How a passive radiator works ? Answered

Hi,
I already made a topic for a speaker so everything for now is going forward, but now there is a thing that I don't understand.
How a passive radiator works ?
I bought these : http://www.ebay.com/itm/2pcs-40-70mm-Bass-Film-4070-Bass-passive-board-Bass-diaphragm/151785155803?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D37115%26meid%3D601cf622b593403580c218ae762baf34%26pid%3D100005%26rk%3D1%26rkt%3D6%26sd%3D151785222974

But I don't know how I have to power them and connect them to my full range/tweeters speakers with my amplifier.

a passive radiator acts as buffer for large displacements, converting what would otherwise be backpressure on the active speaker into audio.

You don't power a passive radiator. you install it in place of a pressure-relief "sound hole"
