About the Alpine S2-A36F

Buck Pomerantz

High-resolution power

Alpine's Next Generation S-Series S2-A36F 4-channel amplifier delivers 60 watts RMS of pristine high-fidelity signal to each of your car's front and rear speakers, adding sweet, clear sound to your ride. The amp's extended high-frequency response brings your music to life, with its precise details and emotional power clearly revealed. For a 3-channel 2-way system, you could also use the amp to drive a pair of front speakers with 60 watts RMS each, while powering a subwoofer with 180 Watts RMS from the bridged rear channels. A variable mid-bass boost on those rear channels allows you to dial in some extra kick and impact to your system's low-frequency sound. You can even add an optional wired remote to control the level of the rear channels from your front seat.

More convenient features

High- and low-pass filters put you in command of the frequency spectrum that reaches your speakers and subs. The amp includes preamp- and speaker-level inputs, so you can install it in almost any vehicle, even one with a factory radio. When using the speaker-level inputs, the amp can sense the incoming signal and turn itself on, eliminating the need to run a separate turn-on wire to the receiver or fuse box.

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: 60 watts RMS x 4 into 4Ω
  • Signal to Noise Ratio: 83 dBA (measured at 1 watt into 4Ω)

Other Specifications:

  • Power Output:
    • 2Ω: 90 watts RMS x 4 (14.4 volts, =1.0% THD+N)
    • Bridged: 180 watts RMS x 2 (14.4 volts, into 4Ω)
  • Signal to Noise Ratio: 98 dB (at rated power output, into 4Ω)
  • Frequency Response:
    • +0/-3 dB (1W into 4Ω): 10 Hz - 30 kHz
    • +0/-1 dB (1W into 4Ω): 20 Hz - 20 kHz
Controls

Gain Control: There are independent rotary gain controls for Channels 1/2 and Channel 3/4. The amp will accept preamp level signals from 0.2 volts to 4.0 volts or speaker level signals from 0.5 volts to 10 volts.

Turn-On Type/Input Level: A 3-way switch lets you select both the amp activation method and the input signal type. Choices include:

  • DC/HI: Used when running speaker-level inputs and using DC offset to trigger the amp.
  • REM/HI: Used when running speaker-level inputs, but using a +12V trigger wire (REM) to activate the amp.
  • REM/LO: Used when running RCA pre-amp signals into the amp and connecting a +12V trigger wire (REM) to activate the amp.

Crossovers: Channels 1/2 and 3/4 have independent crossovers. Each crossover has a 3-position switch to direct how it operates and both crossovers have a slope of 12 dB/octave.

  • 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

Mid Bass EQ: A rotary dial lets you add 0 to +12dB of boost at 100Hz.

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

Power/Ground: Two set-screw terminals connect the power and ground cables. The terminals accept up to 8-gauge wire (an 8-gauge wiring kit is recommended). The set screws are tightened/loosened with the included 2mm 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 2mm 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 2mm Allen wrench.

Signal Input: Two pair of RCA jacks, labeled Channel 1/2 and Channel 3/4, connect to preamp 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 40-amp ATO fuse protects the amplifier. Another fuse (40-amp minimum) should be placed on the +12V power wire within 18" of the battery.

Q
WHICH SPEASKERS ARE SUITED FOR THIS AMP?

Greetings Shinoj. Thank you for your question. There will be too many to list in this answer. Any speaker you like as long as they can take 60 watts of RMS power. So if the speakers are rated for 60 watts RMS, or more, you can use this amp.
