Quoted from DRDAVE:Are these compatible with the Pinwoofer system?
Hey DRDAVE ! We're only shipping the Knockout Amp ("KO" Amp) for Rush which includes a subwoofer line out. You'll need a 12ft audio cable to route this signal to the external and you won't need anything else. Please put a note in your order and we'll add the cable free of charge (good for all, while supplies last). Thanks for asking!
