These amplifiers offer great value with over 20% more power through increased watt handling. The exceptional strength and resistance is supported by optimising a heat thermal management processor to ensure exceptional reliability so you can enjoy your music with the bass cranked up for hours on end without any power shutdown.

Key Features:

All Digital Design

• The all-new S-Series utilise Alpine’s advanced digital design which unlike a typical Class-D amplifier circuit adds all-digital dual post-filter feedback loop for unmatched accuracy and control, while minimising internal noise.

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 hand side of the amplifier providing an easy and clean installation. The power cable terminals accept heavy gauge cables.

Low/High-Power Speaker Signal Inputs

• The S-Series amplifiers are equipped with low-level RCA inputs, which can also accept high-level speaker signal inputs. This allows for installation of the R-Series amplifiers into virtually any aftermarket or OEM factory audio system.

Control Your Subwoofer

• Conveniently control your subwoofer directly from the dash with the optional RUX-KNOB.2 remote bass knob controller. This accessory is also applicable for the S-A32F for when channels 3 and 4 are bridged.

High-Pass / Low-Pass Filter

• With the High-Pass and Low-Pass filter you can assign the amplification channel to be used for door speakers or a subwoofer. You can then adjust the cut-off frequency for more precise tuning.
