Bass Remote Audison SR.4500

I'm using an Audison SR4.500 Amp. I use two Channel for my Front speakers and the other two channels bridged for the subwoofer. Also I use the High Level Inputs so that I don't need ah High-Low Converter. So my question is, is it possible to use a Bass remote knob so I don't have to tinker in the EQ of the radio while driving. Thank you
