It’s really simple at this point I either run a rca cable from the sub out 1 to the subwoofer itself where it connects to a y splitter that goes to Line In R and L or I can remove the y splitter and plug it straight into the line in port. Which it works buts it’s just not bad ass like it should be so when I go wireless its power is really boosted. When it’s wireless it is going from the sub out 1 to svs triband audio in R LFE. Then the other svs triband connection is coming from the audio out R LFE into the y splitter that goes into the line in R and L in
You don't need a splitter.Have no idea why you are using one.
That's why there is one sub out on AVR's...even if there are multiple sub outs present, they are the same signal.
There is/are no left and right sub outs.
On the RSL the sub in was the left RCA....on the Tonewinner, it's the right.
Edit. Don't know if you have ever posted your AVR settings.
Are you running in Stereo rather than Multichannel ?
In Stereo depending on your settings, many AVR's wont have sub output.
If Multichannel, what are your settings ?
