About the Alpine R2-A60F
The realistic sound you want
Into Hi-Res music? Alpine’s R2-Series R2-A60F amplifier reproduces high-frequency sounds up to 45,000 Hz, so you can enjoy the crystal-clear sound and enhanced realism you want in your music. Alpine has built some of its 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. Whether playing high- or standard-resolution music files, you can count on superior sound quality from this amp.How much power?
The R2-A60F 4-channel amp produces 100 watts RMS per channel, perfectly matching the power ratings of Alpine’s R-Series speakers. You can also use this versatile amp in 3-channel mode, driving a pair of speakers with the front channels, and bridging the rear channels to send up to 300 watts RMS to a subwoofer. Advanced Class D amp technology allows this powerful amp to be built small enough to fit in almost any location.Tone control for all configurations
The high-pass filters remove extreme low bass from your full-range speakers, so they’ll play more efficiently. If you plan to use your R2-A60F to run subwoofers, you can adjust the low-pass filters to get just the right bass tone. Best of all, you can set up the filters for bandpass operation, so you can use this amp to power tweeters and midrange drivers, and use a separate amp like a matching Alpine R2-A75M 750-watt or an R2-A150M 1500-watt amp to power your sub.

Product Research
Features
Overview: The Alpine R2-A60F 4-channel amplifier is effectively two full range 2-channel amps built into one chassis, labeled Channel 1/2 and Channel 3/4. Each section of the amp is bridgeable, so it can be wired as 4-channel, 3-channel, or 2-channel.
CTA-2006 Compliant: CTA-2006 is a system of testing and measurement for mobile audio amplifiers. This voluntary standard advocates a uniform method for measuring an amplifier’s RMS power output and signal-to-noise ratio. The criteria for measuring amplifier power uses a DC input voltage of 14.4 volts and the RMS power output is measured over a frequency range of 20 Hz to 20 kHz (for full range amplifiers), with 1% or less Total Harmonic Distortion plus noise (THD+N). Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4 ohms. CTA-2006 standards allow consumers to compare car amplifiers and receivers under the same conditions (apples to apples).
CTA-2006 Specifications:
- Power Output: 100 watts RMS x 4 into 4Ω
- Signal to Noise Ratio: 80 dBA (measured at 1 watt into 4Ω)
Other Specifications:
- Power Output:
- 2Ω: 150 watts RMS x 4 (14.4 volts, =1.0% THD+N)
- Bridged: 300 watts RMS x 2 (14.4 volts, 4Ω)
- Signal to Noise Ratio: 100 dB (at rated power output, 4Ω)
Hi-Res Frequency Response: The Alpine R2-A60F offers a wide frequency range for compatibility with Hi-Resolution Audio.
- +0/-3 dB (1W into 4Ω): 10 Hz – 45 kHz
- +0/-1 dB (1W into 4Ω): 20 Hz – 20 kHz
Controls
Gain Control: There are independent rotary gain controls for the two sections of the amplifier (Channel 1/2 and Channel 3/4). The amp will accept line level signals from 0.2 volts to 4.0 volts or speaker level signals from 0.5 volts to 10 volts.
Input Level: Set the input level switch to match the type of input signal used (Hi for speaker level and Lo for line level).
Input Channel: The Input Channel switch is set to 1/2 if you have a 2-channel input signal, and an identical signal is sent to channels 1/2 and channels 3/4. Set the switch to 3/4 if you have a 4-channel source.
Turn-On: A 2-way switch determines the activation method for the amplifier; REM, when using a remote turn-on lead from a headunit; DC, the amp is activated by DC voltage when connecting speaker-level inputs.
Crossovers: Channels 1/2 and 3/4 have independent crossovers. Each crossover has a 4-position switch to direct how it operates and both crossovers have a slope of 12dB/octave.
- Channel 1/2:
- Off: output is full range
- HP: High Pass; crossover point is adjustable from 50 Hz to 400 Hz
- LP: Low Pass; crossover point is adjustable from 50 Hz to 400 Hz
- HP-H: used when powering a pair of tweeters; crossover point is adjustable from 400 Hz to 6 kHz
- Channel 3/4:
- Off: output is full range
- HP: High Pass; crossover point is adjustable from 50 Hz to 400 Hz
- LP: Low Pass; crossover point is adjustable from 50 Hz to 400 Hz
- BP: Band Pass; two crossover points are set, high pass is adjustable from 50 Hz to 400 Hz and the low pass is adjustable from 400 Hz to 6 kHz
Optional Remote Control: The amplifier has an RJ-25 jack for adding the optional RUX-KNOB.2 wired remote level control for adjusting the channel 3/4 output remotely. The remote has a 20dB adjustment range (-20 dB to 0 dB relative to the gain setting).
Connections
Terminal Layout: For wiring convenience, all of the amplifier’s inputs and outputs are on one side.
Power/Ground: Two set-screw terminals connect the power and ground cables. The terminals accept up to 4-gauge wire (a 4-gauge wiring kit is recommended). The set screws are tightened/loosened with the included Allen wrench.
Remote Turn-on: The remote turn-on set screw terminal will accept up to 8-gauge wire. The set screw is tightened/loosened with the included Allen wrench.
Speaker Outputs: The four pair of speaker outputs’ set-screw terminals will accept up to 10-gauge wire. The set screws are tightened/loosened with the included Allen wrench.
Signal Input: Two pair of RCA jacks, labeled Channel 1/2 and Channel 3/4, connect to line level or speaker level input signals. If connecting the source unit’s speaker wire to the input jacks, use a Speaker-to-RCA adapter or splice speaker wire to an RCA plug. When using a speaker level input signal, it may not be necessary to connect a remote turn-on lead because of the amplifier’s remote sensing function.
Fuses: The two 30-amp ATO fuses protect the amplifier. Another fuse (60-amp minimum) should be placed on the +12V power wire within 18″ of the battery.
