If I understand you correctly what you're proposing to do is this:
Run a pair of RCA cables from the left and right outputs to a "signal booster"...
Then run the two outputs of the signal booster through a Y-cable to your sub via a single RCA cable.
This could be just fine... or a REALLY bad idea... depending on the circuitry inside that "signal booster".
When you split a single output into two by busing a Y-cable there is no problem - because a single output will have no problem running multiple inputs.
HOWEVER, when you connect two outputs together using a Y-cable, you are SHORTING THOSE TWO OUTPUTS TOGETHER.
Now, depending on the circuitry inside that booster, that may or may not be a problem.
For example, on one of our big processors, it wouldn't damage anything... (although you would be shorting that output to mono)
HOWEVER, depending on the output circuitry in your "signal booster", shorting the outputs together could cause distortion, or could even actually DESTROY the output circuitry.
Therefore you should not short the tow output son your signal booster together unless you're sure it's safe to do so.
The safe alternative would be to use a PAIR of RCA cables between the signal booster and the sub (the two RCA inputs on a sub are NOT shorted together - they are summed through resistors).
Time to revisit this topic as it’s been some time since the question has been posed.
I’m going to run a sub via RCA out. No sub out. I plan on summing the left and right and running them 26’ around the room.
Actually, I’ll run a RCA cable out to a signal booster and then a Y cable out to sum the signal. Then I’ll have a single sub cable run the rest of the distance.
How would you solve my dilemma?
Thank you for whatever advice you share.
