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.
