Passive Subwoofer Question

Hello all..I am new to this forum,
I am currently running an older Paradigm passive sub(with crossover built into it) from my very old receiver. I have the L/R spkr outs going into a power amp, then into the sub inputs with the sub's L/R spkr out going to my main speakers. This actually works well!! I have just been given a working older 5.1 receiver that is far more powerful than my older(Lafayette) receiver. Can I use the same power amp to enhance the output of my passive Paradigm when I connect it to my newer 5.1 receiver through its (I believe an LFE) RCA subwoofer out and then put all of my speakers directly into the receiver. Thanks in advance for all of your advice!

If the power amp has an RCA input, you should be able to continue using it to run your sub.

What are the make & model of the sub, the power amp and the AVR?

You might want a "Y" cable to split the signal to your old receiver if your new receiver only has one RCA output for the sub. If your new receiver has multiple sub outputs, they usually carry the same signal, so then you could use a typical RCA pair cable.

You'll enjoy the feature of "bass management" that the 5.1 receiver brings: now you can block the subwoofer's range of frequencies from your main speakers, freeing them the effort of reproducing them. Or if you prefer them to keep doing so, at least now you can adjust the relative level of the sub far more easily.

Sources/processing: stack of stuff that if it isn't vintage now, it will be soon!
Amps: stacks and stacks of old iron
Main speakers: big DIYSG
Surrounds: Bose graveyard
Subs: a bunch
