I am looking to buy and power 4 Aura Pro Bass Shakers. I know there are threads on powering it, but I am interested in powering it with a Pioneer M-10x Stereo Amplifier
Can I use this if the input is my .1 LFE feed? Or do I need a dedicated Sub Amp with Crossover and gain control?

Your LFE out on your receiver should have a crossover built in. Use that, set it to 80hz (though you can always experiment), and you should be OK using your Pioneer amp, assuming the amp puts out enough power to drive your shakers.

Ok that is what I was thinking... Is there any advantage to using a dedicated Sub amp instead? I haven't bought anything as of yet.. Is this my best option? I'm only looking at the Pioneer to match my Receiver.
