Hey I know this is a bit of a stretch but i was wondering if there was anyone who had any knowledge of converting a passively powered sub woofer (Boston Acoustics model: substat6 series II pv12 power vent module) into an active one. I'm pretty decent with electronics, soldering, general circuitry theory so if it's kind of an advanced level endeavor I'm down for that. Additionally my amplifier is a Yamaha natural receiver AV H.T.R 5540 and it only has what look similar to RCA audio plugs (like the white and red ones that people have for A/V cables for DVD players etc) and the sub only has speaker wire attachments. If anyone even has a good audiophile forum they could direct me too it would be awesome.
Good luck with that. You're going to need to completely redesign the system.
Theoretically, you should just be able to remove the passive's amp and hook the sub's wires into the sub channel on the stand alone amp. I'm not sure why you would want to do this though. If you are trying to pump more power through it, remember, the max volume is usually the max for a reason.

Wait, I think I'm miss-reading the OP. What kind of outputs do the woofer and amp have currently?

Ok, the RCA plugs you are looking at are the inputs, what kind of outputs does the amp have?

Isn't the definition of a passive electronic device not having any amplification?
All the subwoofer needs is an amplifier with enough power.

Yea, I got a tad confused for a minute. I though he had an active that he wanted to turn into a passive.

So, you're wanting to split the input like so?
I can't understand what's the problem, just get a plate styled subwoofer amplifier that has line-level RCA input and screw it into the subwoofer cabinet, solder high-level signal with the subwoofer element, connect line-level RCA input to the amplifier's sub-out/line-out, and put the power cord to the electric socket. That'll provide your subwoofer the correct sort of amplified and filtered signal, so your subwoofer won't sound funky trying to reproduce really high frequencies that are normally delivered with a high level signal (speaker wire)
I mean this sort of a subwoofer amplifier
