I was looking to get some bass shakers from partsexpress.com not the pro models but the less expensive ones. The blurb about them says they do not require much power at all to run them. My question is this: Even though it would not be an ideal hookup, could i run them off of my B speaker output? It would be cheaper than buying an amp, and i could easily turn them on and off when i wanted to use them. They hook up just like regular speakers. Would this work? If not i could use an old sony receiver i have but i am unsure of how that connects. Could anyone explain that to me? Use small words please, i'm just starting in this hobby.
