I needed a y type connector and after getting the wrong one at Wally-Mart (3.5mm audio plug to two RCA male plugs). I returned that and went to the Source. They still had an older one male RCA plug to two male RCA plugs connector cable. Just what the doctor ordered. Base now sounds fine without annoying pops or hum. 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. I think that's what you meant.---This email has been checked for viruses by AVG.https://www.avg.com 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. Looks like in the link below. Doesn't mean *all* setups are likethis but everyone I've ever used is from the Velodynes to a Polkto an inexpensive Sony sub.https://funkyimg.com/i/2T6Kx.jpg---This email has been checked for viruses by AVG.https://www.avg.com


I'll bet that female end connects to another cable, not the reciever?



In the setups I've done, yes. Male to male audio extension cable.
One end goes into the receiver "Sub woofer out". The other male
end to the female on the "Y" connector.
