I would like to hook up two subs to my Yamaha HTR 6080 Receiver. I will be using a JBL L8400P alongside a 12" Audio Profile sub. The second is ported and sounds better with music while the JBL sounds better for HT. I will put them next to both towers to hopefully fill my basement with bass. I've got a Y connector with my shielded cable but don't use both ends since the manual says digital receivers do not require both the R&L connectors. I then went online to find a female to male coax cable to tee off the Y but couldn't find anything. Is there another way of doing this that I don't know of. I imagine some of you run a second amp for this but I'm not ready for this jump yet. Any help would be appreciated.
Thanks
