks line output converters and can advise the right one for your vehicle.
Q: Can CEN install this amplifier?
A: Yes. CEN offers professional amplifier installation from our Nottingham premises, including secure mounting, wiring and setup. Contact us to book.
