I have the Powerstage system with 2 amps, one got mounted up front above my brake pedal, it has DSP, crossover, and amp. I'm only looking to replace the sub amp so I can have control of the output. Yes, it makes sense it's speaker level inputs and power, but it appears some of the wires go from one amp back to the other.

Maybe, but is it line level inputs or speaker, and which go back to the head unit, and which to the DSP?

That's a great idea, but you think it's going to be possible to get the wiring diagram of the existing amplifier so I can splice it into the new one? I don't know if Stillwater designs gives out wiring diagrams for their VSS Subs.

Does anyone have pictures of the KICKER PowerStage Subwoofer amplifier (The one mounted on the sub), specifically the wiring harness and model number? I have a 2018 with the VVS Kicker System, and it doesn't have any DIP switches and option for the CXRAC Remote Gain Knob. I called Stillwater Designs and asked how I can add the Gain Control, and they said it wasn't possible. If the Sub amp has the same wiring pinout, maybe I can buy the 2019 sub amp with the gain option and install it on my 2018 Sub. My problem is on certain radio stations at low volume levels, the sub is pounding like crazy, I can turn down the bass, but then I'm in the negative on the scale and I loose all the lows, not just the Sub low frequencies. If only the Sub had the gain control!
