I have the HK695-01 Sub-woofer. I've connected two PC speakers into the left/right connections of the subwoofer. Where do I connect the single cable from the woofer to my desk top? Mike inpt or where. I have a Dell 8200 Demension. I had it connected previously with no problem. Now when I connect it after moving to a new address, I get no sound. I forgot where it was connected previously. Thanks for your help and assistance.
