I'm guessing your sub isn't powered either (as in, it doesn't have a power cord).
You need a new powered sub with a sub out (one RCA cable) or standard L/R RCA out (in which case you'd need the Y adapter).
What you can do in the mean time, and it's SUPER ghetto.....
Is hook up the old receiver, hook the old sub into that.
And then output the old receiver to the new one with a Y adapter into the sub out.
Then crank the volume on the old receiver.
Basically, using the old receiver to power the old sub.[/quote]
I was afraid of that...the ghetto option won't work for me, that receiver took way too much space. Guess this Onkyo wasn't as cheap as I thought, now I need to find a cheap subwoofer...all I see on amazon is $150-300 range...thanks for the info Dallow
