Subwoofer connectivity question

I've got a lightspeed attenuator, a prima luna prologue 5 and a Parasound Z Dac.

What is the best way for me to hook up a sub? I was thinking if I could find a sub with RCA inputs and outputs, I could put the sub in line between the lightspeed and my amp. If the sub filters the signal so that its sending a high pass signal via RCA's, if I put in line before the amp, it would only be amplifying 80-100 hz and higher thus relieving some of the load of my amp in the process.

Anyways, what are your ideas on the best way to hook up a sub to this particular set-up (DAC, Lightspeed, Amp...)?

Thanks for your time and input!

Hi
Ok, I am trying to think.I am not familiar with the lightspeed unit but it's probably a passive preamp. What is your source? Your source is connected with RCA so you buy and use a Y RCA connector to split the signal,assuming you buy a powered sub . Signal would be going to the sub AND your setup at the same time.Powered subs have besides other controls also a volume control build in .Another option would be to use the speaker connections of your Primaluna ,some subs come with speaker connections but I prefer the Y RCA splitter myself.
