Hi, again!! Come on, I`ve been waiting all day and I`m just off to bed. Not one reply to my question which I posted this morning!! Simply put: is it really simple to connect the B&W AS1 sub to my Denon amp. At the back of the Denon is one RCA phono socket, says subwoofer pre out. I enclose a picture of the AS1. Do I simply connect an RCA Y cable as there are line in and line out connections? That would suit me very well. Or do I have to re-connect my speakers (B&W XT4`s) to the sub?...I need to know quick before the one that`s for sale goes. Please tell me the RCA Y cable alone will do the job. Goodnight. And thank you.
