subwoofer advice

I would like to incorporate two or more subwoofers into my stereo setup using one or two powered subs (to be purchased) and a pair of Satterberg passive subwoofers that I already own.  My thought was to use a splitter to connect both my speakers and a powered sub to the speaker out of the amplifier (mc2505). 

Is it then possible to connect the passive subs to the powered subs in such a way that they are being powered by the active sub amplifier, rather than the main stereo amplifier?

If so, is it a good idea, and what features do I need to look for in purchasing the powered sub(s).

Any help/suggestions would be most appreciated.

you need something like this to connect the amp to the sub via the speaker terminals.  Some subs have these build in. some do not.

I don't think you can drive a passive sub through the amp from the active sub but not sure.  I'd just get two SVS or Rythmik sub and be done with it.
Good luck , fun project!

It was the discussion here about the swarm & distributed bass that got me thinking about it.  I already have the two Satterbergs so I'd like to use them if possible along with 2 new subs.

Bjesien - Thanks for the link to the adapter - I anticipate the new subs will have speaker level input capability but if not it could be useful.

Snapsnap, I think you are going about it the wrong way. What you should do is get another pair of passive subs, a subwoofer crossover like the one JL Audio makes and two commercial stereo amps like QSC PLX 3602's. These amps drive subs way better than any plate amp and they are very reasonably priced. 
You could also get a digital preamp that provides subwoofer crossovers like the DEQX Premate. This is better than any analog crossover and it gives you room control.
 Forget trying to match powered subs with passive subs. It will not work well. You either go all passive or all powered. I personally prefer passive. It gives you a lot more flexibility and the opportunity to make your own subs by either Kits or your own design at way lower prices. 
If you have any questions about doing this feel free to message me.
