I recently purchased 4 Aura Bass Shakers for my couch and love seat. I have a AudioSource 5.2 amp powering them with a 4ohm load. The signal is coming from a Yamaha RX-V1400. I have not been able to get much movement from these shakers or at least as much as I thought. According to the specs of the amp each shaker should be getting about 37.5 watts which is in the power range. I have the sub-out on my amp is split to go to a power amp for my DIY subwoofers and to my amp for the bass shakers. I originally thought the signal was week because of all the splitting but when I just connected the bass shakers it didn't improve any. The subwoofer level on the receiver is already set to +4 to blend the bass with the other speakers.

Does anybody know if there is some sort of trick to these bass shakers? Is there a possibility that I blew the bass shakers? Can that even happen? I am not sure how similar these are to speakers. Am I expecting too much? I have thought about purchasing a couple of the bass shaker pro's for the main couch but I really don't want to have to spend any more money on this.
