Hi I need some help... I'm very much an amateur in electronics and I'm trying to hook up a set of surround sound speakers from an old KLH Audio system to my Insignia IS-HC040917 receiver. The speakers are fine but I'm having an issue with the subwoofer. The subwoofer I have has jacks on the back to accept bare speaker wire but the "SW Output" on my receiver is like an RCA jack. I saw an earlier post on here where one of the recommendations was to cut off one end of an RCA connector and strip back the insulation to get the bare wire. I did that and hooked everything up but I still get no sound from the sub. Can anyone help me?
