That's good except the Y connector should have one *female* RCA and two *male* RCA plugs unless you also used a female to female coupler.

He did mention that he had a "cable assembly" with 2 males on one
end and 1 male on the other.

That is what he said and I sort of understand it but I hope he doesn't
mean he fed the combined left and right channel "out" into the sub
woof "in". He has a mono now if he did because they are shorted
together.
I haven't really been following this that closely tho. My eyes glazed
over when they started talking about stereo systems approaching 10
grand. That is a nice outboard, that sounds better than any stereo to
me ;-)



No. Most 5.1 and 7.1 receiver/amps have a single RCA "subwoofer" output
that passes the combined bass from both main channels. Bass isn't
"directional" so there's no need for two subwoofer outputs.

Most powered subwoofers (at least the ones I've had) have *two* line
level inputs. Sometimes one is labeled as "LFE" (low freq effects)
and the other is usually not labeled. For best performance overall,
you put a "Y" connector that feeds the single sub-out on the
receiver/amp to *both* of the line level (female RCA) inputs
on the sub.

OK that makes sense now. My sub woofs only have one "in" but they
don't cost as much as a good used car. ;-)
It does explain the Male to Male/Male tho if the cable is long enough
to connect both components.






Yeah, when I was looking for a picture of a "Y" connector I noticed that
some receiver/amps are now including two sub-woofer outputs instead of
the typical one. The reason is to allow having two subs shaking the
room instead of one. People tend to get carried away with
bass, IMO. Other than rap music or movie special effects the bass
should be more subdued than what most people set it at.
