Well lads. I am just after getting a new subwoofer today and I am going to connect it up to my Yamaha RX-V363 AV Receiver. I have 2 Tannoy mercury f1 Custom speakers hooked up to it already. Now I wish to connect this active sub to the receiver. I have never done this before so I am unsure what I am meant to do. I got this RCA cable with it.. Do I just plug the white and red parts into the sub and the black part into the receiver? Or do I take the speaker connections out of the receiver and hook it up right into the Sub itself along with the RCA connection?? Help lads!! Cheers!
