Pre amp to sub hookup, or speaker level?

If my pre only has one set of main outputs, how do you recommend hooking up a subwoofer? Is it better to use a Y adapter and split the signal out of the pre, or run a second set of speaker wires from the amp? Is it ok to run a second set of speaker wires off my 2 channel amp, or does that interfere with its main speaker driving duties? Thank you

What kind of inputs and outputs does your sub have? A high level connection uses the speaker wires, a low level connection uses the RCA plugs into your amp. Need some more info for a proper answer.

Is your sub passive or powered? If passive, you MUST provide amplification and run speaker level to it, but don't just bug off the same terminals as your main speakers. You'll need another amp and y-connect the pre to both amps. If powered probably the best way is to run line level to the sub, adjust the crossover/filter appropriately, and return (adjusted) line level to your amp. If this makes no sense, keep posting and we'll get into more detail.

my sub is powered. It has both speaker level and line level. My question remains. Is it ok to run a second set of wires off my main amp, or should I split the signal from the pre?
I thought my question was clear, apologize if it wasn't
