Can anyone shed some light on hooking up multiple pins to the PSW10? I usually connect two pins to each PSW10 via speaker wire. I have a Stern that has the Pinovators sub kit using the line connection (RCA cables). When I connect the pin, I lose the sound on the speaker wire connections and only have sound on the pin using the RCA jacks. I imagine this is by design however is there a way around it so I don’t have to use a dedicated sub for this machine?
