a subwoofer dongle anyone tried it ? moderator NOT selling this !

has anyone ever managed to get this dongle to work ? tried to ? thx would like to try it w/ the "new " allison dual sealed push pull subs ! " thinking i will mod the two Klipsch wireless subs I have so i have a switch so I can use their plate amps to power the Allison! or some other external subs have a 1/4 " phono plug or ? so a switch to send the power to the external subs will do some blind A-B ! invite friends over to do the switching !
