Key Features

Alpine SSeries 1100W 5 Channel Class D Car Amplifier - Alpine Car Audio Systems S-A55V

Alpine introduces the all-new S-Series amplifiers - a perfect match to the S-Series speakers. These amps have an excellent Watts-per-Euro ratio in the Class-D category, feature a very high heat resistance and won’t shut down due to overheating. They also feature excellent sound quality in their price range.

The S-Series amplifiers are available in mono, 4-channel and 5-channel configuration.
The Alpine S-Series Sound Components
Three new S-Series amplifiers join the S-Series family, known for reliable performance and value-oriented products. All three S-Series amps (mono, 4-channel and 5-channel) contain technology currently implemented in R and X-Series models. The S-Series amps feature attractive prices and are designed to perform perfectly with the existing S-Series speakers. 
All Digital Design
Compact and Powerful: the new digital amplification circuit allows high power output while keeping a small footprint. The S-A55V measures just 286mm in width x 204mm in length for easy installation in virtually any vehicle. 
Thermal Protection
Along with Alpine’s new intelligent amplifier platform, the new S-Series amplifiers feature an improved heat sink and protection circuit design that eliminates thermal shut-down, for dependable music playback. 
One-sided Cable Terminals
The speaker and power cable terminals are conveniently located on the left side of the amplifier to allow a clean installation. The power cable terminals accept heavy gauge cables 
Control Your Subwoofer
You can connect the RUX-KNOB2 remote bass knod (optional available) to the S-A55V to controll the subwoofer level straight from your dash (applicable only for channel 5 for subwoofer usage). 
High-Pass / Low-Pass Filter
With this filter switch you can assign the amplification channel (pair) to be used for door speakers or a subwoofer. You can then adjust the cut-off frequency for more precise tuning. 
Low/High-Power Speaker Signal Inputs
The 5-Channel RCA speaker signal inputs accept low and high-power signals. This makes it easy to connect the S-A55V directly to your original car stereo, regardless of your head unit’s power output (RCA connectors with open cable leads are available separatly).

Nicolae on 10/12/2020 5 star rating

Had fitted this amplifier into my car, an Alfa Romeo Giulietta at Nottingham Store. The work was great! Thank you, guys. Clear sound, crystalize. Was what I was looking for. Highly recommend with Alpine Car Audio Systems Alpine RS-65C.2 - 300W 17cm 2-way component speaker system.

  • Question: 26 September 2021
    Car: BMW 5 Series (E39) - 2004> (E60)

    can i bridge the 4 the channels into two to run at 120 watts RMS * 2 but use the mono channel in 2 ohm at 300 watts RMS.


    That's not possible. You wont be able to use the mono if you decide to bridge.

  • Question: 24 May 2021
    Car: BMW 1 Series (E81) - 2004> (E81)

    With two 2Ω 200W DVC subwoofers in Parallel/Series, the combined impedance would be 2Ω. Would the 5th channel's 300w be sufficient to run two 200w subs?


    No, you would be underpowering the subs which could damage them/cause the amp to overheat.
