The first thing I did for my home audio was run speaker wire through the attic. Come to find out my receiver does not have a speaker wire out for the sub. Is there a way to connect RCA's to speaker wire. Another possible problem is the receiver only has 1 out for the sub, I'm assuming this must be the left side? But the sub has input's for R and L. Will this be a problem?
Thanks for any help

JH, your sub may accept high(speaker level) input, in which case you are fine.
A 'Y' splitter is usually employed to take your LFE output from a single end at the receiver to the stereo input on the sub.

Hope this helps.

Nuck,
I understand what your saying, and that may be my only choice. What I want to avoid is getting back into my attic (in florida). I already have all the speaker wire run and would like to utilize this if possible.

If your sub has speaker level inputs, then you just connect them to your regular speaker terminals, 2 wires per connection.

Coward, put in a bathroom vent while you are up there.

Haha, the less time I spend in that attic, the better.

So your saying I dont have to use the designated sub output on the receiver. Just the regular speaker outputs will work?

If your sub accepts speaker level inputs, yes.

What is the sub?

Or is this where the details come in?

I am gonna be in FLA week after next, and while that helps neither your sub-connection, nor your present ventilation of the facilities, I can imagine that the attic is not a great space for a campout.

It definitly is not. The sub is a Polk Audio. Model # RM6750. It came in a Polk Audio 5.1 speaker set up. The receiver is a Yamaha RX-V565
