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.
